中文摘要: |
通过研究5种低毒、低残留的化学杀虫剂对红色砂梨上西花蓟马的防治效果,为云南无公害绿色特色水果的生产提供指导。本试验选用80%敌敌畏乳油、2.5%高效氯氟氰聚酯水乳剂、20%吡虫啉水乳剂、5%啶虫脒乳油和30%30%氯虫•噻虫嗪悬浮剂5种化学杀虫剂进行田间试验。结果表明:5种化学杀虫剂对梨树蓟马均具有较好的防治效果,从药后第1天到第7天,防效都达到了70%以上。以氯虫噻虫嗪效果最好,药效持续时间长。 |

Pesticides used for control of western flower thrips (Frankliniella occidentalis) attacking Yunnan red sand pear were screened in the field. Results showed that five pesicides (80% dichlorvos EC, 2.5% lambda-cyhalothrin WE, 20% imidacloprid WE, 5% acetamiprid EC and 30% Durivo(chlorantranilip and thiamethoxam) SC) have good control efficiency to thrips on pear, with a controlling efficiency of 70%or more after 1 days of application. |
