化学防治是害虫综合治理的重要措施之一。烟雾载药技术是利用烟雾机产生的高速热气流,将适量的药液在瞬间雾化成细小微粒,飘移至害虫体表,是防治林木害虫的一项先进施药方式。具有灵活方便,不受雨水、地形影响,成本低、工效高的特点。池州地区自90年应用推广,在控制马尾松、国外松、黄山松、杨树、枫香、毛竹等主要林木虫害上,应用广泛,成效显著。 1 控制松毛虫发生松毛虫是池州地区历史性虫害,马尾松纯林150万亩,常灾区50万亩,偶灾区30万亩。常灾区2～4年发生一次,偶灾区5～7年大发生一次。80年代,主要采用飞机灭虫、担架喷雾机喷雾、白僵菌生物防治等措施,虽取得一定效果,但未能彻底改变常灾区三年大发生一次的规律。每年需防治面积20万亩以上,其中在猖獗危害的80年和81年,飞防15万亩,耗资
Chemical control is one of the important measures for pest comprehensive management. Smoke drug technology is the use of high-speed thermal smoke machine fog, the right amount of liquid in an instant atomized into fine particles, drifted to the pest surface, is an advanced pesticide application of pest control. Flexible and convenient, free from rain, terrain, low cost, high efficiency. Since 90 years of application and popularization, Chizhou has been widely used in the control of major tree pests such as Pinus massoniana, Pinus armandii, Pinus taiwanensis, poplar, Liquidambar formosana and Phyllostachys pubescens, with remarkable results. 1 Control Dendrolimus Dendrolimus is a historic insect pests in Chizhou, Massive Pinus massoniana forest 1500000 mus, often stricken area 500000 mus, disaster area 300000 mus. The disaster area occurs once every 2 to 4 years and the disaster area occurs once every 5 to 7 years. In the 1980s, the main use of aircraft pest control, stretcher sprayer spray, Beauveria bassiana biological control and other measures, although achieved some results, but failed to completely change the regular disaster area once every three years. Each year need to control the area of more than 200,000 mu, of which rampant in the 80 and 81 years, flying anti-15 million mu, cost
