The fungicide chlorothalonil can be used on the following crops:
1. Control of rice blast. To control leaf blast, start spraying when disease centers appear in the field, then spray again after 7 days. To control panicle blast, spray once each at the booting stage and the full heading stage of rice. Each time, use 1500-1900 grams of the commercial product of 75% chlorothalonil wettable powder per hectare (1125-1425 grams of active ingredient), add 1050 liters of water, stir evenly and spray.
2. Control of rice sheath blight. Spray at the early stage of disease occurrence or from the young panicle formation stage to the booting stage, then spray again after 7 days. Each time, use 1500-1900 grams of the commercial product of 75% chlorothalonil wettable powder per hectare (1125-1425 grams of active ingredient), add 1050 liters of water, stir evenly and spray, focusing the spray on the stems of the rice.
3. Control of wheat leaf rust and leaf spot. Start spraying at the early stage of disease occurrence, spray once every 7 days, and spray continuously 2-3 times. Each time, use 1500-1900 grams of the commercial product of 75% chlorothalonil wettable powder per hectare (1125-1425 grams of active ingredient), add 1050 liters of water, stir evenly and spray.
4. Control of peanut rust, brown spot and black spot. Start spraying at the early stage of disease occurrence, spray once every 7-10 days, and spray continuously
2-3 times. Decide whether to apply the pesticide again according to the growth period of the peanuts and the development of the disease. Each time, use 1500-1800 grams of the commercial product of 75% chlorothalonil wettable powder per hectare (1125-1350 grams of active ingredient), or 1500-2250 grams of the commercial product of 40% Daconil suspension concentrate (600-900 grams of active ingredient), add 900 liters of water, stir evenly and spray.
5. Control of cucumber downy mildew. Start spraying before disease occurrence or at the early stage, spray once every 7 days, and spray continuously 3-4 times. Each time, use 2200-4000 grams of the commercial product of 75% chlorothalonil wettable powder per hectare (1650-3000 grams of active ingredient), or 2250-2625 grams of the commercial product of 40% Daconil suspension concentrate or 40% chlorothalonil suspension concentrate (900-1050 grams of active ingredient), add 1125 liters of water, stir evenly and spray; reduce the spray volume when the cucumber seedlings are small. For the control of cucumber downy mildew in greenhouses, chlorothalonil smoke agents can be used. Ignite and fumigate at the early stage of disease occurrence. Each time, use 7500-12000 grams of the commercial product of 10% chlorothalonil smoke agent per hectare of greenhouse, or 3750-6000 grams of the commercial product of 20% chlorothalonil smoke agent, or 2500-4000 grams of the commercial product of 30% chlorothalonil smoke agent, or 1667-2667 grams of the commercial product of 45% chlorothalonil smoke agent (750-1200 grams of active ingredient) and ignite for fumigation. Alternatively, 15000-22500 grams of the commercial product of 5% chlorothalonil dust (750-1125 grams of active ingredient) can be used for dusting control; further control is decided according to the development of the disease.
6. Control of tomato early blight. Start spraying at the early stage of disease occurrence, spray once every 7-10 days, and spray continuously 3-4 times. Each time, use 2200-4000 grams of the commercial product of 75% chlorothalonil or Daconil wettable powder per hectare (1650-3000 grams of active ingredient), or 2250-2625 grams of the commercial product of 40% chlorothalonil suspension concentrate (900-1050 grams of active ingredient), add 1125 liters of water, stir evenly and spray; reduce the spray volume when the seedlings are small.
