Pesticide composition

A technology for pesticide compositions and active ingredients, which is applied in the directions of animal repellents, plant growth regulators, botanical equipment and methods, etc., can solve the problem of not keeping up with the speed of pest resistance, unsatisfactory chemical control effect, and development of active ingredients. The problem of high cost is to achieve the effect of improving the control effect, delaying the development and delaying the drug resistance.

Problems solved by technology

In recent years, pests have developed strong resistance to pesticides, and the control effect of conventional pesticides has been very unsatisfactory.
[0005] For the prevention and control of resistant pests in agriculture, one way is to introduce new ingredients that have no cross-resistance with existing varieties, but the

Example Embodiment

[0027] Example 1: Toxicity test of cyfluthron, abamectin and emamectin benzoate compound

[0028] 1. Cyanoflurzone, abamectin and different ratios to determine the toxicity of Cnaphalocrocis medinalis

[0029] The pupae of Cnaphalocrocis medinalis were collected from the field and raised indoors for three generations. The third instar larvae with uniform growth were selected as the test insects in this experiment. Using the leaf-dipping method, the test agent was mixed with acetone and 10% soil temperature-80 to prepare a certain concentration of mother liquor, and then diluted with clear water to 5 gradient concentrations for later use, and set clear water as a control. Take fresh rice leaves and cut them into approximately 50mm long pieces of the same size, soak the cut leaves in the prepared test solution for 10 seconds, take them out and let them dry naturally, and put them in the ones with filter paper beforehand. In a petri dish (φ120mm). Then, the 3rd instar larvae of Cnap...

Example Embodiment

[0050] Example 2: Preparation method of 80.5% cyanflurane·avermectin EC

[0051] Cyhalazone 80%

[0052] Abamectin 0.5%

[0053] Nongru 600# (emulsifier) ​​8%

[0054] Xylene (solvent) balance

[0055] According to the requirements of the formula, mix and stir the cyanflurane, abamectin, emulsifier, and part of the solvent in the preparation kettle. After it is completely dissolved, slowly add the remaining solvent, and a uniform oil phase is obtained after thorough stirring. After sampling and testing are qualified, the pesticide composition emulsifiable concentrate of the present invention is prepared.

[0056] Example 3: Preparation method of 41% cyfluridzone·abamectin suspension

[0057] Cyhalazone 40%

[0058] Abamectin 1%

[0059] Sodium dodecylbenzene sulfonate (wetting agent) 1%

[0060] Calcium lignosulfonate (dispersant) 2%

[0061] Methyl cellulose (tackifier) ​​2%

[0062] Bentonite (stabilizer) 3%

[0063] Ethylene glycol (antifreeze) 1%

[0064] Deionized water (solvent) balance

[0065] According to the requirements of the formula, in a dispersion tank equipped with a high-speed stirrer, disperse the original drug and dispersant in water to coarsely pulverize the original drug; the coarsely pulverized solution is continuously fed into the sand mill with a quantitative pump. Carry out fine pulverization; the solution separated and discharged from the medium is sent to the final mixing tank, and the separately prepared thickener solution is added to the final mixing tank, and the pulverized solution is evenly mixed to obtain a suspension. After sampling and analysis are qualifi...

Abstract

The invention discloses a pesticide composition. Effective components of the pesticide composition include a component A and a component B, wherein the component A is metaflumizone, the component B is any of abamectin and emamectin benzoate, and the weight ratio of the component A and the component B is 160:1-1:40. The composition has the advantage that the composition can be used for preventing and killing obviously resistant pests, in particular for preventing and killing resistant diamond back moth, spodoptera exigua and cnaphalocrocis medinalis.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing metaflumizone, which is used to prevent and control resistant pests on crops. Background technique [0002] In agricultural production, chemical control is an important means of preventing and controlling crop diseases and insect pests. In the process of chemical control, due to the long-term and irrational use of chemical pesticides, the resistance of pests and germs has been increasing, which has brought great difficulties to the control work. [0003] Plutella xylostella is a major pest of cruciferous vegetables. In recent years, the resistance of Plutella xylostella has developed rapidly, so that many effective insecticides have successively weakened the control effect. Huazhong Agricultural University measured in 2005 and found that the resistance of Guangdong Plutella xylostella population to abamectin has reached 30 times, reaching a medium le...
