If you want to control diseases and insect pests more effectively, you can refer to the following methods: the best control period for bushy dwarf disease is in the middle of March. Spray the adjacent insect source wheat field with 1000 times of methamidophos or 1500 times of omethoate. When the rust leaf rate reached 10% from early March to mid-April, the mu was sprayed with 20% trimethoprim EC 30ml plus 75kg water, and sprayed again at intervals of a week. When the diseased leaf rate of powdery mildew reaches 30% from early April to early May, or when the flag leaf occurs sporadically, the mu is sprayed with 50 ml of 20% strychnine EC and 75 kg of water. 50% carbendazim 500 times solution was used to control scab when diseased plants were found in wheat fields from late April to mid-May. When there are more than 10,000 insects per mu from late April to early May, the armyworm is sprayed with 1500 times of monocrotophos. When trematodes have more than 5 larvae per 15 cm × 15 cm × 20 cm soil samples in mid-late April, use 50% 1605 EC or 50% phoxim EC 200 ml mixed with 3 kg of water and 30 kg of fine soil per mu. From late March to late May, when the aphid plant rate reached about 50% and the number of 100 aphids reached more than 500, the wheat aphid was sprayed with 40% omethoate 1500 Mel 2000 times solution.
