Crop Diseases and Pests Seriously Threaten Autumn Grain Production
At present, the northeast spring maize is in the tasseling to filling stage. The maize in North China is in the stage of heading and flowering. The middle-late rice in the south is in the period from tillering to heading. It is the critical period for the formation of yield, and it is also an important period for pest prevention and control.
Since the beginning of summer, the weather has been extremely anomalous, and diseases and insect pests have tended to occur. In particular, armyworm has been exposed in Hebei, Inner Mongolia, Jilin, Heilongjiang, Liaoning and Tianjin. Mythimna separata is a migratory and fulminant omnivorous pest. The three-generation larvae of Mythimna separata, which have been successively outbreaks in various regions, are rare in the past 10 years because of their large area, wide range, and high density. This poses a serious threat to the safety of production of autumn crops such as corn, millet, and rice. The plant protection station of Heilongjiang Province detected that three generations of the armyworm are expected to show an outbreak in the province. In view of the fact that crop plants such as corn are relatively high and their agricultural activities are relatively low, the third-generation armyworm has the characteristics of concentration, concealment, and outbreak. Heilongjiang Provincial Plant Protection Station requires the plant protection departments of various places to immediately take action and quickly turn on the report lights or set up poplar branches. The trapping worms were monitored to accurately predict the number of adult insects and investigate the oviposition situation. The occurrence and occurrence of the third generation armyworm larvae were predicted in time, and the forecast information was issued in advance. In order to effectively control the pests of the armyworm, the Ministry of Agriculture specially formulated the technical guidance for the prevention and control of armyworm in 2012 (see the 3rd edition for specific technologies). At the same time, the occurrence of rice planthoppers and rice blast disease in southern rice and rice fields in northeastern China is also heavier than usual.
In accordance with the deployment of the Ministry of Agriculture, the climax of the harvest of the autumn crops was quickly set off in various parts of the country. The Ministry of Agriculture requires all localities to implement the responsibility system for prevention and control of pests and diseases, increase the frequency of monitoring investigations, closely monitor the development of insect pests, timely release information on pests and diseases, carry out timely pest prevention and control, and ensure early warning, early preparation, and early prevention. control. It focused on the monitoring of armyworms in the northeast and north China, rice planthoppers in the Yangtze River valley, rice leaf roller, rice blast, and potato late blight in northwestern China.
