我省于1965年在湛江地区发现花生锈病,1970年后逐渐蔓延,以致部分地区的花生遭受不同程度的损失。据我们接种测定,锈病为害越早,损失越重,花期减产49％,针期减产41％,结荚期减产31％,结荚中期减产18％,成为花生高产稳产的主要障碍。近年来,我们认真总结群众经验,与贫下中农共同摸索锈病的发生规律和防治方法,认为必须采取以栽培防病为基础,推广抗病品种为中心,适期喷药防治为辅的综合措施,就可以收到良好的防治效果。
Pear rust was found in Zhanjiang in 1965 in our province, and gradually spread after 1970. As a result, peanuts suffered losses in some areas. According to our inoculation assay, the earlier the rust damage, the heavier the loss, 49% flowering reduction, needle reduction of 41%, pod reduction of 31%, pod mid-term reduction of 18%, become the main obstacle to high yield and stability of peanuts. In recent years, we conscientiously summed up the experience of the masses and worked with the poor peasants to find out the law of occurrence and control of the rust disease. We thought that we must take comprehensive measures that are based on the cultivation of disease prevention, promotion of disease-resistant varieties as the center, supplemented by timely spraying prevention and control, You can receive a good control effect.
