在我区,为害甘蔗的主要害虫有甘蔗螟虫、蔗龟、绵蚜虫、蓟马和红蜘蛛。主要病害有风梨病、黑穗病和赤腐病。甘蔗遭受这些病、虫为害后,生长不良,往往导致减产和糖份下降。我们必须遵照毛主席“同病虫害作斗争”的教导,积极防治病虫害,夺取甘蔗高产丰收。 In our area, the main pests for sugarcane are sugarcane borers, caterpillars, cotton aphids, thrips and spider mites. The main diseases are wind pear disease, smut and red rot disease. Sugarcane suffers from these diseases, and after the pest infestation, poor growth often results in a decrease in yield and sugar. We must abide by the guidance of Chairman Mao’s “fight against pests and diseases” and actively prevent and control pests and diseases so as to seize high yield and yield of sugar cane.
