Description

含有氰氟虫腙的杀虫组合物 Metaflumizone containing pesticidal compositions

技术领域 FIELD

[0001] 本发明涉及的农药组合物,是以氰氟虫腙和阿维菌素或甲氨基阿维菌素苯甲酸盐为有效成分,用于防治农业上的害虫,尤其用于防治水稻稻纵卷叶螟、蔬菜小菜蛾等。 [0001] The present invention relates to pesticidal compositions, and is metaflumizone abamectin or emamectin benzoate as an active ingredient for controlling pests in agriculture, in particular for the control of rice rice leaf roller, diamondback moth and other vegetables.

背景技术 Background technique

[0002] 阿维菌素(abamectin),它是一种大环内酯双糖类化合物。 [0002] avermectin (abamectin), which is a macrolide compound disaccharides. 是从土壤微生物中分离的天然产物,对昆虫和螨类具有触杀和胃毒作用并有微弱的熏蒸作用,无内吸作用。 Microbial isolated from natural products, with contact and stomach action of insects and mites, and a weak fumigation, no systemic action. 但它对叶片有很强的渗透作用,可杀死表皮下的害虫,且残效期长。 But it has a strong penetration of the blade, the skin can kill pests and Vinca long. 其作用机制与一般杀虫剂不同的是它干扰神经生理活动,刺激释放r-氨基丁酸,而r-氨基丁酸对节肢动物的神经传导有抑制作用,若螨和昆虫与幼虫与药剂接触后即出现麻痹症状,不活动不取食,2-4天后死亡。 The mechanism of which is different from the general insecticides it interferes neurophysiological activity, stimulate the release r- aminobutyric acid, r- aminobutyric acid and inhibit the nerve conduction arthropods, insects and mites if contact with an agent larvae after having paralysis symptoms, no activities are not feeding, 2-4 days after the death. 但对捕食性和寄生性天敌虽有直接杀伤作用,但因植物表面残留少,因此对益虫的损伤小。 But predatory and parasitic natural enemies, although direct killing effect, but the little plant surface residue, therefore less damage to beneficial insects. · ·

[0003] 甲氨基阿维菌素苯甲酸盐(emamectin benzoate),高效、广谱、残效期长,为优良的杀虫杀螨剂,其作用机理阻碍害虫运动神经信息传递而使身体麻痹死亡。 [0003] Emamectin benzoate (emamectin benzoate), high efficiency, broad spectrum, Vinca long as excellent insecticidal acaricidal, its mechanism impede the transmission of information pests motor nerve paralysis Death Body . 作用方式以胃毒为主触杀作用,对作物无内吸性能,但能有效渗入施用作物表皮组织,因而具有较长残效期。 In the main mode of action of stomach contact action, systemic properties of non-crop, but the application of crop can effectively penetrate the epidermal tissue, and thus it has a long residual period. 对鳞翅目,螨类、鞘翅目及同翅目害虫有极高活性,且不与其它农作物产生交叉,在土壤和中易降解无残留,不污染环境,在常规剂量范围内对有益昆虫及天敌、人畜安全,可与大部分农药混用。 Lepidoptera, mites, Coleoptera and Homoptera has high activity, and do not intersect with other crops to produce, easily degradable in soil and residue-free, does not pollute the environment, within the usual dosage range of beneficial insects and natural enemies, human and animal safety, can be mixed with most pesticides.

[0004] 由于阿维菌素和甲氨基阿维菌素苯甲酸盐已在我国广泛使用多年,长年连续单独使用已经使害虫抗药性不断增强,即使不断加大施药剂量,也难以有效杀灭害虫。 [0004] Since the avermectin and emamectin benzoate has been widely used for years in our country, it has for many years of continuous use alone growing resistance to pests, even increasing the dose administration, it is difficult to effectively kill pests.

[0005] 氰氟虫腙(metafIumizone)是一种全新作用机制的杀虫剂,通过附着在钠离子通道的受体上,阻碍钠离子通行,与菊酯类或其他种类的化合物无交互抗性。 [0005] metaflumizone (metafIumizone) is a new mechanism of action of pesticides, by adhering to the ion channel of the receptor, hinder the passage of sodium ions, and other kinds of pyrethroid compound or no cross-resistance . 该药主要是通过害虫取食进入其体内发生胃毒杀死害虫,触杀作用较小,无内吸作用。 The drug mainly by insects feeding into its dead body of gastric poison pests, small contact action, systemic action None. 该药对于各龄期的靶标害虫、幼虫都有较好的防治效果,昆虫取食后该药进入虫体,通过独特的作用机制阻断害虫神经元轴突膜上的钠离子通道,使钠离子不能通过轴突膜,进而抑制神经冲动使虫体过度的放松,麻痹,几个小时后,害虫即停止取食,I〜3d内死亡,可以有效地防治各种鳞翅目害虫及某些鞘翅目的幼虫、成虫,还可以用于防治蚂蚁、白蚁、蝇类、蝉螂等害虫。 For each drug target pests instar larvae have a good control effect, the drug into the feeding insect parasites, insects block axon membrane sodium channels through a unique mechanism of action, sodium ions can not pass through the axonal membrane, thereby inhibiting the nerve impulses that the worm excessive relaxation, paralysis, after a few hours, i.e. to stop pests feeding, the I~3d death, can effectively control a variety of Lepidoptera pests and certain Coleoptera larvae and adults, can also be used against ants, termites, flies, cockroaches and other pests. 对哺乳动物无神经毒性,对鸟类的急性毒性低,对蜜蜂低危险,由于在水中能迅速地水解和光解,对水生生物无实际危害。 No neurotoxicity mammal, low acute toxicity to birds, bees low-risk, since the hydrolysis can be quickly and photolysis in water, no practical harm to aquatic organisms.

[0006] 不同农药品种的混配,是防治农业抗性害虫的常见方法。 [0006] different varieties of mixed pesticides is a common method for controlling agricultural pests resistant. 通过农药配方筛选,筛选出合理的配方,可有效提高实际防治效果,减少用药量,降低成本,延缓害虫抗药性的产生,是害虫综合治理的重要手段。 By pesticide formulation screening, screening out a reasonable formula, can effectively improve the practical control effect, reduce the dosage to reduce costs and delay the pest resistance is an important means of integrated pest management. 本发明人对氰氟虫腙和阿维菌素或甲氨基阿维菌素苯甲酸盐的混配进行了深入研究,发现氰氟虫腙和阿维菌素或甲氨基阿维菌素苯甲酸盐进行混配,在一定的混配比例范围对害虫具有明显的增效作用,经进一步研究,完成了本发明。 The present invention is of metaflumizone and abamectin or emamectin benzoate mixed salt conducted intensive studies, and found that metaflumizone abamectin or emamectin benzene formate compounded, a significant synergistic effect against pests at a certain mixing ratio range, further research, completed the present invention.
