Abstract
The invention discloses a thiamethoxam and imidaclothiz complex insecticide which is characterized in that the active ingredients comprise thiamethoxam and imidaclothiz, wherein the residual aid or excipient is supplemented to the 100 percent of insecticide; and the weight ratio of thiamethoxam to imidaclothiz is (1-85):(1-85). The insecticide has a good effect of removing rice planthopper, aphid, leafhopper, thrips and other homoptera insects with easy resistance and can inhibit the insects to generate medicine resistance on a single thiamethoxam and imidaclothiz preparation, and the actual using effect is obvious. The thiamethoxam and imidaclothiz are complexed, so that the effects of effectively controlling most of sucking pests and reducing the environmental pollution are achieved, the pesticide effect and lasting period are improved, the labor cost of farmers is reduced, and the insecticide has good economic benefits.
Description
Technical field
The present invention relates to a kind of thiophene worm piperazine and imidaclothiz compounded pesticides, belong to the agricultural insecticide technical field.
Background technology
Thiophene worm piperazine, English common name (Thiamethoxam), chemical name 3-(2-chloro-1,3-thiazoles-5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine.Thiophene worm piperazine is a kind of second generation nicotinoids high-efficient low toxicity insecticide of brand new, insect is had stomach toxicity, tags and systemic activity, the alternative insect central nervous system nicotinic acid acetylcholinesterase acceptor that suppresses, and then the normal conduction of blocking-up insect central nervous system, death when causing insect the paralysis machine to occur.Be used for foliar spray and soil root irrigation.Rapidly by interior suction, and be transmitted to each position of plant after its dispenser, sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc. are had good preventive effect.Characteristics such as have higher activity, better safety, wider insecticidal spectrum and speed of action is fast, the lasting period is long are to replace those better kinds to mammalian toxicity height, the organic phosphor that residual and environmental problem are arranged, carbamate, organochlorine insecticides.
Imidaclothiz, English common name (imidaclothiz), the inferior imidazoles of chemical name 1-(5-chloro-thiazolyl methyl)-N-nitro-2-base amine.Imidaclothiz is a kind of anabasine insecticide, its mechanism of action is that the cynapse acceptor to insect has the nerve conduction blocking effect, has stronger interior absorption, be 20 times of general anabasine insecticide activity such as pyridine worm miaow, Imidacloprid, imidaclothiz is not limited by or not the temperature highland, has overcome the shortcoming of products such as pyridine worm miaow, Imidacloprid anti-heterodyne when temperature is low.Imidaclothiz toxicity is low, meets the pollution-less agriculture production requirement, and insecticidal spectrum is wide, can be used on the various crop except insects such as control water rice hopper, leafhopper, thrips.
At present, the agricultural chemicals main means of making agricultural pests as chemical control are used very extensive.Yet, use the agricultural chemicals of single variety for a long time, impel insect to produce certain resistance easily, peasant household often increases the weight of the consumption mode of agricultural chemicals by employing for this reason, to reach the purpose that eliminates destructive insects.But adopt this mode just to exist, environment is caused bigger pollution and the problem of residue of pesticide, also improved the drug cost of peasant household simultaneously indirectly.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of consumption is relatively low, drug effect is obvious, drug cost is low, have quick-acting and long-acting characteristics.
For solving the problems of the technologies described above, technical scheme of the present invention is: 1. a thiophene worm piperazine and imidaclothiz compounded pesticides, its innovative point is: active ingredient comprises thiophene worm piperazine and imidaclothiz, all the other used additives or excipient complement to 100% insecticide, and wherein the part by weight of thiophene worm piperazine and imidaclothiz is 1～85: 1～85;
Further, the preferred part by weight of described thiophene worm piperazine and imidaclothiz is 5～80: 5～80;
Further, the part by weight of the best of described thiophene worm piperazine and imidaclothiz is 10～70: 10～70;
Further, described auxiliary agent be in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether phosphate, alkylaryl polyoxyethylene polyoxypropylene ether, sodium lignin sulfonate, polyoxyethylene poly-oxygen propylene aether and sulphate thereof, xanthans, ethylene glycol, silica ethane, aluminium-magnesium silicate, ammonium sulfate, polyvinyl alcohol, Negel, the polyoxyethylene nonylphenol ether wherein one or more;
Further, described excipient be in isopropyl alcohol, vegetable oil, solvent naphtha, water, antifreezing agent, deionized water, borax, diatomite, the kaolin wherein one or more;
Further, be added with wherein a kind of in auxiliary agent and the excipient in described imidaclothiz and the MTI-446 compounded pesticides, perhaps be added with the composition of auxiliary agent and excipient;
The invention has the advantages that: utilize thiophene worm piperazine and imidaclothiz and insecticides adjuvant and excipient to be mixed with the agricultural chemicals of different dosage form product according to instructions for use, as water dispersible granules, wetting powder, microemulsion, aqueous emulsion or suspending agent etc.
Above-mentioned auxiliary agent and excipient can be separately and thiophene worm piperazine and imidaclothiz compounded combination use, also can be with the composition and thiophene worm piperazine and the use of imidaclothiz compounded combination of auxiliary agent and excipient.
This insecticide has good preventive effect to the multiple homoptera pest that rice fulgorid, aphid, leafhopper, thrips etc. are easy to generate resistance, and suppresses insect single thiophene worm piperazine and imidaclothiz preparation are developed immunity to drugs, and practical effect is remarkable.
The present invention shows that through a large amount of field trials the existing medicament another kind of medicament different with another kind of mechanism of action is mixed, and can not only postpone resistance and produce, and can also improve drug effect and residual period, thereby reduces usage amount, reduces peasant's dispenser cost.Be embodied in: utilize thiophene worm piperazine and imidaclothiz composite in the hope of reaching the most of sucking pest of effective control, the effect of minimizing environmental pollution improves drug effect and lasting period simultaneously, has reduced peasant's labour cost, has good economic benefit.
