Pepper has just been planted in the greenhouse for a week. I want to spray it with hymexazol and potassium dihydrogen phosphate. What else do you need?

Evil is a soil fungicide, so spraying is not recommended. The planting process of pepper is a process of raising roots. After planting, root irrigation should be carried out to prevent trees from dying. Use hymexazol and metalaxyl once, copper chloride once and twice in 20 days. As for the normal growth of potassium dihydrogen, it is unnecessary to use it. Why do seedlings weaken their own strength? They should stimulate their potential in various ways. Spraying isocyanuric acid on leaves can completely prevent and kill these three bacteria. My opinion is not consistent with that of all the candidates, so I dare not joke. Welcome to exchange different opinions.
