It works well for controlling and inhibiting harmful bacteria.


Putting the onion seeds into 500 times potassium permanganate solution(105 cell plant trays bulk), because the different varieties of the same crop have different resistance to heavy mites, replacing the varieties is one of the most economical and effective methods for disease prevention. It is possible to test and introduce other varieties to give full play to the unique resistance of certain varieties. Soaking with 40% formalin 300 times solution for 3 hour(50 cell plant trays bulk)s, then washing with water to dry and sowing, can control green onion purple spot disease, anthracnose disease.


(large round plastic flower pots in bulk)Rinse with clean water and sown after drying. The above are the causes and preventive measures of the disease of the onion(128 cell plant trays bulk).
