在植保工作上利用有益生物防治农作物病虫的群众性科学实验活动,正在蓬勃发展。近几年来,我省通过较大规模生物防治的实践,使人们更加认识到,生物防治具有花钱少,收效大,便于大搞群众运动;对害虫有较持久的控制作用;保护天敌资源,不杀伤自然界有益生物;无残毒,无抗性,不污染环境,对人畜和作物安全;减少治虫用工、用械,节省化学农药,降低生产成本等优越性,符合“备战、备荒、为人民”和
Mass scientific experiments on the use of beneficial organisms in the prevention and control of crop pests and diseases in plant protection work are booming. In recent years, our province through the practice of larger-scale biological control, make people more aware that biological control with less money, large effect, easy to engage in mass movement; have a more lasting control of pests; protection of natural enemy resources, No killing of natural beneficial organisms; no residue, no resistance, no pollution, no pollution of the environment, the safety of people and livestock and crops; reduce pest management, equipment, chemical pesticides to save and reduce production costs and other advantages, in line with “preparing for the shortage, for the people” with
