摘　　要：通过田间调查和室内抑菌试验发现哈尔滨市郊区已出现了抗多菌灵兼抗甲托的灰霉菌抗性菌株。复合药肥对灰霉菌有很好的抑制作用 ,对番茄灰霉病的田间防治效果达 80 %以上 ,同时能兼防番茄叶霉病。在番茄作果期和青果期喷施复合药肥 ,能够提高番茄叶片光合速率 30 %～ 40 %。The resistant strains of Botrytis cinerea to carbendazim and thiophanate-methyl were discovered in Harbin outskirts by field investigation and controlling fungus test in lab. Multiple fungicides fertilizers (derived from fungicide and fertilizer) made by ourselves have good controlling effect to Botrytis cinerea. The effect of 1%~2%compound was a hundred percent to controlling Botrytis cinerea after 48 hours and 72 hours in lab , eighty percent to controlling grey mould diseases in field. They also have a good effect to controlling the leaf mould disease. We sprayed the compound at green fruit stage and fruit setting stage on tomato. Photosynthetic efficiency of the leaf increased by 30%~40%.
