example 1

[0033]Biological Assay Example 1: Toxicity determination of difenfluramide and diafenthiuron compound against Spodoptera litura

[0034] Test object: Spodoptera litura combined with diafenthiuron, egg masses collected in the field, hatched indoors and reared to the third instar larvae

[0035] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". Use a hole puncher with a diameter of 1cm to punch fresh cabbage leaves into leaf butterflies, soak them in the prepared medicinal solution for 10 seconds, take them out, put them on absorbent paper to dry, and then put them into a twenty-four-well plate. Put a leaf dish; use a small brush to pick Spodoptera litura into a 24-well plate, put one worm in each hole, cover with double-layer absorbent paper, and then cover the lid; repeat each treatment three times; put the 24-well plate in 26 The -27°C constant temperature room was kept away from light, and the results were observed after 72 s...

Embodiment 1

[0060] Example 1: 30% diflufluxuron. diafenthiuron EC

[0061]

[0062] The active ingredient, emulsifier and co-solvent are sequentially added into the mixing tank according to the proportion of the formula, and stirred evenly to prepare 30% diflufenuron-diafenthiuron emulsifiable concentrate.

[0063] This embodiment is applied to the control of Spodoptera litura on soybean. Dilute and spray 30% diflufenuron diafenthiuron emulsifiable concentrate with 4 g / mu of active ingredient and add water, and the control effects after 2 days, 5 days and 10 days are 65.2%, 93.3% and 94.8% respectively. 5% diflufenuron EC and 25% diafenthiuron EC were used in the same way according to the doses of 4 g / mu and 20 g / mu of active ingredients respectively, and the control effects were 51.2%, 38.9%, and The control effects of 5 days and 10 days were 82.3%, 84.1% and 73.4%, 74.1%, respectively. The synergistic effect of compounding diafenthiuron and diafenthiuron is obvious, and the control...

Embodiment 2

[0064] Example 2: 41% diflufenuron-diafenthiuron suspension concentrate

[0065]

[0066] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the ratio of the formula, and after grinding and / or high-speed shearing, a 41% diflufenuron-diafenthiuron suspension concentrate is obtained.

[0067] This embodiment is applied to control Plutella xylostella, and a safety test is carried out, and the application period of the test is the cabbage seedling stage (4-5 leaf stage). Dilute and spray 41% difenfluramide-diafenthiuron suspension concentrate at 5 g / mu with water, and the control effect reaches 92.5% within 3 days after application. 5% diflufenuron EC and 50% diafenthiuron SC were used in the same way according to the active ingredient doses of 5 g / mu and 20 g / mu respectively, and the control effects were 87.1% and 71.3% respectively after 3 days of application.

[0068] The safety of cabbage seedlings was observed 3 days ...

Abstract

The invention discloses a synergistic insecticide composition taking novaluron and diafenthiuron as main active ingredients and application thereof. The novaluron and the diafenthiuron are used as the main active ingredients of the composition, and the weight ratio of the novaluron to the diafenthiuron is 5:1-1:4. The insecticide composition disclosed by the invention has an obvious synergistic effect on plutella xylostella, spodoptera litura, cabbage caterpillar and the like, and has good prevention and treatment effects on other injurious insects and mites on crops of vegetables, fruit trees, cotton, soybeans, tobacco and the like. Compared with a single preparation, the dosage of the composition is reduced, and the effect is improved, which is conductive to delaying the development of the drug resistance of injurious insects.

Description

technical field [0001] The invention belongs to the pesticide composition, in particular to a synergistic insecticide composition containing diflufenuron and diafenthiuron as main active ingredients and an application thereof. Background technique [0002] In recent years, due to single and unscientific use of drugs, many pests have developed resistance to the currently used pesticides, especially on some Lepidoptera pests such as diamondback moth, Spodoptera litura, cotton bollworm, beet armyworm, etc., commonly used The control effect of chemicals is difficult to meet the ideal control requirements. On the other hand, as people's awareness of safety and environmental protection increases, and the difficulty of developing new pesticides increases greatly, how to scientifically use existing pesticide varieties, delay the occurrence and development of pest resistance, and prolong the service life of pesticides is an urgent problem to be solved. . [0003] Diflufluramide bel...
