example 1

[0045] Bioassay Example 1: Toxicity determination of spirodiclofen and indoxacarb compound on beet armyworm and spider mite

[0046] Test subjects: Resistant beet armyworm and spider mite

[0047] Test method: Refer to the indoor bioassay test guidelines for pesticides and pesticides "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" 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°C,...

Embodiment 1

[0060] Example 1: 41% spirodiclofen · indoxacarb wettable powder

[0061]

[0062] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, 41% spirodiclofen·indoxacarb wettable powder can be obtained.

[0063] Indoxacarb in this example can be replaced by chlorantraniliprole, tofenpyramide, fenfluzide, trifluroxyfen, flubendiamide or chlorfluazuron, and form a new the embodiment.

[0064] 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 and sprayed with water 4000 times, 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 the application. %, 97.1%, 93.5%. 240g / L spirodiclofen suspending agent is 3000 times and 150g / L indoxacarb suspending agent is...

Embodiment 2

[0065] Example 2: 21% Spirodiclofen·Cenfenozide Suspending Concentrate

[0066]

[0067]

[0068]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.

[0069] In this example, fenflufenozide can be replaced by indoxacarb, chlorantraniliprole, tolfenpyramide, fluomepyr, flubendiamide or chlorfluazuron, and a new the embodiment.

[0070] The 21% spirodiclofen-fenfenozide suspension concentrate prepared in Example 2 was used to control wheat armyworm and spider mite. Dilute 21% spirodiclofen · cyclofenozide 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 t...

Abstract

The invention discloses a compound pesticide composition containing spirodiclofen. The effective components comprise 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 also discloses an agriculturally applicable preparation formulation prepared from the composition and application of the composition in preventing and treating crop pests. The compound pesticide containing spirodiclofen has an obvious synergistic action, is used for preventing and treating pests on fruit trees, cotton, wheat, vegetables, flowers, rice and other crops, and especially has an obvious effect on preventing and treating Lepidoptera pests and acarid pests.

Description

[0001] This application is a divisional application of "a compound pesticide composition containing spirodiclofen and its preparation". The filing date of the original application is June 12, 2012, and the application number of the original application is 201210192832.9. technical field [0002] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing spirodiclofen and its preparation. Background technique [0003] 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. [0004] Spirodiclofen is a new type of tetronic acid acaricide. Th...
