At the initial stage of the disease, spraying once every 7 days can control leaf blast. Spraying once at the breaking stage and full heading stage can control panicle blast. Each time, use 75% chlorothalonil wettable powder 1500g to 1900g per hectare, add 1050 liters of water, mix and spray evenly.

2. It can be used to control rice sheath blight.

Spray every 7 days from the initial stage of the disease or the young panicle formation stage to the booting stage, each time with 75% chlorothalonil wettable powder with a commercial volume of 1500g to 1900g and 1050 liters of water, stir and spray evenly, focusing on the rice stem.

3. It can be used to control wheat leaf rust and leaf spot.

The initial stage of the disease was sprayed once every 7 days, continuously for 2 to 3 times, each time with 75% chlorothalonil wettable powder with a commercial volume of 1500g to 1900g plus 1050 liters of water, stirred and sprayed evenly.

If it is planted in the greenhouse, it can be ignited and fumigated at the initial stage, each time 10% chlorothalonil fumigant is used in each hectare greenhouse with a commodity quantity of 7500 and 12000g or 20% chlorothalonil fumigant is 3750m6000g or 30% chlorothalonil fumigant is 2500m4000g or 45% chlorothalonil fumigant is ignited and fumigated. You can also use 5% chlorothalonil powder with a commercial volume of 15000 to 22500g for prevention and control, and further prevention and control depends on the development of the disease.

6. It can be used to control tomato early blight.

The initial stage of the disease was sprayed every 7 to 10 days, continuously for 3 to 4 times, each time with 75% chlorothalonil or dachlorothalonil wettable powder 2200 kg 4000g per hectare or 40% chlorothalonil suspension 2250g 2625g plus 1125L water, spray evenly and reduce the amount of spray per hour of seedlings.
