本试验是根据无毒高脂膜可防治多种植物真菌性病害的报进而开展的。结果证明,高脂膜对冬植番茄晚疫病的防治效果,与当地常用农药波尔多液相当,增产30％以上,防治春植番茄晚疫病和叶霉病的效畢,则相当于当地常用农药百菌清,增产幅度约20％。这为无公害防病提供了一种方法,值得进一步试验示范和推广。试验材料和方法 (一)试验材料 1.选黄埔区笔岗乡(冬植番茄主产区)番茄专业户朱柱兴的冬植“广茄一号”番茄(1935年11月5日播种,12月6日定信,1986年2月20日初收,5月17日末收)和市郊三元 This test is based on non-toxic high-fat film can prevent a variety of plant fungal diseases reported to carry out.

The control of late blight and leaf mold of tomato was equivalent to that of common pesticide Qing bacteria, increase rate of about 20%. This provides a method for pollution prevention and disease prevention, which deserves further demonstration and promotion. Materials and Methods of Test (I) Test Materials 1.
