Problems solved by technology

However, because it is not friendly to the environment, it has high risks to crustacean aquatic organisms and bees, and it degrades slowly in water and soil. Prohibition and restricted use, except for hygienic, corn and other upland seed coating agents and products specially for export, stop accepting and approving field trials and pesticide registrations (including official registrations, temporary registrations) of other pesticide formulations containing fipronil registration, repackaging registration) and production approval certificates, and revoke the approved registration and production approval certificates

Embodiment Construction

[0015] Further description will be given below in conjunction with specific examples.

[0016] Experiment 1: Indoor Toxicity Assay

[0017] 1. Drugs to be tested

[0018] 98.2% buprofezin technical, Jiangsu Changlong Chemical Co., Ltd.; 90% butene fipronil technical, provided by Dalian Ruize Pesticide Co., Ltd.

[0019] 2. Source of tested insects

[0020] The white-backed planthoppers were collected from Daliu Village, Hongze County, Jiangsu Province in 2015, and were raised with indica rice for one generation without contacting any pesticides indoors. The feeding temperature is 25±1°C, and the photoperiod is 16 / 8h (L / D). The mid-3rd instar nymphs were used for determination.

[0021] 3. Single dose assay method

[0022] The sensitivity of white-backed planthoppers to insecticides was determined using the method established by Zhuang Yonglin et al., i.e. the rice stem dipping method: the robust rice stems from the tillering stage to the booting stage were pulled out by t...

Abstract

The invention discloses a compound insecticide of butene-fipronil and buprofezin. The compound insecticide consists of pesticide active ingredients butene-fipronil and buprofezin at a ratio of (1:20)-(1:5). The cotoxicity coefficient of the compound insecticide is as high as 141.569-303.595. The compound insecticide has a certain synergism effect, is an efficient, low-toxin and economic compounded preparation, is high in toxicity to insects such as hemiptera and homoptera such as rice planthopper, is good in fast-acting property and persistent effect, is small in damage to the environment and non-target organisms and is relatively low in use cost, and the control efficiency is greater than 85% 3 days, 7 days and 14 days later after the compound insecticide is used.

Description

technical field [0001] The invention relates to the technical field of compound pesticides, in particular to a compound insecticide of butene-fipronil and buprofezin. Background technique [0002] Butene fipronil, 3-cyano-5-methallylamino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylsulfinylpyridine Azole is a new compound developed by Dalian Ruize Pesticide Co., Ltd. on the basis of fipronil. Butene fipronil has high activity against many pests such as rice planthopper, cabbage caterpillar, diamondback moth, stem borer, leaf beetle, etc., and especially has the same activity as fipronil against pests on rice, vegetables and other crops. At the same time, because the agent has low toxicity to fish, it opens up a wider space for its application in rice and vegetables. [0003] Buprofezin is a growth regulator that inhibits the synthesis of chitin in the cuticle of insects. It has high contact and stomach toxicity, and will cause insects to die during the moulti...
