Abstract:

To understand current situation of control technologies of fungicide application in apple production, 32 apple orchards in main apple producing areas in Henan Province were investigated through visits and face-to-face interview, to analyze the fungicide application in the whole growth period of apple. The following problems are found by the study: the operation process in apple production is not standardized; a great varieties of fungicides are used in different apple orchards, and the application of chemical fungicides are more than that of biological agents; and there are significant differences in the application amount of fungicides in different orchards. Among the 32 orchards, the least application amount of fungicide is 27 kg/hm2, and the most is 280.5 kg/hm2. The application frequency is also different among the 32 orchards, the least is 6 times, and the most is 14 times. The corresponding methods are put forward to establish a process control technology system of fungicide application in apple production.
