摘要
选用了0.5%藜芦碱水剂、0.3%苦参碱水剂、0.5%印楝素水剂、1.5%除虫菊素、5%桉油精水剂对枸杞木虱进行防治;用0.5%藜芦碱、0.3%苦参碱、50%硫磺悬浮剂、0.5%印楝素、1.6%狼毒素、1.5%除虫菊素、5%桉油精对黑果枸杞蚜虫进行防治;用0.5%藜芦碱、0.3%苦参碱对黑果枸杞负泥虫进行防治;用0.5%藜芦碱水剂、0.3%苦参碱水剂、雅氪、满维对枸杞瘿螨进行防治。结果表明:在黑果枸杞防治中,0.5%藜芦碱对枸杞木虱的卵及若虫防效最好,其中,藜芦碱72h后防效可达80%。5%桉油精对枸杞蚜虫防效最好,药后72h达到83.88%,效果好于其他药剂。枸杞负泥虫防治中,0.5%藜芦碱防效最好,药后48h达到了97.55%;枸杞瘿螨防治中,24h后0.5%藜芦碱防治效果可以达到95%,水剂优于可溶剂。
Lycium ruthenicum not only has ecological benefits,but also has significant economic benefits.With the increasingly expanded production,the economic loss caused by pests is more and more serious.In order to guarantee the quality of Lycium ruthenicum ,organic production is required.This study chose 0.5% veratrine,0.3% matrine,0.5% azadirachtin,1.5% pyrethrin and 5% eucalyptus oil for Paratrioza sinica;Control of aphids was conducted with 0.5% veratrine,0.3% matrine,50% sulfur suspension,0.5% azadirachtin,1.6% Wolf toxin,1.5% pyrethrin and 5% eucalyptus oil.Using 0.5% veratrine and 0.3% matrine to control the Lema decempuctata.Aceria palida was controlled by 0.5% veratrine,0.3% matrine,krypton (1.5% matrine) and manwei (0.5% veratrine).The results showed that 0.5% veratrine had the best control effect on the eggs and nymphs of Lycium barbarum ,among which the control effect of veratrine after 72 hours was more than 80%.5% eucalyptus oil is best to control aphid,reach 83.88% 72 hours after medicine,the effect is better than other medicament.In the control of Lema decempuctata ,the control effect of 0.5% veratrine was the best and reached 97.55% 48 hours after taking the medicine.In the control of Aceria palida ,the control effect of 0.5% veratrine after 24 hours can reach more than 95%,Water is more effective than solvent.The results showed that the effective pesticide against pests of Lycium ruthenicum could provide practical guidance for pest control during the production of organic agricultural products.It can also be used for reference when similar pests occur in other agricultural products.
