- 摘要:
- 以33%二甲戊灵乳油为试材，研究了其对甘蓝田杂草的防除效果及适宜剂量，以期为药剂推广应用提供参考依据。结果表明：33%二甲戊灵乳油施用后，对甘蓝无显著药害症状，能很好地防除甘蓝田禾本科杂草和阔叶杂草，33%二甲戊灵乳油有效成份618.8～742.5 g/hm2 ，推荐剂量内对禾本科杂草稗草的株数防效为80.5%～84.7%，鲜重防效为88.1%～91.6%，对阔叶杂草的株数防效为89.6%～94.3%，鲜重防效为93.5%～96.8%。对禾本科杂草和阔叶杂草均表现为鲜重防效高于株数防效。
- Abstract:
- 33% pendimethalin EC was used as test materials,its contribution control effects to weed and dosage were studied,to provide scientific basis for pharmaceutical application.The results showed that 33% pendimethalin EC was safe in cabbage fields after transplanting；it could well control gramineae grassy weeds and broad-leaved weeds.The active ingredients of 33% pendimethalin EC were 618.8—742.5 g/hm2 ，weed control effect to gramineae grassy weeds within the recommended dose was 80.5%—84.7% by plant number，and 88.1%—91.6% by fresh weight.The broad leaf weeds control effect of 89.6%—94.3% by plant number，fresh weight control effect of 93.5%—96.8%.
