- 摘要:
- 为防治马铃薯早疫病,本试验对4种药剂在3个地区进行田间试验,对马铃薯安全性、产量及成本进行分析。结果表明:70%丙森锌WP、52.5%噁酮?霜脲氰WG、18.7%烯酰?吡唑酯WG、25%嘧菌酯SC在推荐使用剂量范围内对马铃薯早疫病均有一定的防治效果,无药害产生,防效在60.81%~78.60%,马铃薯产值增加97.4~294.4元?667 m-2。4种杀菌剂在推荐剂量范围内对马铃薯安全,防治效果较好,成本较低。
- Abstract:
- In order to control early blight of potato,the effects of 4 fungicides on potato′s safety,control efficacy and yield were determined by field trials at three areas.The results showed that propineb 70% WP,cymoxan?famoxae 52.5% WG,dimethomorph?pyraclostrobine 18.7% WG and azoxystrobin 25% SC used in the leaves were safety,effective and no phytotoxicity for potato.The control effect of potao early blight was 60.81%-78.60%,the output value increased 97.4-294.4 yuan?667 m-2.Four fungicides used in the leaves were safety and no phytotoxicity for potato.
