Chitin fungicides are a new type of fungicide that has recently emerged. They not only have fungicidal and disease-prevention effects, but can also promote the growth and development of fruit trees, increase fruit tree yield and quality, and are relatively good for improving the environment. They are worth promoting in current pollution-free cultivation of fruit trees. Three chitin fungicides are introduced here.
1. Yishizhuang: Also known as Green Plant Protection Agent No. 2, it can induce plant gene regulation, activate plants, enhance the immune function of fruit trees, improve disease resistance, and form a film on the plant surface that acts as protection, preventing pathogen infection and preventing the occurrence of fruit tree diseases. This agent also has the characteristics of promoting the absorption of nutrients by fruit trees, resisting adverse environments, and accelerating the growth and development of fruit trees. It has a notable effect on promoting reproductive growth and improving fruit quality of fruit trees. This agent is suitable for various fruit trees. From before flowering to the fruit formation stage, dilute the 2% Yishizhuang aqueous solution with water to a 600-800 times solution and spray once every 5-7 days, for 2-3 consecutive sprays.
2. Judang Guole: It has effects such as inducing resistance, preventing disease occurrence and resisting pathogen invasion, promoting growth, and improving quality. It is mainly suitable for various berry-type fruit trees, with a large yield increase range and significant quality improvement. It can increase the fruit-setting rate by 3-4.5%, and promote uniform fruit shape, smooth fruit surface, bright color, and consistent ripening. It is suitable for fruits such as strawberries and grapes. When applied during the fruit-setting stage, it protects fruit trees from pathogen infection, reduces disease occurrence, and improves resistance to adverse environmental conditions. Starting at the fruit appearance stage (not too late), spray the 1.5% Judang Guole aqueous solution at a 600 times dilution for 2-4 consecutive sprays, once every 6-7 days. Like Yishizhuang, this agent cannot be mixed with alkaline pesticides and should be stored in a cool, dry place.
3. Heixing 21: Also known as Heixingling, it has effects such as inducing resistance, inhibiting pathogen infection, increasing biological yield, and improving quality. It is mainly used to control fruit tree scab, especially with good results in controlling pear scab. Before disease onset or in the early stage of disease, use the 2% Heixing 21 aqueous solution at a 400-600 times dilution, spraying once every 7 days for 2-3 consecutive sprays. If rain washes it off within 4-6 hours after spraying, spray once again as a supplement. This agent should be stored in a cool, dry place.
