4个番茄品种对细菌性斑点病田间抗性评价及摘叶法防治技术初探

摘要

Test by comparing 4 varieties of tomatoes disease resistance and disease in the clinical characteristic, and adopt disease leaves removal method of prevention and control the disease. The results showed that the Rabbi resource performed better disease resistance, tomato bacterial speck disease of disease severity in plant were lower > middle > upper. Preventing disease with 300 times liquid of 20%thiodiazole-copper SC, supplemented by artificial removal of lower ill leaf measures can significantly improve the effect.%对云南热区4个番茄品种进行了细菌性斑点病的田间抗性评价和发病特点调查，同时评价了人工摘除病叶法对该病的防治效果。结果表明，拉比品种抗病性优于其它3个品种，同一品种植株上各部位发病严重程度依次为下部＞中部＞上部。用20%噻菌铜SC300倍液进行病害防治时，辅以人工摘除下部重病叶的措施可显著提高病害防治效果。
