Stickworm control agent inventory

The armyworm is a lepidopteran, a noctuid pest, mainly a cereal crop. In the north of China, 33 degrees north latitude, no insects can overwinter and can move far away. According to the law of migration, China can be divided into four main areas. In winter, the wintering generation areas (Guangdong, Guangxi, Yunnan, Yunnan, and Guinan) are harmful to wheat and green manure crops; the adults of emergence have moved to the first generation area (Shanghai, Jiangsu, Zhejiang, Anhui, Henan, and Lunan), 3 ~ April larvae harm wheat and barley; feathered adults migrated to the second generation area (Northeast, North China, Inner Mongolia, Shandong Peninsula, Shaanxi, Gansu, Ning, Yun, Gui, Sichuan), and the larvae from June to July Cereal crops; the emergent adults migrated to the third-generation area (Northeast, North China, Shandong, etc.), and the larvae in August affected millet, corn and sorghum; the feathered adults moved back to the wintering area. The insects are heterozygous and can feed on more than 100 species of plants and eat grasses. The second-generation armyworm is an important pest in the corn seedling stage of Henan Province. It is gluttonous, sudden and migratory. It often bursts into a disaster in some areas. In severe cases, the leaves are eaten to form a polished rod, resulting in lack of seedlings and ridges. Even overwhelming.

Agents capable of controlling corn worms include carbofuran, chlorantraniliprole, chlorpyrifos, deltamethrin, emamectin, lambda-cyhalothrin, guanidine, methomyl, parathion , phoxim, spinosad, thiodicarb, etc., but some of these agents, such as carbofuran, chlorpyrifos, parathion, are more toxic, especially chlorpyrifos since December 31, 2016, banned Used on vegetables; Carbofurt will be banned from use in 2020; parathion has been banned from production, sale and use by the state. The currently registered drugs for controlling corn worms in China are: 200 g / liter of chlorantraniliprole suspension; 2.5% cyhalothrin emulsion (halofurabin can kill those of conventional pesticides such as Organophosphorus-resistant pests, the market has developed rapidly, registered in many countries); 30% acephate emulsifiable concentrate; 50% chlorantraniliprole seed treatment suspension, these agents are moderately toxic And below, this reflects from one side, in order to ensure the quality and safety of agricultural products, ecological environment safety and people's life safety, the pesticide industry actively develops high-efficiency, low-toxic alternative products and accelerates the delisting of highly toxic pesticides.
