Description
技术领域technical field
本发明属于农药领域,具体涉及一种含氯氟氰虫酰胺和氟铃脲的杀虫组合物。The invention belongs to the field of pesticides, in particular to an insecticidal composition containing cyantraniliprole and hexaflumuron.
背景技术Background technique
农业害虫的抗性问题是一个全球性的问题。随着害虫化学防治的的延续、农药使用量的增加以及不科学使用农药,害虫抗性日益严重,产生抗性的害虫种类不断增多。特别是对农业生产为害严重的鳞翅目类害虫,抗性程度较高,抗性发展速度相对较快。同时,高强度的使用农药,导致农产品农药残留超标、环境污染和农民用药成本增加等,不利于农业可持续发展。因此,研究开发高效、低毒、环保的杀虫剂农药对农业可持续发展具有积极意义。The problem of resistance to agricultural pests is a global problem. With the continuation of chemical control of pests, 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. Especially the lepidopteran pests that seriously damage agricultural production have a high degree of resistance and relatively fast development of resistance. 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, and environmental-friendly insecticides and pesticides has positive significance for the sustainable development of agriculture.
氟铃脲(Hexaflumuron)是苯甲酰脲类昆虫生长调节剂,通过抑制昆虫几丁质合成而杀死害虫。具有杀虫活性高、杀虫谱较广、击倒力强等特点。Hexaflumuron is a benzoylurea insect growth regulator that kills pests by inhibiting insect chitin synthesis. It has the characteristics of high insecticidal activity, wide insecticidal spectrum and strong knockdown power.
氯氟氰虫酰胺是浙江省化工研究院自行研制的新型杀虫剂,代号ZJ4042,化学名称为:3-氯-N1-(2-甲基-4-七氟异丙基苯基)-N2-(1-甲基-1-氰基乙基)邻苯二甲酰胺,结构式如下(I)所示:Cyantraniliprole is a new type of insecticide developed by Zhejiang Research Institute of Chemical Industry, code ZJ4042, chemical name: 3-chloro-N 1 -(2-methyl-4-heptafluoroisopropylphenyl)- N 2 -(1-methyl-1-cyanoethyl)phthalamide, the structural formula is as shown in (I):
该杀虫剂属新型邻苯二甲酰胺类杀虫剂,通过激活兰尼碱受体细胞内钙释放通道,导致贮存钙离子的失控性释放,是目前为数不多的作用于昆虫细胞兰尼碱(Ryanodine)受体的化合物。对鳞翅目害虫有广谱防效。The insecticide is a new type of phthalamide insecticide. It activates the intracellular calcium release channel of the ryanodine receptor, leading to the uncontrolled release of stored calcium ions. Alkaline (Ryanodine) receptor compounds. It has broad-spectrum control effect on Lepidoptera pests.
氯氟氰虫酰胺单独使用时用药成本较高,在一定程度上限制了其推广应用。氟铃脲用量较大,长期单独使用容易造成害虫抗性程度不断增加。因此,将氯氟氰虫酰胺和氟铃脲进行混配,是一种防治农业抗性害虫的有效方法。The cost of cyantraniliprole alone is relatively high, which limits its popularization and application to a certain extent. The dosage of hexaflumuron is large, and long-term single use will easily lead to the continuous increase of pest resistance. Therefore, mixing cyantraniliprole and hexaflumuron is an effective method to control agricultural resistant pests.

防治对象为柑橘潜叶蛾,在盛发期施药一次,喷液量1500kg/hm2。试验调查依据农业部药检所“农药田间药效试验准则(二)——杀虫剂防治柑桔潜叶蛾”规定进行。The control object is citrus leaf miner, and the pesticide is applied once in the blooming period, and the spray volume is 1500kg/hm 2 . The test investigation was carried out in accordance with the provisions of "Pesticide Field Efficacy Test Guidelines (2) - Insecticides Control Citrus Leaf Miner" by the Institute for Drug Control of the Ministry of Agriculture.
试验结果:见表4,供试药剂药后3d的防效为79.3%~81.2%,药后7d防效为92.3%~95.5%,药后14d防效仍达84.4%~86.7%,防治效果均好于对照药剂5%氟铃脲乳油和20%ZJ4042悬浮剂防效,持效期长。Test results: See Table 4, the control effect of the test agent after 3 days of application is 79.3% to 81.2%, the control effect of 7 days after application is 92.3% to 95.5%, and the control effect of 14 days after application still reaches 84.4% to 86.7%. Both are better than the control effects of 5% hexaflumuron emulsifiable concentrate and 20% ZJ4042 suspending agent of the control agents, and the duration of effect is long.

防治对象为棉铃虫,施药时为卵孵化高峰期,虫态以低龄幼虫为主。施药一次,施药量为750kg/hm2。试验调查依据农药田间药效试验准则(一)——杀虫剂防治棉铃虫”规定进行,每小区中间行数随机取5点,每点调查5株,共调查25株,药前调查虫口基数。The control object is cotton bollworm, when the pesticide is applied, it is the peak period of egg hatching, and the insect state is mainly young larvae. Spray once, and the spray rate is 750kg/hm 2 . The experimental survey was carried out according to the regulations of pesticide field efficacy test guidelines (1) - control of cotton bollworm with insecticides, 5 points were randomly selected in the middle row of each plot, 5 plants were investigated at each point, and a total of 25 plants were investigated. .
试验结果表明,供试药剂药后3d的防效为70.6%~76.2%,药后7d防效为93.2%~97.4%,药后14d防效仍达87.6%~90.4%,防治效果均好于对照药剂5%氟铃脲乳油和20%ZJ4042悬浮剂防效,持效期长。The test results show that the control effect of the test agent is 70.6% to 76.2% after 3 days of application, 93.2% to 97.4% after 7 days of application, and 87.6% to 90.4% after 14 days of application. The control effects of 5% hexaflumuron EC and 20% ZJ4042 suspending agent of the control agent were long-lasting.
