摘要
番茄病毒病是番茄生产过程中主要病害之一,对番茄产量及质量造成严重影响。为探明氨基寡糖素对番茄病毒病的具体田间防治效果,将2%氨基寡糖素水剂用于防治番茄病毒病,进行田间药效试验。研究结果显示:各处理区间的药效差异极显著;防治番茄病毒病的药效随用药量的增加而提高,推荐使用浓度为300倍;采用喷雾法施药,第一次施药应在发病前夕或发病初期,施药次数为3~4次,每次间隔一周时间。施药次数和间隔期应视病情发展灵活掌握;处理后的番茄生长正常,未发现药害。
Tomato virus disease is one of the main diseases of tomato, which seriously affects the yield and quality of tomato. In order to find out the specific field control effect of amino oligosaccharide on tomato virus disease, 2% amino oligosaccharide water was used to control tomato virus disease. The results showed that there was a very significant difference in the efficacy of each treatment area. The efficacy of tomato virus disease was increased with the increase of the dosage. The recommended concentration was 300 times. Spray was used for the first time. The first application should be 3~4 times at the beginning of the disease or at the beginning of the disease. The application times and interval should be controlled flexibly according to the development of the disease;the tomato after treatment grew normally and no harm was found.
