Occurrence and epidemic dynamics of early leaf spot of peanut in Liaoning Province
摘要
Abstract
To guide the control of peanut early leaf spot in fields,the disease damage and the epidemic dynam-ics were studied.The different region and different varieties of peanut leaf spot in Liaoning Province was investiga-ted by the method of five point sampling.A systematical investigation on the disease was carried out in 201 1 and 2012.The results showed that the diseases have occurred in different peanut production areas.Shenyang was the worst infected area and Xingcheng area was less infected.The disease index in 2012 was higher than in 201 1 in most areas.Different varieties had different disease index,the highest disease index was Silihong,the least disease index was Baihuasheng.Through comparing and analyzing,Logistic model could reflect the temporal dynamic of peanut early leaf spot disease well.关键词
