Embodiment 1

[0014] Example 1: 41% spirotetramat bifenthrin wettable powder (spirotetramat: bifenthrin=40:1)

[0015] Spirotetramat 41.67g, bifenthrin 1.03g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin to make up to 100g.

[0016] The active ingredients spirotetramat and bifenthrin, various additives and fillers are fully mixed in proportion, and the wettable powder is obtained after being pulverized by an ultrafine pulverizer.

Embodiment 2

[0017] Embodiment 2: 21% spirotetramat · bifenthrin suspension concentrate (spirotetramat: bifenthrin=20:1)

[0018] Spirotetramat 20.83g, bifenthrin 1.03g, lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, silicone oil (defoamer) 0.4 g, replenished to 100g with deionized water.

[0019] Add the pre-crushed original medicine and carrier, dispersant, defoamer, thickener, etc. into a sand mill, grind it finely, and then mix it through high-speed shearing to obtain a suspension.

Embodiment 3

[0020] Example 3: 11% spirotetramat Bifenthrin EC (spirotetramat: bifenthrin=10:1)

[0021] Spirotetramat 10.42g, bifenthrin 1.03g, N-methylpyrrolidone (solvent) 10g, epichlorohydrin (stabilizer) 3g, calcium dodecylbenzenesulfonate (emulsifier) ​​5g, benzene Ethylphenol polyoxyethylene ether (emulsifier) ​​5g, dichloromethane (solvent) make up to 100g.

[0022] Add the original drug containing active ingredients, emulsifier and co-solvent, etc., according to the proportion of the formula, into the mixing tank, and stir evenly to obtain the emulsifiable concentrate.

Abstract

The invention discloses an insecticidal composition. The active ingredients of the composition comprise spirotetramat and bifenthrin in a mass ratio of 40:1 to 1:80. The compounding of spirotetramat and the bifenthrin produces an obvious synergistic effect and can reduce the dosage of the active ingredients and medicament application times and delay the generation of pesticide resistance of pests. The insecticidal composition can be used for preventing and controlling various pests on agricultural crops and garden crops, particularly plant hoppers, leafhopper and whitefly.

Description

technical field [0001] The invention relates to an insecticidal composition, specifically a pesticide composition containing spirotetramat, and the application of the composition in the control of agricultural pests. Background technique [0002] Spirotetramat (Spirotetramat) is a tetronic acid insecticide. Spirotetramat has a unique mechanism of action, which can move up and down the whole plant to reach the leaves and bark, so as to control pests such as lettuce and cabbage inner leaves and fruit bark. Spirotetramat is highly efficient and broad-spectrum, and can effectively control various piercing-sucking mouthpart pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects. However, if spirotetramat is used alone, it is easy to make pests resistant, and the cost of control is relatively high. [0003] Bifenthrin is a pyrethroid insecticide, which has contact and stomach poisoning effects, as well as repellent and antifeedant effects, and is widely...
