Problems solved by technology

The pest is highly concealed, and the young larvae are difficult to be found under the cover of wheat straw; in addition, the pest damages faster, and the older larvae eat more, start to overeat, and can group together to cause damage in a short period of time. The phenomenon of dead seedlings, and general spraying or poisonous soil, etc. are difficult to penetrate the thick wheat straw to contact and kill insects

Abstract

The invention relates to a preventing and controlling method for agricultural pests, and in particular relates to an efficient emergent preventing and controlling method for athetis lepigone. The athetis lepigone is prevented and controlled in a mode of combining chemical prevention and control of phoxim and indoxacarb and treatment of field wheat straws, or the athetis lepigone is prevented and controlled in a mode of combining chemical prevention and control of phoxim, fulvic acid and indoxacarb and treatment of field wheat straws; the method has the advantages of quick response and high efficiency in prevention and control, the prevention and control effect in 24 hours can reach over 90 percent, and the prevention efficiency is still over 90 percent after 7 days; the consumption of pesticides in the method is reduced, the cost is reduced, and the method is simple and easy to operate; and the manpower physical prevention and control measure is also combined in the method, so that the prevention and control effect is improved, and the prevention and control aims of high efficiency and quick response are fulfilled.

Description

technical field [0001] The invention relates to a method for preventing and controlling agricultural pests, in particular to an efficient and emergency method for preventing and controlling the spodopteryx moth. Background technique [0002] Two o'clock moth[ Athetis lepigone (M?schler, 1860)] is a new agricultural pest in my country's summer corn production areas. [0003] According to relevant records, in July 2005, it was first discovered in Shijiazhuang, Hebei Province in China that the two-spot moth damages summer corn seedlings, bores the base of the stem, causes the seedlings to wilt and die, or bites off the corn roots, leading to lodging, causing Serious lack of seedlings and monopoly, this is the first report in China. According to reports, in 2010, Noctuid moths commonly occurred in the central and southern summer corn areas of Hebei Province. In 2011, they broke out in Hebei, Henan, Shandong, Shanxi, Anhui, Jiangsu and other provinces, with an area of ​​more th...
