Yasuo Homma等曾报告碳酸氢钠对某些蔬菜病害有抑制作用,见里等指出,大豆卵磷酯可以抑制稻瘟病菌的侵入及分生孢子的形成。因此,经生物测定确认有生物活性的食品添加剂可用作农药。为此,将我国广泛应用的食品添加剂对常见植物病害进行植株测定,并探讨其实际应用的可能性。一材料和方法 1.水稻稻瘟病:将病原菌接种在高粱粒培养基中,长满菌丝后洗去菌丝,平铺搪瓷盘内,在25～28℃下保存,两天后即可形成大量孢子,用蒸馏水配制成孢子悬浮液,浓度为100倍显微镜下一视野有30～40个分生孢子。喷雾 Yasuo Homma et al. Reported that sodium bicarbonate has been shown to inhibit certain vegetable diseases. See, for example, that soybean lecithin can inhibit the invasion of Magnaporthe grisea and the formation of conidia. Therefore, biologically active food additives have been confirmed to be useful as pesticides. To this end, the widely used food additives of our plant determination of common plant diseases, and explore the possibility of its practical application. A material and methods 1. Rice blast: the pathogen inoculated in sorghum grain medium, after full of mycelium washed mycelium, tiled enamel dish, stored at 25 ~ 28 ℃, two days to form a large number Spores, formulated with spore suspension in distilled water, the concentration of 100 times under the microscope 30 to 40 cones. spray
