What to Do About Continuous Garlic Cropping? Detailed Explanation of Prevention and Control Methods
Question: Because garlic has been planted for many years, the garlic in the field now gets sick every year, and the bulbs get smaller year after year. Changing the seed garlic does not help. Is it a problem with the soil? What should be done? Answer: When garlic is continuously cropped for many years, various soil-borne diseases and root maggots worsen year by year, which can easily lead to garlic disease and poor growth. For the above fields, it is best to practice paddy-upland rotation of garlic with rice, or rotate garlic with non-garlic upland crops for more than 3 years.
