应用化学药剂防治林木病害是保护森林资源的主要措施之一。为了改制延用的五氯酚钠烟剂,扩大杀菌烟剂品种和探索杀菌油剂超低容量喷雾防治林木病害的可能性,我们改制出了5种五氯酚钠烟剂,研制出了5种杀菌烟剂和5种杀菌油剂,并用这些药剂对落叶松早期落叶病和杨树灰斑病进行了药效试验。现将部分试验结果总结如下:
The application of chemical agents to control forest diseases is one of the main measures to protect forest resources. In order to reform the extended use of pentachlorophenol sodium smoke agent to expand the varieties of bactericidal smoke and explore the possibility of ultra-low volume spray sterilizing spray disease prevention and control of trees, we transformed five kinds of pentachlorophenol sodium smoke agent, developed a 5 Fungicides and five kinds of bactericidal oil, and used these medicaments to test the effects of early deciduous larch and poplar gray spot. Now part of the test results are summarized as follows:
