In the later stage of wheat management, good disease prevention and harvest should be achieved.

Due to the postponement of rice and cotton in the previous crop last year, leading to the postponement of wheat sowing date, coupled with the encounter of Rain Water for a long time in the suitable sowing date, the current growth is obviously not as good as in previous years. Therefore, in the management of wheat in the later stage, it is necessary to control "disease prevention" and "harvest":

First, we should do a good job in "disease prevention" and prevent and control the reduction of production due to illness. At present, wheat has entered the jointing and booting stage, because it is sunny and rainy, the humidity and high temperature in the field is suitable, which is beneficial to the occurrence of wheat sheath blight and scab, so it must be controlled again 10 days after the first pesticide. Prevention and control measures should be carried out in addition to clearing ditch and drainage, reducing humidity and reducing stains, and chemical control should be carried out. Wheat sheath blight can be treated with 30% benzyl propiconazole 20-30ml per mu, manual sprayer with 30 kg water, and sprayer with 20 kg water. The key to the prevention and control of wheat scab is to prevent the flowering stage of poplar. Generally, the first spray is from 10% of wheat heading to the early flowering stage, with an interval of 5 min for 7 days, and the second time. Use 50% carbendazim wettable powder 100 g or 70% methyl topiramate wettable powder 50 ml 75 g plus 50 kg water or 50 g dilute azole or 25% tebuconazole 15-20 g plus 30 kg water foliar spray per mu. Spray should focus on the wheat spike uniform spray, if it rains after spraying, it needs to be sprayed after the rain.

The second is to make a good "harvest" and harvest at the right time. The best harvest time of wheat should be carried out when the wheat grains are all yellow and the shape and color of the grains are the same as those of the original varieties. if there is continuous overcast and rainy weather, we should take advantage of the sunny weather to harvest, so as to prevent the continuous overcast and rainy harvest from causing "sprouting on the ear". Resulting in a reduction in yield and harvest.
