Do a good job of wheat straw treatment can control the two-point nocturnal moth

Most of the year's grain production is in autumn grain, and the two-point nocturnal moth is a pest that seriously threatens corn production. In order to comprehensively do a good job in the prevention and control of the two-point committee night moth and ensure a bumper harvest of autumn grain, the Hebei Provincial Plant Protection and Plant Inspection Station recently held a training course on the monitoring technology of the two-point committee night moth in Pingxiang County, Xingtai City.

The two-point nocturnal moth is a typical pest caused by the popularization and promotion of straw return, no-tillage sowing and other protective tillage conditions in the Huang-Huai-Hai wheat-maize continuous cropping area, because the adult insects have the characteristics of agglomeration and concentrated harm, once the field is found as a pest, the amount of insects is very large, a corn seedling around as few as 3-5 larvae, more than 20 heads, drilling the base of the moth corn stem under the wheat straw cover, strong concealment, difficult to find, difficult to control, in the field wheat straw covered with wheat stubble area can cause 80%-90% of the dead seedling rate.

At the training class, Dong Zhiping, an expert on the prevention and control of the night moth of the Two-Point Committee and a researcher at the Millet Institute of the Hebei Academy of Agriculture and Forestry Sciences, explained in detail the occurrence law, outbreak mechanism, characteristics of the night moth of the Two-Point Committee, and the key points of prevention and control. The "long wheat straw covered with more stubble" caused by wheat mechanization harvesting is an essential core condition for attracting adult insects to come in and lay eggs. During the wheat harvesting and corn sowing, all measures are taken to destroy this condition, so that the corn seedlings are not covered with wheat straw and wheat bran, and the harm of the two-point night moth can be avoided without pesticides.

At present, all parts of Hebei Province have fully implemented the green prevention and control technology of the two-point committee night moth, and adopted ecological control measures such as fine crushing of straw, stubble eradication, and ridge clearance when wheat is harvested, and the harm can be completely controlled through ecological technology to ensure that the corn seedlings are fully grown. At present, this technology has been included in the main agricultural technology of Hebei Province and the Ministry of Agriculture and Rural Affairs.

The training meeting showed the green prevention and control technology modes such as fine crushing of straw, removal of field wheat straw, rotary tillage stubble, eradication of wheat stubble, removal of sown wheat straw, specialized attractants, and high-efficiency insecticidal lamps, as well as related agricultural machinery such as new wheat harvesters and corn seeders, and conducted on-site observation of the field operation effects of various technologies, shared the large-scale demonstration effects of various places, strengthened the in-depth understanding of the ecological regulation technology of the two-point committee night moth, and clarified the significance and importance of the promotion of the technology.

Zhang Qiusheng, director of the Hebei Provincial Plant Protection and Plant Inspection Station, said that ecological regulation and control during the wheat harvest and corn sowing period is a very good green prevention and control technology, the technology is clear and reliable, and all localities should use broadcast loudspeakers, hanging banners, mobile phone WeChat and other ways to publicize, promote and implement well, and solve the "last kilometer" of technology landing.

Shijiazhuang, Xingtai, Handan and other 8 districted cities and Xinji, Dingzhou City plant protection station and 28 counties and districts plant protection station chiefs and technical personnel and other more than 80 people participated in the training, the participants said that in the future, we should actively publicize and popularize the green prevention and control technology of the two-point committee night moth, solidly carry out monitoring and prevention and control work, and strive to achieve "insects to seize grain" and ensure a bumper harvest of autumn grain.
