Problems solved by technology

However, tricyclazole has a major deficiency: it only has a protective effect, without any therapeutic effect, that is, it can only be used before the rice blast infection occurs.
[0012] At present, most of the granules used in China are single insecticidal or bactericidal ingredients, which cannot effectively treat both diseases and insect pests, which is time-consuming and labor-intensive. Moreover, most of the active ingredients have little regulating effect on crops, and the crops have weak growth and disease resistance.
In order to solve the problems of heavy pesticide application work in paddy fields, single action of granules in preventing and controlling pests and diseases, narrow control spectrum, need for repeated application, small regulating effect on crops, and weak disease resistance of crops, the inventors developed a methoxy Insecticidal and fungicidal composition of tebufenozide

Embodiment 1

[0049] Example 1: Preparation of 18% methoxyfenozide allylbenthiazole emulsifiable concentrate (active ingredient ratio 8:1)

[0050] Weigh 4% Nongru 500#, 2% Nongru 600#, 3% Nongru 2201#, 1% triphenyl phosphite, 2% dimethyl sulfoxide, and cyclohexanone to 100% by weight. The above raw materials are mixed, stirred and dissolved, and then 16% methoxyfenozide and 2% allylbendazole are added, and after stirring and dissolving completely, 18% methoxyfenozide-albendazole emulsifiable concentrate is obtained.

Embodiment 2

[0051] Example 2: Preparation of 8% methoxyfenozide allylbenthiazole suspension (active ingredient 3:1)

[0052] Weigh 6% methoxyfenozide, 2% allylbenzothiazole, 2.5% tristyrylphenol polyoxyethylene ether phosphate, 1.5% diffusing agent NNO, 4% TERSPERSE4894 (produced by Huntsman, USA), 10% cyclohexanone, 3.5% Span-60#, 3.5% Tween-60#, 1% TERSPERSE2500 (produced by Huntsman, USA), 2% magnesium aluminum silicate, 0.2% xanthan gum, 5% ethyl alcohol Diol, 1% epichlorohydrin, 0.3% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), and deionized water are added to 100% by weight. The operation steps are as follows: According to the above ratio, mix and shear the dispersant, wetting agent, defoamer, water, etc. evenly, then add methoxyfenozide and allylbenzothiazole, and grind with a sand mill to obtain 8% Methoxyfenozide Allylbenzothiazole Suspension Concentrate.

Embodiment 3

[0053] Example 3: Preparation of 18% methoxyfenozide allylbenthiazole granule (active ingredient 8:1)

[0054] Weigh 16% methoxyfenozide, 2% allylbenzothiazole, 0.9% alkylnaphthalene sulfonate formaldehyde condensate, 2% polyvinyl alcohol, 1% sodium sulfate, 5% polyethylene glycol , 0.1% polyvinyl alcohol, kaolin as a carrier added to 100%. The above ingredients are kneaded with water, kneaded and shaped by a kneading granulator, and then the granules are dried in a fluidized bed to adjust the particle size to obtain 18% methoxyfenozide allylbenthiazole granules.

Abstract

The invention relates to an insecticide and sterilization composition containing methoxyfenozide. The insecticide and sterilization composition is characterized by being prepared from a first active ingredient (methoxyfenozide) and a second active ingredient selected from probenazole, tiadinil, isoprothiolane or tricyclazole at a mass ratio of (10:1) to (1:10), preferably (3:1) to (1:3). Compared with a single preparation, the insecticide and sterilization composition has an obvious synergistic effect on treatment of plant diseases and insect pests such as chilo suppressalis, rice leaf folder and rice blast, is convenient to apply and long in duration, and is safe and environmentally friendly.

Description

【Technical field】 [0001] The invention belongs to the field of pesticide compositions. More specifically, the present invention relates to an insecticidal and fungicidal composition containing methoxyfenozide, and an insecticidal and fungicide containing the insecticidal and fungicidal composition, as well as the insecticidal and fungicidal composition and the insecticidal The application of fungicides in the control of rice borer, rice leaf roller and rice blast. 【Background technique】 [0002] Chilo suppressalis (Walker) belongs to the order Lepidoptera, Mothidae. It is one of the most serious and frequent pests of rice in China. It is distributed in all rice areas in China, but mainly in the Yangtze River Basin and the rice areas south of it. occur heavier. Damaged at the tillering stage causes withered sheaths and seedlings, and damages at the ear stage cause insect damage to plants and white ears. In general, the yield is reduced by 3% to 5%, and in severe cases, the ...
