Description
Liquid pesticide concentrate formulation comprising phenylsemicarbazone compounds
The present invention relates to a liquid pesticide concentrate formulation which comprises at least one phenylsemicarbazone of the formula A as defined hereinafter and to its use for controlling organisms that are harmful to crops.
Agriculturally active compounds can be applied in the form of aqueous emulsions, solutions, or suspensions. Usually, the active ingredients are transported in the form of liquid concentrate formulations for later dilution.
For example, emulsifiable concentrates (ECs) are normally composed of an active ingredient, a surfactant and an organic solvent, and are used after diluting with water to form a milky oil-in-water emulsion, containing the active ingredient dissolved in the solvent droplets.
Microemulsion concentrates (MCs or MECs) have also been described and are understood as meaning a composition which forms microemulsions upon dilution with water. A microemulsion is understood as being an emulsion which is thermodynamically stable and has a droplet size of the emulsified phase which is generally in the submicron scale (frequently 200 nm or below).
One of the problems with such liquid concentrates is the fact that agriculturally active ingredients often exhibit extreme insolubility in water. When attempts are made to provide liquid concentrates, difficulties are encountered with respect to providing a high concentration of the active ingredient. However, it is most desirable to be able to transport the active ingredient at the highest concentration possible so as to minimize transportation costs.
For field applications of pesticides to crops, it is also important that a stable emulsion is formed upon dilution with water, which emulsion does not separate upon standing. Furthermore, there should not be any crystallization of the active from the emulsion after water dilution. In addition, the concentrate itself has to be physicochemically stable during extended storage periods and under widely varying storage temperatures.
Phenylsemicarbazone compounds of the formula A
wherein R1 and R2 are each independently hydrogen, halogen, cyano, Ci-C4 alkyl, C1-C4 alkoxy, C1-C4 haloalkyl or C1-C4 haloalkoxy and R3 is C1-C4 alkoxy, C1-C4 haloalkyl or C1-C4 haloalkoxy, and their agriculturally acceptable salts are known from EP 0 462 456 A1. The compounds of the formula A have a wide pesticidal spectrum against arthropod pests and nematodes, in particular against insect pests.
Like most active ingredients that are used as pesticides, phenylsemicarbazones of the formula A are only sparingly or even insoluble in hydrophilic media such as water. For example, they usually have a water-solubility of not more than 2 g/l, and often much less, at 25°C/1013 mbar.
Several attempts have been made to provide pesticidal formulations of the phenylsemicarbazones of the formula A.
WO 2006/002984 A1 discloses liquid pesticide formulations, wherein at least one organic pesticide compound is dissolved in a mixture of a water-miscible solvent and at least one non-ionic block-copolymer. The pesticide compound may be a phenylsemicarbazone compound of the formula A, among many others. The solvent used is capable of dissolving the active ingredient and may contain water, provided that the weight ratio of water to solvent does not exceed 1 :2.
WO 2006/133928 A2 discloses the use of the phenylsemicarbazones of formula A, or agriculturally acceptable salts thereof for seed treatment and corresponding methods of seed treatment for controlling arthropod pests. Also disclosed are seed treatment formulations comprising the phenylsemicarbazones.
WO 2006/127399 A2 discloses high load concentrate compositions comprising metaflumizone, an optional bridging agent, a surfactant, and a suitable carrier solvent. These compositions may be topically administered to animals, and are useful for preventing or treating ectoparasitic infestations in warm-blooded animals for prolonged periods of time.
WO 2007/017501 A2 discloses an emulsifiable concentrate formulation comprising (a) a phenylsemicarbazone compound of the formula A, (b) a solvent system, comprising γ-butyrolactone, one or more aliphatic and/or aromatic ketones, and optionally one or more aromatic hydrocarbons, (c) one or more emulsifiers, and (d) optionally further formulation additives.
JP 2006131515 A discloses a pest control agent composition containing a hydrazinecarboxamide compound, and at least one compound selected from insecticidal, acaricidal and nematocidal compounds as effective components.
WO 2007/077246 A2 discloses a water-dilutable liquid concentrate formulation, comprising (a) at least one organic pesticide compound having a water solubility of not more than 5 g/l at 25°C/1013 mbar, (b) a solvent mixture comprising i) at least one C2-C4-alkylene glycole and ii) at least one C2-C4-alkylene carbonate and (c) at least one surfactant. The pesticide compound may be a phenylsemicarbazone compound of the formula A, among many others.
WO 2007/1 10355 A discloses agrochemical formulations comprising a) 0.1-50 wt% of at least two pesticides comprising, inter alia, metaflumizone and acetamiprid; or metaflumizone and teflubenzuron; or metaflumizone and flufenoxuron, b) 30-99.8 wt% of at least two polar organic solvents, c) 0.1-50 wt% of a mixture comprising a non-ionic distyrylphenol alkoxylate and a ionic distyrylphenol alkoxylate, d) 0-50 wt% non-ionic surfactant, and e) 0-20 wt% further formulation auxiliaries.
PCT/EP2007/060449 discloses a liquid pesticide composition, which comprises (a) a phenylsemicarbazone compound of the formula A, (b) a solvent selected from water and polyhydric C2-C4 alcohols and mixtures thereof, the pesticide compound of the formula A being soluble in the solvent in an amount of not more than 2 g/l at 25°C/1013 mbar; and (c) one or more surfactants, wherein the compound of formula A is present in the form of particles having a volume median diameter, as determined by dynamic light scattering, of not more than 1.5 μm.
There is still the need to provide liquid concentrate formulations of the phenylsemicarbazone compound of the formula A containing relatively high concentrations of this pesticide, which is particularly attractive from an economic viewpoint. Despite the high pesticide loading, it is further desirable to a have a liquid concentrate exhibiting good stability properties. Upon dilution with water, the formulation should form a stable aqueous composition of the active ingredient, and the formation of coarse constituents should be avoided. In addition, the precipitation of the active ingredient should be prevented upon prolonged storage or storage at elevated
temperatures. It is also an object of the present invention that the liquid pesticide formulations provide good to excellent control against a broad spectrum of insect pests.
Surprisingly, it has now been found that these and further objects can be achieved by a liquid pesticide concentrate formulation in the form of an emulsifiable concentrate or a microemulsion concentrate, comprising
a) a phenylsemicarbazone compound of the formula A
wherein R1 and R2 are each independently hydrogen, halogen, cyano, Ci-C4 alkyl, C1-C4 alkoxy, C1-C4 haloalkyl or C1-C4 haloalkoxy and R3 is C1-C4 alkoxy, C1-C4 haloalkyl or C1-C4 haloalkoxy, or an agriculturally acceptable salt thereof;
b) one or more amides of the formula b1
R°
R-CO-N (b1 )
RD wherein
R4 is C6-C20 alkyl, C6-C20 alkenyl or C6-C20 alkynyl, and
R5 and R6 are each independently hydrogen or C1-C4 alkyl as organic solvent, and
c) one or more surfactants.
The liquid pesticide concentrate formulations of the present invention are effective against a broad spectrum of insect pests. Although the inventive formulations contain relatively high concentrations of the pesticidal compound A, they exhibit good stability over prolonged storage times, also at elevated temperatures, without significant occurrence of phase separation phenomena or noticeable agglomeration of the active ingredients. The high loading of the active ingredient together with the enhanced biology provides excellent value for the end user with several advantages such as a better handling, lower costs and environmental friendliness through low application
rates, as well as low exposure to workers with better safety. The inventive formulations show good to excellent dilution and emulsion characteristics in standard water and also in hard waters. The formulations of the invention also have excellent wetting and leaf absorption properties.

In another embodiment of this invention, the substituents R1, R2 and R3 in the formula A independently of one another, but in particular in combination, have the meanings given below:
R1 is C1-C4 haloalkyl, in particular trifluoromethyl;

1. Preparation Examples
The registered trademarks and other designations utilized herein denote the following ingredients:
Table 1
A series of liquid concentrate formulations (see preparation examples 1 to 6, Table 2) were prepared by weighing the exact proportion of ingredients and mixing them together in a bottle until complete dissolution occurred (if needed with gentle heating). The solvents were weighed first. Compound A1 , i.e. (EZ)-2'-[2-(4-cyanophenyl)-1-(α, α, α-trifluoro-m-tolyl)ethylidene]-4-(trifluoromethoxy) carbanilohydrazide), was dissolved
completely in the solvent system followed by addition of the surfactant and further additives. All preparation examples 1 to 6 gave a clear, homogenous liquid.
In the examples below, all amounts are in weight parts or weight percentages based on the total formulation, unless specified otherwise.

2. Stability properties
2.1 Emulsion stability
The liquid concentrate formulations of preparation examples 1 to 6 were diluted with water at formulation/water weight ratios of 1 :100 and 2:100. Different water hardness conditions were employed (342 ppm, 500 ppm and 1000 ppm WHO hard water). All formulations according to the invention showed good water dilution and emulsion characteristics across the different hardnesses of water. No crystals were observed upon dilution with water.
2.2 Freeze-thaw stability and chemical stability
The preparation examples 1 to 5 were tested for freeze-thaw stability between temperatures of -15°C to 400C. One cycle constituted a total of 24 hours, wherein the samples were exposed to 10 hours at -15 0C and 10 hours at 40 0C with 2 hours of transition from one temperature to the other.
All the samples showed excellent stability after 5 cycles, showing no crystal formation or change in emulsion properties of the concentrate on dilution or in the physical appearance. They were also found to be chemically stable after the freeze-thaw cycles.
Results obtained from the freeze-thaw stability (5 cycles, see above) and chemical stability testing (at different storage times and temperatures) with preparation example 5 are set forth in Table 3 below.
Table 3
*Recovery of 95% or higher at 540C after two weeks indicates good chemical stability.
3. Biological activity
3.1 Activity against imported cabbage worm (Pieris rapae), 3rd instar on cabbage
A stock composition of the formulation of preparation example 4 was diluted into a container of water. Preparation example 4 was tested at 0.3, 1 , 3, 5, 10 and 30 and 100 ppm. Cabbage leaves were dipped into the thus prepared dilution and allowed to air-dry. A single treated leaf disc was each placed topside-up onto water-moistened filter paper in multiple plastic petri dishes. Ten larvae (3rd instar) were placed onto each leaf, and then each arena was sealed with petri dish covers. Each treatment was replicated 4-fold (1 replicate = 1 petri dish arena) with 10 insects. Larval complete
mortality was assessed at 72 hours after infestation. Table 4 lists the LC50 and LC90 data which have been obtained for various concentrations of a.i. (active ingredient) applied after 72 hours of exposure. The LC50 and LC90 was calculated using probit analyses of the mortality observed for the different concentrations of preparation example 4.
Preparation example 4 provided excellent potency against larvae of imported cabbage worm based on LC50/LC90 values (2.413 and 4.7 ppm).
Preparation example 4 also provided good leaf protection based on feeding damage at
1 ppm (31.3 %).

A stock composition of each of the formulations of preparation examples 1 to 5 was diluted into water (100 ml). Lima bean leaves were sprayed with the thus prepared dilution in a sprayer chamber and allowed to air-dry. The sprayer was calibrated to apply 200 I/ha and all the dilutions were based on g a.i./ha. A single treated leaf disc was placed topside-up onto water-moistened filter paper in multiple plastic petri dishes. Seven larvae were placed onto each leaf, and then each arena was sealed with petri dish covers. Each treatment was replicated 4-fold (1 replicate = 1 petri dish arena) with 7 insects. Following treatment application, infested plants were held in the laboratory under fluorescent lighting and at a constant temperature of 26°C. Feeding damage (0- 100%, visual evaluation) was recorded 4, 7 and 1 1 days after application (DAT). The results are summarized in Table 5 below. It can be seen that all the preparation examples 1 to 5 provided not only a good initial activity against Southern armyworm larvae, but also an excellent outstanding performance.

3.3 Activity against Colorado potato beetle (Leptinotarsa decemlineata) in potatoes
Trials were arranged in randomized complete blocks with three replications. Plots were 10m long and one row wide. Applications were conducted with a tractor-mounted sprayer with a three-nozzle row crop boom delivering side and overhead coverage, at 3-bar pressure and 300 I/ha. Numbers of larvae (L1/2) (L3/4) were recorded per plot at 3, 7, 14 and 21 days after application (DAT) and feeding damage was assessed at 21 days after application (see Tables 6, 7 and 8). No crop injury was observed 3-14 days after the application with any of the formulations tested.
It can be seen that all the preparation examples 1 to 5 provided excellent control of Colorado potato beetle larvae.

3.4 Activity against the Diamond backmoth (Plutella maculipennis) and Common cutworm (Spodoptera litura) on cabbage.
Preparation example 4 was tested at the rates of 160, 200 and 250 ppm on cabbage against 2 species being Diamond backmoth and Common cutworm. The product at different rates was diluted in water and sprayed in the field at a spray volume of 2000 I/ha. The youngest unfolded leaves of field planted cabbage plants were marked just before spray application. Older leaves than the marked leaves or the marked leaves were collected at 1 , 3, 7, 14 days after application (DAT) respectively for laboratory bio- assay. Five leaf discs (diameter 2.5cm) were punched out from the collected eaves and put into a petri dish. About 10 3rd instar larvae/petri dish were released onto them and were kept in an insectary under 24°C, 16 hours light / 8 hours dark conditions. Evaluations were done according to SCHNEIDER-ORELLI at 2 and 3 days after insect release. Preparation example 4 provided excellent residual control of both species (see Tables 9 and 10).

4. Penetration into cotton leafs
The penetration into cotton leaves of preparation example 6 was evaluated according to the following procedure:
The formulation of preparation example 6 was spiked with C-14 labeled Compound A-1. The treatment solution was prepared at a concentration of 240 g/ha and diluted with water to 200 I/ha. The treatment solution was applied on the surface of cotton leaves using a microliter syringe in microliter droplets. The treated leaves were allowed to dry in the hood and plants were then placed in the greenhouse. After pre-determined periods of time, the treated leaves were washed in sequence with water, methanol, and dichloromethane. At the end leaf was combusted. The amount of carbon-14 in washes and combustions was determined by LSC (liquid scintillation counter). The percent distributions of residues derived from C-14 Compound A-1 of the applied dose in cotton leaves were then determined.
The results of leaf absorption tests with preparation example 6 indicate that approximately 27% of the applied dose of C-14 labeled Compound A-1 were absorbed into the cotton leaves after 14 days. Thus, upon applying aqueous emulsions of this concentrate on the surface of cotton leaves, excellent penetration through the wax layer of the leaves could be observed.
