example 1

[0044] Bioassay Example 1: Toxicity determination of spirodiclofen and indoxacarb compound on beet armyworm and spider mite

[0045] Test subjects: Resistant beet armyworm and spider mite

[0046] Test method: Refer to the Indoor Bioassay Test Guidelines for Insecticides and Pesticides "The People's Republic of China Agricultural Industry Standard NY / T 1154.7-2006" and the creation of the SOP for the evaluation of biological activity of pesticides (Pesticide Volume), using the spray method. Select the third instar larvae with uniform growth, insert into a 9 cm petri dish with a diameter of 10 grams of fresh artificial feed, connect 10 per dish, and connect 5 dishes per treatment, spray under 50PSI pressure with a PottER spray tower, every Spray one dish at a time, each dish is sprayed with 1 ml of liquid medicine, and the blank control is sprayed with the same amount of water. Generally, 6 concentration gradients are set for each treatment. Put the treated petri dish into 25...

Embodiment 1

[0059] Example 1: 41% spirodiclofen · indoxacarb wettable powder

[0060]

[0061] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by a superfine pulverizer, the 41% spirodiclofen·indoxacarb wettable powder can be obtained.

[0062] Indoxacarb in this example can be replaced by chlorantraniliprole, tofenpyramide, fenfluzide, trifluroxyfen, flubendiamide or chlorfluazuron, and form a new the embodiment.

[0063] The 41% spirodiclofen·indoxacarb wettable powder prepared in Example 1 was applied to control cotton bollworm and spider mite. The 41% spirodiclofen·indoxacarb wettable powder was diluted 4000 times with water and sprayed, and the control effects on cotton bollworm and spider mite were 83.5%, 93.2%, 90.2% and 87.2% on 1 day, 7 days and 15 days after spraying. %, 97.1%, 93.5%. 240g / L spirodiclofen suspending agent is 3000 times and 150g / L indoxacarb suspending agent is 2500 t...

Embodiment 2

[0064] Example 2: 21% Spirodiclofen·Cenfenozide Suspending Concentrate

[0065]

[0066]

[0067] Mix the active ingredient, dispersant, wetting agent, antifreeze agent, thickener, defoamer and water according to the ratio of the formula, and grind it with a sand mill to obtain 21% spirodiclofen-cyclamethylene Hydrazine suspension.

[0068]In this example, fenflufenozide can be replaced by indoxacarb, chlorantraniliprole, tolfenpyramide, fluomepyr, flubendiamide or chlorfluazuron, and a new the embodiment.

[0069] The 21% spirodiclofen-fenfenozide suspension concentrate prepared in Example 2 is used to control wheat armyworm and spider mite. Dilute 21% spirodiclofen·cyclenfenozide suspension concentrate 2500 times with water and spray, and the control effects on armyworm and spider mite are 94.7%, 96.2%, 94.5%, 91.6% 7 days and 15 days after spraying. 240g / L spirodiclofen suspension concentrate was used at 3000 times and 5%% fenfenozide suspension was used at 1000 ti...

Abstract

The invention discloses a spirodiclofen-containing compound pesticidal composition. Effective components of the spirodiclofen-containing compound pesticidal composition comprises a component I and a component II, wherein the component I is spirodiclofen; the component II is one of indoxacarb, chlorantraniliprole, tolfenpyrad, chromafenozide, pyridalyl,flubendiamide and chlorfluazuron; and the mass ratio of the component I to the component II is 40:1-1:40. The invention further discloses a preparation which is prepared from the spirodiclofen-containing compound pesticidal composition and is suitable for agricultural use, and application of the spirodiclofen-containing compound pesticidal composition to pest control of crops. The spirodiclofen-containing compound pesticidal composition has a significant synergistic effect and is applied to the pest control of the crops such as fruit trees, cotton, wheat, vegetables, flower, rice and the like, especially with significant effect on control of lepidopteran pests and mite pests.

Description

technical field [0001] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing spirodiclofen and its preparation. Background technique [0002] In recent years, due to single-use and unscientific use of drugs, many pests have become resistant to the currently used pesticides, especially cabbage caterpillars, diamondback moths, noctuids, cut moths, cabbage borers, armyworms, rice borers, and rice verticals. Lepidopteran pests such as leaf rollers and cotton bollworms, and mite pests such as red spiders and spider mites have become a major problem in chemical pest control. [0003] Spirodiclofen is a new type of tetronic acid acaricide. The mechanism of action of spirodiclofen is to inhibit the fat synthesis in harmful mites, destroy the energy metabolism of mites, and finally kill harmful mites. It has no cross-resistance with existing acaricides and is suitable for controlling harmful mites that are resis...
