For greenhouse cultivation, at the early stage, fumigation by igniting smoke can be used for control. Each time, use 7500-12000 g of commercial 10% chlorothalonil smoke agent per hectare of greenhouse, or 3750-6000 g of commercial 20% chlorothalonil smoke agent, or 2500-4000 g of commercial 30% chlorothalonil smoke agent, or 1667-2667 g of commercial 45% chlorothalonil smoke agent, ignite and fumigate. It can also be controlled by dusting with 15000-22500 g of commercial 5% chlorothalonil dust per hectare; further control depends on the development of the disease.
