Etc.) Control of grass damage, timely shoveling, and promote the robust growth of crops such as corn, cotton, soybeans, sweet potatoes, peanuts, potatoes, beets, and miscellaneous grains, and increase the effective tillering of rice.

At present, cotton in all cotton areas in the country has entered the stage of vigorous growth of buds, cotton plants and leaves are dense, and in the period of rainy, high humidity and high temperature, therefore, it is necessary to timely pruning and topping to improve the ventilation and light transmission conditions of cotton fields to reduce flower buds. Fall off. The high temperature and high humidity of the southern rice area, combined with some rainstorms in the early stage of the rice area, some leaves are torn, and even the rice straw is broken, which is prone to rice planthopper, rice leafhopper, bacterial blight, sheath blight, rice blast, etc. Diseases and pests should be monitored and timely prevented.
  Midsummer is a frequent season of strong convective weather such as short-term heavy rainfall, thunderstorms and hail in China. Preventive work should be done. Field work should avoid strong convective weather such as thunderstorms or hail, so as to avoid casualties.
