| 摘 要： | 通过系统调查研究了驻马店烟区主要病虫害发生规律.结果表明,烟蚜在3月中旬迁飞,6月底前结束,于5月上旬、月底形成2个高峰;病毒病正常年份发病率在5％左右、病指在3左右,遭遇低温、干旱等不利自然条件时,发病程度较重.黑胫病于6月初期开始发生,7月中旬基本稳定,发病程度因降雨量多寡差异较大,整体病害发生为零星分布;赤星病多发生在7月中旬,病株率相对偏高,但病指较低,中下部叶片感病较少,主要发生于上部6片叶,总体表现为发病较轻. |

| Abstract: | Through investigation,the occurrence regularity of the main tobacco diseases and insect pests in Zhumadian was studied.The results showed that the migration of tobacco aphid began in mid March,the end of June,the formation of two peaks in early and the end of May.The incidence rate of virus disease was around 5％ in normal years,the disease index was around 3,encountered low-temperature,drought and other unfavorable natural conditions,the extent of the disease was relatively heavy.Black shank began in the early June,was stable in mid July.The extent of the disease was different due to the rainfall,the overall disease sporadically distributed.Brown spot disease occurred in the mid July,the rate of diseased plants was relatively high,but lower disease index.The middle and lower leaves were susceptible less,mainly occurred in the upper 6 leaves,The overall incidence was comparatively lighter. |
