example 1

[0038] Bioassay example 1: Toxicity determination of indoxacarb and thiodicarb complex against beet armyworm

[0039] Test object: resistant beet armyworm larvae (resistance to lambda-cyhalothrin is more than 500 times as measured by drug resistance)

[0040] 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 ...

Embodiment 1

[0053] Example 1: 11% indoxacarb · Bacillus thuringiensis wettable powder

[0054]

[0055] The active ingredients, various auxiliary agents, etc. are fully mixed according to the ratio of the formula, and after being pulverized by a superfine pulverizer, the 11% indoxacarb·Bacillus thuringiensis wettable powder can be obtained.

[0056] The Bacillus thuringiensis in this example can be replaced by veratridine, thiodicarb, Daofengsan, and deltamethrin, and a new example can be formed according to the same method and formula ratio.

[0057] The 11% indoxacarb·Bacillus thuringiensis wettable powder prepared in Example 1 was used to control cabbage caterpillar. The 11% indoxacarb·Bacillus thuringiensis wettable powder was diluted 3000 times with water and sprayed, and the control effects were 83.7%, 96.8% and 92.5% at 1 day, 7 days and 15 days after the application. 150g / L indoxacarb suspension was used at 3500 times and 2% Bacillus thuringiensis wettable powder at 1000 times...

Embodiment 2

[0058] Example 2: 30% indoxacarb · Bacillus thuringiensis suspension

[0059]

[0060] Mix the active ingredient, dispersant, wetting agent, antifreeze agent, thickener, defoamer and water according to the proportion of the formula, and grind it with a sand mill to obtain 30% indoxacarb·Bacillus thuringiensis suspension agent.

[0061] The Bacillus thuringiensis in this example can be replaced by veratridine, thiodicarb, Daofengsan, and deltamethrin, and a new example can be formed according to the same conditions and formula ratio.

[0062] The indoxacarb-Bacillus thuringiensis suspension concentrate prepared in Example 2 was applied to control rice leaf roller. The 30% indoxacarb·Bacillus thuringiensis suspension was diluted 5000 times with water and sprayed, and the control effects were 97.6% and 95.3% 7 days and 15 days after the application. 150g / L indoxacarb suspension was used at 3500 times and 2% Bacillus thuringiensis wettable powder at 1000 times, using the same...

Abstract

The invention discloses an indoxacarb-containing complex pesticide composition. The composition comprises components of a component I and a component II, the component I is indoxacarb, the component II is Bacillus thuringiensis, veratridine, thiodicarb, phenthoate or deltamethrin, and the mass ratio of the component I to the component II is 10:1-1:50. The invention also discloses a dosage form of a preparation which is prepared from the composition and is suitable for agricultural use, and an application of the composition in crop pest control. The indoxacarb-containing complex pesticide composition of the invention, which has an obvious synergistic effect, can be used for the pest control on crops of fruit trees, cotton, paddy rice, vegetables and the like, and especially has a substantial control effect on lepidoptera pests.

Description

technical field [0001] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing indoxacarb. Background technique [0002] In recent years, due to single and unscientific use of drugs, many pests have developed resistance to the currently used pesticides, such as diamondback moth, cotton bollworm, etc., which has become a major problem in the chemical control of pests. [0003] Indoxacarb is a new type of oxadiazine insecticide. Its insecticidal mechanism is to block the sodium ion channel in the nerve cells of the pests, so that the nerve cells of the pests lose their function and are paralyzed, their coordination ability is reduced, and they eventually die. The medicament works by contacting or feeding into the insect body, and there is no cross-resistance with other insecticides. It has high activity against pests of agricultural and horticultural crops such as vegetables, sugar beets, cotton, fruit trees...
