Answer: The young fruit before apple bagging is delicate and the lenticels have not been closed. If the concentration of compound pesticides is high, it is easy to produce phytotoxicity, resulting in large fruit spots and more fruit rust. No mother liquor was first formulated and the pesticide was difficult to form a stable and uniform solution. Spraying on the fruit will also cause fruit rust. During the growing season, nitrogen fertilizers such as urea and ammonium bicarbonate and chicken manure and pig manure without adequate decomposing are used, and ammonia gas is generated at high temperatures, and fruit rust is also generated when the fruit is stimulated. When bagging, it encounters dense fog or dew weather, or it will be bagged immediately after spraying, which will aggravate the formation of fruit rust. The dry weather is flooded with water, and the water soars. The cells absorb water and swell. The fruit develops inside and outside. There is a crack in the peel and fruit rust is also formed.
