Description

LEPIDOPTERICIDAL ISOTHIOUREA COMPOUNDS

Background of the Invention

Lepidoptericidal isothiuronium compounds have been disclosed in the prior art particularly those described in U.S. Patents 3,969,511 and 4,062,892 and have the formula

These compounds have a major disadvantage in that they show high levels of phytotoxic activity and thus, although controlling lepidoptera in the crop to be protected, are detrimental to the crop itself. To overcome this problem, applicants have discovered that substitution of the active hydrogen on the above type of isothiuronium and urea compounds with certain specific, relatively easily cleaved groups can lessen or eliminate phytotoxic effects of the parent compound while maintaining, and in some cases enhancing, the lepidoptericidal activity of the compound.

No prior art has been discovered which teaches or suggests the result that applicants have achieved. Description of the Invention

The compounds of the present invention are derivatives of isothioureas containing one free hydrogen atom attached to nitrogen, that is, as shoxra by the following formula:

The formation of the prior art isothioureas is well knoxm in the art. They are derived by the reaction of an isothiocyanate xtfith a primary amine to form a thiourea followed by the reaction with an alkyl halide to produce an isothiourea salt. An unreactive solvent such as ethanol can be used for both the formation of the thiourea and the alkylation step to form the isothiourea salt. Heat is usually used to speed both reactions. The preparation of the isothiourea salt is shown below:

The compounds of this invention are prepared by reacting the base of an isothiourea with an isocyanate or acid chloride. The free base can either be prepared by neutralization of an isothiourea salt with a cold aqueous solution of atase such as dilute sodium hydroxide, extracting the free isothiourea with a water insoluble solvent such as hexane, benzene, toluene, etc., drying over a dehydrating agent such as magnesium sulfate, filtering and evaporation under vacuum. An alternative procedure is to dissolve the isothiourea salt in a non-reactive solvent such as benzene or toluene then add ing an equal molar amount of an isocyanate and the equivalent amount of a soluble tertiary base or an acid chloride and two equivalent amounts of a soluble tertiary base such as triethylamine, completing the reaction by stirring at ambient temperature for several hours or refluxing for a shorter period of time. An alternative method when using a base such as triethylamine is to treat the isothiourea salt in a solvent such as benzene in which triethylamine hydrohalide is almost totally insoluble, filtering off the triethylamine hydrohalid and treating the filtrate with the isocyanate or acid chloride, completing the reaction as discussed previously. Solvents suitable for the condensation of the isothiourea with an isocyanate or acid chloride are those which are unreactive to any of the reactants. These include hexane, benzene, toluene, tetrahydrofuran, dioxane, methylenechloride, diethylether, and the like. Depending on the reactants, reaction temperatures are generally within the range of -20°C to 80°C and reaction times vary from 0.5 hours to 24 hours.

In some instances, it has been found that the condensation of an isothiourea with an isocyanate or acid chloride can be hastened by the addition of such catalysts as triethylamine and dibutyltindilaurate. Equations showing the reactions just discussed are as follows:

A) Using isothiourea base with an isocyanate

B) Using isothiourea salt + a base

C) Using isothiourea base with an acid chloride

The isothiourea precursors of the prior art discussed above can in general be prepared by the methods disclosed in U.S. Patents 3,969,511 and 4,062,892.

These compounds are useful as lepidoptericides when used in a lepidoptericidally effective amount on insects of the order lepidoptera or their habitat or feedstuffs. Some of the compounds also show phytotoxic effects which could render them useful as herbicides as well as lepidoptericides if such efficacy was desired. In addition, some of these compounds show biocidal and/or fungicidal effects.

By "lepidoptericidally effective amount" is meant the amount of the herein disclosed lepidoptericidal compounds which when applied in any conventional manner to the habitat of the lepidoptera, the feedstuffs of lepidoptera, or the insects themselves, will "control" by killing or substantially injuring a significant portion of the lepidoptera.

These compounds are useful in protecting food, fiber forage crops and ornamental crops from damage by insects and larva of other order lepidoptera. Examples of crops to be protected include forest trees such as oak and pine, fruit trees such as peach, apple and walnut, vegetables such as tomatoes, other crops such as tobacco, cotton, lettuce, corn and rice and any crop which lepidoptera feed upon.

The novel compounds of this present invention can be prepared from the above precursors by methods shown in the following examples. 1,3-Diheptyl-2-ethyl-3-(0,0-dimethyl phosphoro) isothiourea

LEPIDOPTERICIDAL EVALUATION

Lepidoptericidal activity of the above compounds were evaluated for efficacy on various lepidopterous species as follows:

I. Salt-Marsh Caterpillar [Estigmene acrea (Drury)]

A test solution is prepared by dissolving the test compound in a 50-50 acetone-water solution. A section of a curly dock (Rumex crispus) leaf, approximately 2.5 cm wide and 4 cm long, is immersed in the test solution for 2-3 seconds, then placed on a wire screen to dry. The dried leaf is placed in a petri dish containing a moistened piece of filter paper, and infested with 5 second-instar salt-marsh caterpillar larvae. Mortality of the larvae is recorded 48 hours later. If surviving larvae are still present, a piece of synthetic media is added to the dish and the larvae are observed for an additional 5 days in order to detect delayed effects of the test compound. The primary screening level for this test is 0.05 percent by weight of the test compound in the solution.

II. Cabbage Looper [Trichoplusia ni (Hübner)]

The procedure for cabbage looper larvae is the same as that used for salt-marsh caterpillar larvae, except that a cotyledon of hyzini squash (Calabacita abobrinha) of approximately the same size as the curly dock leaf section is used in place of the latter. The primary screening level for this test is 0.05 percent by weight of the test compound in the solution. III. Tobacco Budworm [Heliothis virescens (F.)]

Larvae of the tobacco budworm are used in this test in a procedure identical to that used for saltmarsh caterpillar larvae, except that a Romaine lettuce (Latuca sativa) leaf section of approximately the same size as the curly dock leaf section is used in place of the latter. The primary screening level for this test is 0.1 percent by weight of the test compound in the solution.

Table II summarizes the results of the lepidoptericidai tests performed on the compounds of Table I. These test results are expressed as LD₅₀ values, which represent the dose of test compound which was lethal to 50 percent of the insect population in the test. The entries in Table II were obtained as follows:

For a particular lepidoptera, each compound was initially tested at the primary screening level. Those compounds showing less than 50 percent kill at this level are represented in the table by the primary screening level preceded by a "greater than" sign ( > ). Those compounds showing approximately 50 percent kill are represented by the primary screening level alone. Those compounds showing greater than 50 percent kill were subjected to further testing at successively lower levels, until the level was found at which approximately 50 percent kill was achieved. The latter level is listed as the LD₅₀ for this group. Phytotoxicity Tests

Phytotoxicity tests are conducted on cotton (Gossaypium hirsutum) and hyzini squash (Calabacita abobrinha) seedlings. Plants are grown and treated in Kaiser No. 1059 6" × 9" × 3" aluminum flats. Each flat contains one row of cotton and one row of squash, with 6-8 plants per row. The plants are grown in the greenhouse and are treated when they are approximately 8 days old and 2" tall.

Technical test compounds are diluted in a 50-50 acetone-water solution and formulated compounds are diluted in water. These test solutions are then sprayed on the flats in a Ducon-Savko Model 3400 linear spray table atrates of 1/2, 1, 2, and 4 lbs a.i./80 gallons/acre. The treated plants are then placed in the greenhouse and watered in such a way that the foliage is not wet.

One week later, the treated plants are inspected and the degree of phytotoxicity is subjectively rated from 0 to 5 as follows:

0 = no injury

1 = slight injury

2 = slight to moderate injury

3 = moderate injury

4 = moderate to severe injury

5 = severe injury or dead

Table II also summarizes the results of the phytotoxicity tests performed on the compounds of Table I. The primary screening level in each of the above tests was selected for purposes of convenience only, and none of the figures in the table are to be understood as representing the highest level at which a viable test for lepidoptericidal activity can be conducted.

Biocidal Tests

In Vitro Vial Tests

Tubes of sterilized nutrient and malt extract broth were prepared. Aliquots of the toxicant, dissolved in an appropriate solvent, were injected through the stopper, into the broth, to provide concentrations ranging from 50 ppm downward. The test organisms consisted of one fungi, Botrytus cinerea, and one bacteria, Staphylococcus aureus (S.a.) Roseenbach.

Three drops of a spore suspension of each of the fungi were injected into the tubes of malt broth and three drops of the bacteria were injected into the nutrient broth. One week later the growth of each organism was observed and effectiveness of the chemical was recorded as the lowest concentration in ppm which provided 100 percent inhibition of growth as compared to untreated inoculated tubes. The results are shown in Table III.

Fungicidal Tests

Foliar Preventive Sprays

Bean Powdery Mildew - - The chemicals were dissolved in an appropriate solvent and diluted with water containing several drops of a wetting agent. Test concentrations, ranging from 1000 ppm downward, were sprayed to runoff on the primary leaves of pinto beans (Phaseolus vulgaris L.). After the plants were dry, the leaves were dusted with spores of the powdery mildew fungus (Erysiphe polygoni de Candolle) and the plants were retained in the greenhouse until the fungal growth appeared on the leaf surface. Effectiveness was recorded as the lowest concentration, in ppm, which will provide 75 percent or greater reduction in mycelial growth on the leaf surface as compared to untreated, inoculated plants. The results are shown in Table III.

The primary screening level in each of the above tests was selected for purposes of convenience only, and none of the figures in the table are to be understood as representing the highest level at which a viable test for lepidoptericidai activity can be conducted. The compounds of this invention are generally used in formulations suitable for convenient application. In general, such formulations will contain inert or other active ingredients or diluent carriers in addition to the active compound. Examples of such ingredients or carriers are organic solvents, such as sesame oil, xylene range solvents, and heavy petroleum; water; emulsifying agents; surface active agents; talc; pyrophyllite; diatomite; gypsum; clays; and propellants, such as dichlorodifluoromethane.

The active compounds can further be combined with dust carriers for application as dusts, with granular carriers for application by fertilizer spreaders or ground or airplane seeders. It also can be formulated as a wettable powder or a flowable for application as a water suspension, or with solvents and surface active materials for application as sprays, aerosols, or emulsions. The compounds or their formulated mixtures can be applied to any habitat of the pests. Examples of such habitats are insect dwellings, clothing, plant surfaces, and soil. If desired, however, the active compositions can be applied directly to organic matter, seeds or feedstuffs in general, upon which the pests feed, or directly to the pests themselves. When applied in such a manner, it will be advantageous to use a formulation which is not volatile.

Particularly preferred compositions are those comprising an insecticidally effective amount of the active compound in combination with an inert insoluble solid carrier vehicle. Examples of such compositions are wettable powders, dusts, and flowable formulations, in which the solid carrier is in finely divided form; and granular formulations, in which the solid carrier is a pre-formed granule. These isothiourea compounds can also be formulated to include baits that induce feeding responses in the lepidoptera larva resulting in earlier ingestion of the lepidoptericidai isothioureas. Effective baits include cottonseed flour, cottonseed oil, extract of mature cottonseed, sucrose, invert sugar, citrus molasses, soybean oil, soy flour, corn oil, extract of corn kernels, extract of corn silks, extract of corn seed and mixtures thereof together with suitable emulsifiers and wetting agents.

The amount of active compound or formulation which is considered to be insecticidally effective is that amount which, when applied to the pest habitat or feedstuff, will kill or substantially injure a significant portion residing or feeding thereon. The active compounds of this invention can be employed either as the sole pesticide component of the formulations or as one of a mixture of compounds in the formulation having similar utility. Furthermore, the presentl disclosed pesticide compositions need not be active as such. The purposes of this invention will be fully served by a composition which is rendered active by external influences, such as light, or by physiological action occurring when the preparation is ingested or penetrates into the body of the pest.

The precise manner in which the pesticide compounds of this invention are used in any particular instance will be readily apparent to a person skilled in the art. Generally the active pesticidal compound will be used as a component of a liquid composition; for example, an emulsion, suspension, or aerosol spray. While the concentration of the active pesticide compound in the present formulation can vary within rather wide limits, ordinarily, the pesticide composition will comprise not more than about 50.0 percent by weight of the formulation.
