鉴定种衣剂对棉花苗期病虫害的防治效果,并肯定其利用价值,为大面积推广种衣剂技术提供科学依据。此为本试验之目的。一、材料与方法供试品种为晋棉7号。该试验为露田直播,随机排列,重复三次。小区面积5厘,长方形,每区175株,四边设保护行。试验设五个处理: (1)光籽种衣剂处理区:每市斤种衣剂1号处理光籽种子25斤。该农药含呋喃丹有效成分24%、多菌灵12%。药种比例为1:0.5:100。 Identification of seed coating on cotton seedling pest control and affirmation of its value, for large areas to promote seed coating technology to provide a scientific basis. This is the purpose of this experiment. First, materials and methods for the test varieties Jinmian 7. The experiment was live on the field, arranged randomly and repeated three times. Area of ​​5 centimeters, rectangular, 175 per district, set aside four protection line. The experiment set five treatments: (1) light seed coating agent treatment area: per kilogram of seed coating agent No. 1 treatment of light seeds 25 kg. The pesticide contains carbofuran active ingredient 24%, carbendazim 12%. Medicine ratio of 1: 0.5: 100.
