摘要: 【目的】 筛选防治新疆棉花苗期主要病害和虫害、促进作物出苗和生长等功能的棉花种衣剂。【方法】 制备种衣剂,进行棉种包衣田间试验,评价其田间生物学效应。【结果】 供试的11种种衣剂中,17.2%吡虫啉·萎锈灵·福美双种衣剂表现最佳,对棉花苗期立枯病和红腐病的防效分别为72.28%、74.44%,对蓟马、地老虎防效分别为83.33%、85.00%,处理棉田出苗率、株高、根长、茎粗、单株鲜重、单株干重、产量较对照处理分别提高7.89%、16.04%、11.18%、5.03%、68.44%、124.04%和13.98%。【结论】 17.2%吡虫啉·萎锈灵·福美双种衣剂可用于新疆苗期主要病虫害的防控,较常规药剂喷施显著降低化学农药使用量。

Abstract: 【Objective】 This project aims to screen new seed coating agents which can control the main diseases and insect pests at the seedling stage in Xinjiang, and promote cotton emergence and growth at the same time.【Methods】 Through the preparation of seed coating agent and the field experiment of cotton seed coating, the biological effect of cotton seed coating in the field was evaluated.【Results】 17.2% of imidacloprid·carboxin·hiram was the best in the field tests among eleven kinds of seed coating agents. The controlling effects on cotton damping off and cotton Fusarium red rot at the seedling stage were 72.28% and 74.44%, respectively. The controlling effect on the thrips was 83.33%, and the controlling effect on the cutworm was 85.00%. Compared with CK, it was showed that cotton seedling emergence rate, plant height, root length, stem diameter, fresh weight per plant, dry weight per plant, and the yield of 17.2% of imidacloprid·carboxin·hiram seed coating treatment were increased by 7.89%, 16.04%, 11.18%, 5.03%, 68.44%, 124.04%, 13.98% higher, respectively.【Conclusions】 17.2% of imidacloprid·carboxin·hiram seed coating agent could be used for controlling cotton diseases and insect pests at the seedling stage in Xinjiang. Compared with conventional pesticides sprayed, the dosage of chemical pesticides was reduced significantly.
