家蚕的白僵病、绿僵病等真菌性病害在我省发生普遍,发病的轻重与气象条件有关。在发生不重的年份,用常规措施即能控制,但遇到大流行年份,如不采用高效药物将难以控制,给蚕茧生产造成巨大损失。我们研制的蚕用添食防病新药克氯素,已推广至全国十多个省市的蚕区,各地均反映防病效果显著。在此基础上,我们又研制成功了与克氯素药效相当,成本降低的克红素,现将其研究和应用结果报告如下:
Bombyx mori silkworm, green stiff stiff disease and other fungal diseases occur in our province generally, the severity of the disease and weather conditions. In the non-heavy year, control can be achieved by conventional measures, but in the year of pandemic, it would be difficult to control the use of highly effective drugs, causing huge losses to cocoon production. We have developed silkworm add Tim disease prevention and treatment of new drugs, chlorin, has been extended to more than 10 provinces and cities in the sericulture area, all reflect the significant effect of disease prevention. On this basis, we have successfully developed and grams of chlorine similar efficacy, cost reduction of the grams of red pigment, now its research and application results are reported as follows:
