In May , the winter wheat gradually plucked from south to north, which is the key period for determining the multi-grain weight of wheat grains. The occurrence of pests such as powdery mildew, rust, scab, sputum, aphids, and spider mites has also followed. This period in time when a reasonable anti-pest, anti-premature aging, to ensure that wheat production is very important. For different pests and diseases, it is the most scientific choice to treat and prevent diseases, rationally match drugs, use drugs to prevent and control, and comprehensive prevention and control.
In the early stage of early flowering, the prevention of scab and the treatment of the larvae in the early stage of flowering: in recent years, the damage of wheat scab in the winter wheat area in the north has increased year by year, especially in 2012 , the whole area of ​​winter wheat and the north China and the north of China have a large-scale epidemic of wheat scab, giving wheat The production caused a significant loss. In 2013 , the occurrence of wheat scab is still grim, and it must be highly valued and strictly controlled.
The peak period of wheat scab infection is in the early stage of wheat flowering under the condition of rain or dew. Therefore, it is very important to see the application of drugs in the day. At the beginning of May , when wheat enters the flowering stage, if it encounters continuous rain and high humidity, spray the medicine as soon as possible to prevent disease. You can choose more than 40% more than Fu bromide wettable powder 800 times solution, 10% flusilazole 1000 times solution or 25% myclobutanil 2000 times solution, etc., not less than 30 kg of liquid per acre and Silicone additive, evenly sprayed with wheat ears. It is necessary to use the amount of foot medicine, and it will be rained within 3-6 hours after application . It should be replenished in time after rain. In areas of high graminearum drug resistance has been generated carbendazim, carbendazim stop using benzimidazole-based agents, in order to ensure the control effect; diseases such as epidemic prevention first end, for an interval of 5-7 days Prevention and control for the second time to ensure control of epidemic hazards. The liquid can be mixed or coupled with cypermethrin cyhalothrin midge adults like to rid the like.
After April 20, a large area of snow to cool northern winter wheat region, there will be a greater impact on the booting is in the spikelets of wheat seed, so the best time of spraying and other cytokinins or potassium dihydrogen phosphate added to Promote Small The ears are strong.
In the early stage of post-grouting, the prevention of powdery mildew and rust in the early stage of grain filling: wheat bran has been the main pest concentrated in the panicle during the grain filling stage of wheat. If it is not properly controlled, it has a great influence on the grain weight of wheat. But how to do a one-time spraying control effect can be achieved, but also pay attention to. From the greening to the filling stage, wheat aphids gradually spread and spread in the field. The sultry weather in the early stage of grain filling is conducive to the reproduction and expansion of the ear mites, and special attention should be paid to its dynamics. When there are more than 5 aphids per ear, they should be sprayed immediately. The choice of 10% imidacloprid WP 20 g / mu, lambda-cyhalothrin 2.5% microemulsion of 40 mL / mu, in view of these agents no fumigation, spraying must be sprayed uniformly when not less than 30 kilograms per acre Liquid medicine. Wheat field with mild powdery mildew and rust can be treated with 25% nitrile emulsifier or propiconazole in the liquid . It is best to mix high-quality potassium dihydrogen phosphate and prevent dry heat. Grain weight.
Wheat heading to filling stage is a key period for the occurrence of damage caused by various diseases and insects such as scab, stripe rust, wheat stubble, and midges. The rational mixing of pathogenic fungicides, insecticides and plant growth regulators or foliar fertilizers is selected. Use, timely use of drugs, even spraying, disease prevention and control of pests against dry hot air, to achieve "one spray three defenses", save labor and improve the production and production. Remind, midge retransmission area, should take full advantage of the persistence of the agent, the appropriate forward prevention and treatment time, treatment occurs early in the adult.
