Under the guidance of Chairman Mao’s revolutionary line, at the climax of Dazhai in agriculture, in order to find out the methods, means and experiences of the large-scale aircraft to prevent and control the more and more efficient pest of pine needles, under the leadership of Party committees at all levels, this year, in Bishan County For the first time launched a plane control pine needles pest test. Test area of 10,000 mu, is divided into six operating areas, with five kinds of pesticides 3323.5 kg, 57 aircraft sorties, flight time 20 hours and 29 minutes, work safety, the effect is good. After investigation, the insecticidal effect in the chemical control area is generally about 90%, the effect of the main shoot tip is up to 98.9%, generally about 80%, and at the same time, controlling the pine caterpillar disaster in the area of the fly control area. The test result proves that the plane control Pine shoot pests with high efficiency, kill
