Example Embodiment

[0021] Example 1: Indoor joint virulence determination of diamondback moths in a mixed pair of butafenil and diflubenzuron.

[0022] The test agent used 96% butaprofen technical and 95% chlorflubenzuron technical.

[0023] Put the larvae of Plutella xylostella collected in the field into the prepared cabbage seedlings. After the larvae are pupated, collect the pupae in a petri dish with moisturizing filter paper, put them in the spawning cage and let them emerge, and then put the whole dish of cabbage Put the seedlings in the spawning cage for the diamondback moth larvae to lay eggs. When the amount of eggs laid on each plate of cabbage seedlings reaches about 500, take out the cabbage seedling plates and place them in the artificial climate box [temperature: 24-26℃; relative humidity 70%- 80%; light: 14(L):10(D)], let the eggs hatch and raise them to the third instar larvae.

[0024] The poisoning leaf method is adopted for the determination: the leaf butterfly is punched out with ...

Example Embodiment

[0029] Example two :The preparation method of butaprofen and benzoyl urea insecticide composition

Example Embodiment

[0030] Preparation method embodiment 1: 20% butafenil·diflubenzuron wettable powder,

[0031] Butaprofen 2%,

[0032] Mechlorfenuron 18%,

[0033] Sodium dodecylbenzene sulfonate (wetting agent) 5%,

[0034] Sodium lignosulfonate (dispersant) 8%,

[0035] Talc (filler) 3%,

[0036] White carbon black (filler) 4%,

[0037] Attapulgite (filler) is added to 100%.

[0038] The above-mentioned materials are roughly pulverized in proportion and then mixed uniformly in a mixer, and then pulverized by air flow to obtain 20% butafenil·diflubenzuron wettable powder.

Abstract

The invention discloses a pesticide composition with flufiprole and benzoylurea insecticide. The effective components are flufiprole and benzoylurea insecticide, the benzoylurea insecticide is one of chlorbenzuron, hexaflumuron and chlorfluazuron, the weight ratio of the flufiprole to benzoylurea insecticide is (1:20)-(20:1), the weight percentage of the weight summation of the flufiprole and the benzoylurea insecticide in the composition is 2-80%. The pesticide composition disclosed by the invention is used for preventing and controlling vegetable plutella xylostella. The preventing and controlling effect of the pesticide composition is obviously improved in comparison with that of a single agent, the use dosage of the pesticide is lowered, the influence on the environment caused by the pesticide is reduced, and the drug use cost is lowered.

Description

technical field [0001] The invention relates to a pesticide composition, which is used for preventing and controlling vegetable diamondback moth by using tripronil and benzoylurea insecticides as active ingredients. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable development of agriculture. Therefore, the research and development of high-efficiency, low-toxicity...
