Embodiment 1

[0015] Example 1: 41% spirotetramat · diafenthiuron wettable powder (spirotetramat: diafenthiuron=40:1)

[0016] Spirotetramat 41.67g, diafenthiuron 1.03g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin to make up to 100g.

[0017] The active ingredient spirotetramat and diafenthiuron, various additives and fillers are fully mixed in proportion, and pulverized by an ultrafine pulverizer to obtain a wettable powder.

Embodiment 2

[0018] Example 2: 21% spirotetramat·lufenuron suspension concentrate (spirotetramat: diafenthiuron=20:1)

[0019] Spirotetramat 20.83g, lufenuron 1.04g, lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, silicone oil (defoamer) 0.4g , supplemented with deionized water to 100g.

[0020] 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

[0021] Example 3: 11%% spirotetramat · diafenthiuron EC (spirotetramat: diafenthiuron=10:1)

[0022] Spirotetramat 10.42g, diafenthiuron 1.03g, N-methylpyrrolidone (solvent) 10g, epichlorohydrin (stabilizer) 3g, calcium dodecylbenzenesulfonate (emulsifier) ​​5g, styrene Base phenol polyoxyethylene ether (emulsifier) ​​5g, dichloromethane (solvent) make up to 100g.

[0023] Add the original drug, 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 comprising the effective components of screw worm ethyl and another insecticidal active component (B), wherein the mass ratio of the screw worm ethyl and the B is 40:1-1:80. In the invention, the insecticidal active component B is one of diafenthiuron and lufenuron. The screw worm ethyl and the diafenthiuron or the lufenuron are compounded, havean obvious synergistic action, can reduce the use quantity of effective components and expand prevention and treatment spectra. The composition can be used for preventing and treating various pests inagriculture and is especially suitable for preventing and treating pests with sucking mouth parts, such as aphides, whiteflies, thrips, plant hoppers, leafhoppers and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal composition containing spirotetramat as an active ingredient, and the application of the composition in the control of agricultural pests. Background technique [0002] Spirotetramat (Spirotetramat) is a tetronic acid insecticide. Spirotetramat has two-way systemic conduction properties, and can move up and down in 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] Diafenthiuron is a new type of thiourea high-efficiency insecticide and acaricide, which has contact killing,...
