Spodoptera frugiperda, commonly known as fall armyworm, belongs to the genus Trichoplusia in the family Lepidoptera, Spodoptera frugiperda, is a omnivorous pest native to tropical and subtropical regions in America, is widely distributed in the continental America, is harmful to various crops, and is evaluated as ten plant pests in the world by CABI (CABI) in the International agricultural and biological sciences center in '2017 report on the status of plants in the world'. Spodoptera frugiperda has now become a major pest that damages crops in our country.
Carbosulfan belongs to carbamates, and the toxicity mechanism of the carbosulfan is to inhibit the activities of acetylcholinesterase (Ache) and carboxylesterase of insects, so that acetylcholine and carboxylic ester are accumulated, and normal nerve conduction of the insects is influenced to kill the insects. Carbosulfan is one of low-toxicity carbosulfan varieties, has moderate oral toxicity, low percutaneous toxicity, no accumulated toxicity, no deformity, carcinogenesis and mutagenesis. The toxicity to natural enemies and beneficial organisms is low, namely the low-toxicity derivative of the carbofuran pesticide belongs to an efficient, safe and convenient-to-use insecticide and acaricide, and is one of ideal substitute varieties of the highly toxic pesticide carbofuran. It features high liposolubility, systemic nature, penetrability, quickly taking its effect, low residual, long residual effect, high safety, and no damage to crops.
Dinotefuran is the latest generation of super nicotine pesticide. The chemical structure of the pesticide is different from that of the existing nicotine pesticide, the tetrahydrofuran group of the pesticide replaces the prior chloropyridyl and chlorothiazyl, and does not contain halogen elements. Meanwhile, the pesticide is different from nicotine in performance and has a wider insecticidal spectrum, so that the pesticide is called as furanonicotine. Dinotefuran has the characteristics of contact poisoning, stomach toxicity, strong root systemic property, high quick effect, long lasting period, wide insecticidal spectrum and the like, has excellent control effect on pests with sucking mouth parts, and shows high insecticidal activity at a very low dosage. The insecticidal composition is mainly used for preventing and treating aphids, leafhoppers, plant hoppers, thrips, whiteflies and resistant strains thereof on various crops such as wheat, corn, cotton, vegetables, fruit trees, tobacco leaves and the like, and has high efficiency on coleoptera, diptera, lepidoptera and homoptera pests.
As for the patents for controlling Spodoptera frugiperda, a patent of an insecticidal composition containing emamectin benzoate and dinotefuran and application thereof (application No. 202010050420.6) and a patent of a pesticide composition and application thereof in controlling Spodoptera frugiperda (application No. 202010280681.7) and the like are reported, but the patents are all dosage forms for spraying. Only patent 'a pesticide granule for controlling spodoptera frugiperda' is reported at present in the aspect of controlling spodoptera frugiperda in granules (application No. 201910644051.0), but the following patents: 1. the patent contains plant growth regulator, and the dosage of the plant growth regulator is known to be difficult to control, less, no effect and more, which is easy to generate phytotoxicity, so the method is not suitable for large-area popularization. 2. The main pesticide component 'cyantraniliprole' in the patent is a patent component of foreign enterprises and can not be produced in a commercialized way in China at present within the validity period.
The invention relates to a slow controlled release pesticide fertilizer prepared by compounding carbosulfan and dinotefuran for the first time on the basis of screening biological activity of a large amount of compounds and improving a production process in recent two years, and the slow controlled release pesticide fertilizer is applied to the root of Spodoptera frugiperda for preventing and treating Spodoptera frugiperda.
