摘要
为探讨药剂树干注射对松树松材线虫的林间防治效果;于广西钦州某国有林场选择6块100株胸径约25 cm的松树进行了试验,共设置了6个小组,每组100株,分别为对照组、20%阿维菌素乳油组、0.3%苦豆碱水剂组、10%甲维·吡虫啉可溶液剂组、5%高效氯氰菊酯乳油组、5%啶虫脒注干剂组;对照组注射等量药剂的清水,其余的药剂组均注射对应的化学药剂;于2020-2023年对试验松树的枯死情况进行调查,同时每年10月底统计墨天牛的诱捕数量。结果表明:以20%阿维菌素乳油组的防治效果最优,该组2020年、2021年、2022年和2023年的林间防治率分别为80.74%、78.48%、74.06%和70.57%,防治率均高于70%,随着年限的延长各个小组的林间防治率均逐渐下降,20%阿维菌素乳油组的防治率均显著的高于其他各个药剂组(P<0.05);防治效果其次的为10%甲维·吡虫啉可溶液剂组,10%甲维·吡虫啉可溶液剂组2020年、2021年、2022年和2023的防治率均高于5%高效氯氰菊酯乳油组;5种树干注射的药剂诱捕松墨天牛数量比较为:5%啶虫脒注干剂组>0.3%苦豆碱水剂组>10%甲维·吡虫啉可溶液剂组>5%高效氯氰菊酯乳油组>20%阿维菌素乳油组,其中20%阿维菌素乳油组、5%高效氯氰菊酯乳油组诱捕松墨天牛数量差异不显著(P>0.05);0.3%苦豆碱水剂组和5%啶虫脒注干剂组诱捕松墨天牛数量差异不显著(P>0.05),但是均显著高于20%阿维菌素乳油组、5%高效氯氰菊酯乳油组(P<0.05);以20%阿维菌素乳油树干注射效果最佳,其次为5%高效氯氰菊酯乳油。
In order to explore the forest control effect of pesticide trunk injection on pine wood nematodes in pine trees,in this experiment,6 pieces of 100 pine trees with a diameter at breast height of about 25cm were selected from a state-owned forest farm in Qinzhou,Guangxi.A total of 6 groups were set up,with 100 trees in each group,including a control group,a 20%avermectin emulsion group,a 0.3%bitter bean alkaloid aqueous group,a 10%methoxazole imidacloprid soluble group,a 5%high-efficiency chlorpyrifos emulsion group,and a 5%imidacloprid injection dry group;The control group was injected with an equal amount of water,while the other drug groups were injected with corresponding chemical agents;a survey on the withering and death of experimental pine trees from 2020 to 2023 is conducted.At the same time,the number of lured black longhorn beetles at the end of October each year is counted;The control effect of the 20%avermectin emulsion group was the best.The forest control rates of the group in 2020,2021,2022,and 2023 were 80.74%,78.48%,74.06%,and 70.57%,respectively,with control rates all higher than 70%.As the years increased,the forest control rates of each group gradually decreased,and the control rates of the 20%avermectin emulsion group were significantly higher than those of the other drug groups(P<0.05);The second most effective group in terms of prevention and control was the 10%metformin imidacloprid soluble group.The prevention and control rates of the 10%metformin imidacloprid soluble group in 2020,2021,2022,and 2023 were higher than those of the 5%high-efficiency chlorpyrifos emulsion group;Five types of tree trunk injection drugs were used to trap pine black beetles.The 5%imidacloprid injection group>0.3%bitter bean alkali water group>10%methomyl imidacloprid soluble group>5%high efficiency chlorpyrifos emulsion group>20%avermectin emulsion group were used.Among them,there was no significant difference in the number of pine black beetles captured between the 20%avermectin emulsion group and the 5%high efficiency chlorpyrifos emulsion group(P>0.05);There was no significant difference(P>0.05)in the number of pine black beetles captured between the 0.3%bitter bean alkaloid water group and the 5%imidacloprid injection dry group,but both were significantly higher than the 20%avermectin emulsion group and the 5%high-efficiency chlorpyrifos emulsion group(P<0.05);The best effect is achieved by injecting 20%avermectin emulsion into tree trunks,followed by 5%high-efficiency chloramphenicol emulsion.
