example 1

[0015] Bioassay example 1: Toxicity determination of lufenuron and diafenthiuron against Spodoptera litura

[0016] Test object: Spodoptera litura, egg masses collected in the field, hatched indoors and reared to third instar larvae

[0017] 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 disks, 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, with each hole 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 26-27 ℃ constant temperature room for rearing in the dark, and observe the results after 72 hours. The standard of death was to lightly touch the wo...

Embodiment 1

[0043] Example 1: 30% Lufenuron·Diafenthiuron EC

[0044] Lufenuron 5%

[0045] Diafenthiuron 25%

[0046] N-methylpyrrolidone (solvent) 10%

[0047] DMF (solvent) 10%

[0048] Nongru 1601# (emulsifier) ​​5%

[0049] Nongru 500# (emulsifier) ​​5%

[0050] Xylene (solvent) was made up to 100%.

[0051] The active ingredient, emulsifier and solubilizing agent are sequentially added into the mixing kettle according to the proportion of the formula, and stirred evenly to prepare 30% lufenuron·diafenthiuron emulsifiable concentrate.

[0052]This embodiment is applied to the control of Spodoptera litura on soybean. 30% Lufenuron·Diafenthiuron EC was diluted and sprayed with 4 g / mu of active ingredients and water, and the control effects were 65.2%, 93.3%, and 92.8% on 2 days, 5 days, and 10 days after application. 5% lufenuron 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 ...

Abstract

The invention relates to a pesticide composition, and the effective components thereof are lufenuron and diafenthiuron, wherein the mass ratio of the lufenuron to the diafenthiuron is 5:1-1:40. The pesticide composition of the invention has obvious synergy to diamond back moth, spodoptera litura and cabbage caterpillar and the like, and also has favorable effect on preventing and treating other pests and mites on crops such as vegetable, fruit trees, cotton, soybean and tobacco. In comparison with single preparation, the dosage is reduced and the effect is improved, and the composition is helpful for the development of delaying the drug resistance of pests.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal and acaricidal compound composition containing lufenuron. 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, with the enhancement of people's awareness of safety and environmental protection, the difficulty of developing new pesticides has greatly increased. 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] Lufenuron (Lufenuron), the chemical name is N-[[[2,5-dichloro-4-(1,1,2,3,...
