Shed aerosol pesticide spraying technology
The application of aerosol pesticides to control greenhouse vegetable pests and diseases is not only easy to operate, but also greatly reduces the labor intensity, and the control effect is obviously superior to the spraying method, especially the humidity in the greenhouse is not increased, and the prevention and treatment of diseases is more thorough. The main points of its application techniques are as follows:
Application time According to the characteristics of greenhouse vegetable production, it is best to apply the aerosol after sunset in the evening to allow it to smoke at night, because during this period it is more conducive to the sinking of the mist of the smoke agent, and the control effect is more ideal.
Casting method Fixed-point smoke collection: Select several smoke-extracting points, place the smoke agent evenly on the ground, and ignite with incense or cigarette butts. A lot of smoke agents are packed in 100g small bags. The greenhouse can be used in whole bags. The small shed can put the smoke powder in a small paper tube rolled up by old newspapers, insert it into the fire, ignite it, or put 100 grams of smoke column. Used in two segments. The ignition sequence is sequentially ignited from the shed to the shed.
Mobile smoke: Place the smoke agent on the shovel. After ignition, hold the shovel and slowly move from the shed to the outside of the shed. However, using this method to prevent poisoning is generally not recommended.
The dosage should be applied in accordance with the principle of cost-effectiveness, and the appropriate dosage should be selected according to the target. Such as prevention and treatment of cucumber downy mildew, epidemic disease, tomato early blight, late blight, gray mold, etc., 10% procymidone can be used, 250-300 grams per acre, and the dose of greenhouse disease is increased to 400. ~500 grams; such as powdery mildew optional 15% carbendazim smoke agent, 250-300 grams per acre, or 250 grams of sulfur powder per acre, 500 grams of sawdust for fumigation; control of sclerotinia, optional 10 % Suikeling smoke agent, 250-300 grams per acre; prevention and control of aphids, powdery mildew and other pests, optional 10% isopropanol aerosol, shed insects to kill aerosols, etc., the amount of 250-300 grams per mu The indoor smoke and smoke agent should be sealed for at least 4 hours, and the time for smoking should be carried out before and after sunset. The next day, the vents can be fully opened for ventilation.
The use of chlorothalonil aerosols can only be carried out in greenhouses or greenhouses, and must be closed tightly.
