At present, millet in spring season in northern China has entered the jointing stage, and millet in summer valley has also begun to seal ridges. Due to the recent heavy rain in northern China, the humidity in the field is relatively large, and it is easy to cause epidemic diseases such as gluten, rust, and brown strips. The occurrence of diseases such as disease and sheath blight, and the occurrence of high-temperature diseases, provide good conditions for the reproduction of pests such as Miscanthus, Mythimna separata, millet ash, and corn borer. It is likely to cause large-scale damage during the late growth period of millet, especially in 2012. The heavier armyworms and Millet flies that occur in China need to be strictly prevented. Here are the main diseases and pests that should be noticed in the middle and later stages of millet and its prevention and control methods: The disease is currently the main epidemic disease that harms the millet in China. It occurs every year, especially in Hebei, Henan and Xiagu districts in Shandong. The disease usually occurs after jointing. If it continues to be cloudy during the early period, it is likely to cause extensive damage. Can be used 75% of tricyclazole WP 1000 times, 2% of kasugamycin wettable powder 500 to 600 times the liquid in the initial stage of spraying for the lower leaves, 7 days after the spray. Last year, serious land masses could be sprayed ahead of jointing and prevented. After severe headings occurred in the lobe, they should concentrate on the panicle after heading to prevent the occurrence of the panicle blast. Brown bark disease last year, due to cloudy days during the jointing period of rain, the incidence of brown bark in the millet-producing areas increased significantly. Remind farmers friends that after jointing, if continuous wet and rainy, you can use 72% of agricultural streptomycin sulfate 4000 times or 20% Thiosen copper suspension 500 times, focus on spraying in the heart and leaf areas to prevent brown strip disease in advance occur. At the same time, it is possible to add a low amount of imidacloprid in a suitable range to treat pests that harm the heart and leaves, and the effect is better. Rhizoctonia cerealis is a common disease in millet production areas. Sites with high density of seedlings are prone to occur, and 12.5% ​​of diniconazole WP can be used during jointing, and 400 to 500 times of the liquid can be used, or 15% of Triadin WP can be used as a 600-fold spray to control the base of the millet stem once. , 30 kg per mu of liquid medicine, 7 to 10 days after the discretion of the defense once. Based on the occurrence of the second-generation armyworm in spring gorge region in northern northern China, it is suggested that preparations for the prevention and control of three generations of armyworm should be done in the middle and late August of the summer valley. In the first half of August, field pest surveys should be conducted to guide the farmers. Timely medication before 3rd age. The fumigation method can be used to prevent and cure: 80% dichlorvos EC per acre 200 to 250 ml water 2 liters mixed 5 kg of sawdust, in the evening sprinkled in the millet rows, every 4 to 5 ridges to spread a row, use the fumigation of dichlorvos to kill the armyworm Or with 90% trichlorfon crystals, 80% dichlorvos EC 800 to 1000 times or 4.5% beta cypermethrin EC, 20% fenvalerate EC 2000 ~ 2500 times spray. The Miscanthus fly is severe in the northeastern Jilin and Chengde spring valleys and is also endangered in the Xiagu district as well as in the hilly and hilly areas. At present, the spring valley area is at a critical stage in the occurrence of the second-generation Millet flies, and it is also the best period for prevention and control. Available 4.5% beta cypermethrin EC, 2.5% deltamethrin EC or 20% Fenvalerate EC 1500-2000 times, focusing on spray control of stalks and heart parts.
