Embodiment 1

[0019] Example 1: Preparation of 26% butylene fipronil·imophos (1:25) wettable powder. By weight percentage, butene fipronil 1% (100% metering, the same below), imophos 25% (100% metering, the same below), dispersant NNO 8%, pull-off powder 10%, white carbon black 8% blended, and then made up to 100% with kaolin, and 26% butene fipronil·imophos wettable powder was prepared according to the above-mentioned conventional blending agent production process.

Embodiment 2

[0020] Example 2: Preparation of 15.5% butylene fipronil·imophos (1:30) wettable powder. Mix 0.5% butylene fipronil, 15% imophos, 3% dispersant NNO, 8% sodium dodecylbenzenesulfonate, and 8% white carbon black according to the yield percentage, and then use light calcium carbonate Make up to 100%, and prepare 15.5% butene fipronil·imophos wettable powder according to the above-mentioned conventional mixture production process.

Embodiment 3

[0021] Example 3: Preparation of 30% butylene fipronil·imophos (1:5) wettable powder. 5% butylene fipronil, 25% imidophos, 8% sodium dodecylbenzenesulfonate, 8% diffusing agent NNO, 3% pull-off powder, and 8% diatomaceous earth were formulated by weight percentage, and then Make up to 100% with kaolin, and prepare 30% butene fipronil·imophos wettable powder according to the above-mentioned conventional compounding agent production process.

Abstract

The invention relates to a pesticidal composition containing butene-fipronil and phosmet, which comprises the following components by weight percent: 0.5-18% of butene-fipronil, 2-72% of phosmet, and 10-97.5% of auxiliary component. The invention has the following advantages: 1. after the butene-fipronil and the phosmet are compounded, the pesticidal composition has obvious synergy function; 2. the pesticidal spectrum is enlarged, and the pesticidal composition has higher activity to lepidoptera insects of paddy snout moth's larva, vegetable plutella xylostella and the like; 3. the dosage of the pesticidal composition is reduced, the pesticide residue on the crop is lowered, and the environmental pollution is reduced; 4. and the pesticidal composition is safe to people and livestock, and is compatible with the environment, and the pesticidal composition can not make injurious insects produce pesticide resistance.

Description

technical field [0001] The invention belongs to pesticides and insecticides, in particular to an insecticidal composition containing butene-fipronil and imophos. Background technique [0002] Crops are harmed by various pests during the production process, and sometimes multiple pests occur at the same time, especially Lepidoptera pests such as stem borers (semi-striped borers, three-spotted stem borers, rice leaf rollers), diamondback moths, cutworms, Rice planthoppers occur year after year, causing great losses to agricultural production. Therefore, pest control is imperative and imminent. However, the most likely problems in the process of pest control are: the repeated use of pesticides leads to increasing pressure on pest resistance, the gradual increase in the amount of control chemicals, and the aggravation of explosive damage. Farmers are hard to prevent. For example, the butylene fipronil used by farmers has a chemical name: 3-fluoro-5-methallylamino-1-(2·6-dichlor...
