Example Embodiment

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

[0039] Test object: Resistant Spodoptera exigua larvae (The resistance to lambda-cyhalothrin is more than 500 times tested by resistance)

[0040] Test method: Refer to the guidelines for the indoor bioassay of insecticides and pesticides "The People's Republic of China Agricultural Industry Standard NY / T 1154.7-2006" and the creation of the pesticide biological activity evaluation SOP (Insecticide Roll), using the spray method. Select third-instar larvae that grow uniformly and connect them to a 9 cm diameter petri dish containing 10 grams of fresh artificial feed, 10 larvae per dish, 5 dishes per treatment, and spray with a Potter spray tower at 50 PSI. Spray one dish at a time, spray 1 ml of liquid medicine per dish, and spray the same amount of water for the blank control. Generally, 6 concentration gradients are set for each treatment. Put the treated petri dish into a 25°C...

Example Embodiment

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

[0054]

[0055] The effective ingredients, various auxiliary agents, etc. are fully mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, 11% indoxacarb·Bacillus thuringiensis wettable powder is obtained.

[0056] The Bacillus thuringiensis in this embodiment can be replaced with veratrine, thiodicarb, rice phoenix, and deltamethrin, and a new embodiment is formed according to the same method and formula ratio.

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

Example Embodiment

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

[0059]

[0060] The active ingredients, dispersant, wetting agent, antifreeze, thickener, defoamer and water are mixed uniformly according to the proportion of the formula, and then ground by a sand mill to obtain 30% indoxacarb·Bacillus thuringiensis suspension Agent.

[0061] The Bacillus thuringiensis in this embodiment can be replaced with veratrine, thiodicarb, rice phosgene, and deltamethrin, and a new embodiment is formed under the same conditions and formula ratio.

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

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...
