烟熏剂(简称烟剂)是由农药原药、发热剂、助燃剂、发烟剂、分散剂等采用特殊方法配制而成。施放烟剂防治大棚、温室内蔬菜病虫害是一种新的施药方法。烟剂经点燃后即发烟,农药有效成分因受热而气化,在空气中又凝聚成固体微粒充满烟雾所能达到的空间,最后农药有效成分均匀分布植株表面而起杀虫治病作用。由于烟雾具有“无孔不入”的特点,因此烟剂广泛用于大棚温室。一、烟剂的特点高湿、病虫害重是棚室蔬菜的特点。传统的喷雾防治方法用工多,劳动强度大还会增加大棚湿度,降低棚温,致使防治效果差。在阴雨天气又不宜采用喷雾防治,从而延误最佳防治时机。而采用烟剂进行熏烟防治,则不需器械,使用方便,省工省时,操作者点燃烟剂即离开,烟剂充满值 Fumigant (referred to as the smoke agent) by the original pesticide, fever, combustion improver, smoke agent, dispersant, etc. prepared by a special method. Casting tobacco control greenhouse, greenhouse vegetable pests and diseases is a new method of application. Tobacco smoke after ignition, the active ingredients of pesticides because of heat and gasification, in the air and condensed into solid particles filled with smoke space can be reached, and finally the active ingredients of pesticides evenly distributed plant surface and play a role in insecticide treatment. As the smoke has “all-pervading ” features, so widely used in greenhouses greenhouse smoke. First, the characteristics of tobacco smoke, pests and diseases are the characteristics of greenhouse vegetables. Traditional spray prevention and control methods work more labor intensive will increase the greenhouse humidity and reduce shed temperature, resulting in poor control. Spray in the rainy weather should not be used to prevent and control, which delays the best time to prevent and cure. The use of smoke for fumigation control, you do not need equipment, easy to use, save time and labor, the operator ignites the smoke that is leaving, the smoke is full of value
