When trichlorfon sprayed forest with 0.8 kg per hectare of air, the concentration of trichlorfon in the air was 707 mg / m ~ 3 for 1 to 14 days and the air residual concentration was 4.5 ~ 0.4 mg / m ~ 3. Artificially sprayed trichlorfon to grapes at a concentration of 0.0003 and 0.001 mg / m3 in the air at levels of 2 and 6 kg per hectare. In the preparation and storage of trichlorfon solution working environment air, the concentration of 3 mg / m ~ 3. Spray the enemy with an airplane
