Embodiment 1

[0018] Bioassay Example 1 : Indoor joint toxicity test of the combination of tripronil and isoprocarb against rice planthopper.

[0019] According to the known indoor breeding method of rice planthoppers, the brown planthoppers collected in the field were reared to the second generation and third instar nymphs.

[0020] First dissolve 96% of the original drug of fenpronil and 98% of the original drug of isoprocarb with acetone, and then dilute it into 6 series of single doses and combination concentration gradients. The drop method recommended by NY / T 1154.1-2006 is used for measurement, the micro dropper is cleaned with solvent, and the dropper is adjusted to the standby state. Use a brush to select neat and consistent test insects and use CO 2 After mild anesthesia, place it in a 9cm petri dish, and then use a micro-dropper to drip the drug on the abdomen of the test insect head by head, with 0.1ul of the drug solution per head, and a treatment containing 0.1ul of the corr...

Embodiment 2

[0036] Preparation method embodiment 2 : 25% tripronil · Zhongbucarb microemulsion:

[0037] Methpronil 3%,

[0038] Zhongdingwei 22%,

[0039] 602 (emulsifier) ​​8%,

[0040] NP-10 (emulsifier) ​​5%,

[0041] Cyclohexanone 5%,

[0042] Xylene 5%,

[0043] Deionized water Make up to 100%.

[0044] Add the above formula into the reaction kettle in proportion, mix and stir evenly, and finally add deionized water fully and uniformly to prepare a 25% chlorfenapyr-sec-butacarb microemulsion.

Embodiment 3

[0045] Preparation method embodiment 3 : 22% tetraprole Carbaryl Suspending Concentrate:

[0046] Niprole 2%,

[0047]Carbaryl 20%,

[0048] Nongru 1601# (emulsifier) ​​10%,

[0049] Soybean oil (organic solvent) 5%,

[0050] Tristyrylphenol polyoxyethylene polyoxypropylene ether (wetting agent) 5%,

[0051] Alkylphenol polyoxyethylene ether formaldehyde condensate sulfate (dispersant) 4%,

[0052] Bentonite (thickener) 3%,

[0053] Xanthan gum (stabilizer) 0.3%,

[0054] Silicone (defoamer) 0.3%,

[0055] Alkyl polyglucoside (surfactant) 5%,

[0056] Deionized water (medium) replenished to 100%.

[0057] The above-mentioned materials were pre-crushed in proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 22% tetraprole-carbaryl suspension concentrate.

Abstract

The invention discloses a synergistic pesticide composition and application thereof. The active components of the synergistic pesticide composition are flufiprole and carbamate pesticide, wherein the carbamate pesticide is one of fenobucarb, isoprocarb, carbosulfan, carbaryl, metolcarb, methomyl, pirimicarb and thiodicarb. The weight ratio of the flufiprole to the carbamate pesticide is (1:50) - (1:1), and the weight percentages of the flufiprole and the carbamate pesticide in the composition are both 2-80%. The synergistic pesticide composition is applied to preventing and controlling agricultural pests. Through the application of the synergistic pesticide composition, the control efficiency is obviously improved as compared with that of single dosage, the use amount of the pesticide is reduced, the influence of pesticide on environment is reduced, and the pesticide cost is lowered.

Description

technical field [0001] The invention relates to a pesticide composition, which uses tripronil and carbamate insecticides as active ingredients to prevent and control rice planthoppers. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable development of agriculture. Therefore, the research and development of high-efficiency, low-toxicity, and environmental-friendly in...
