江苏省扬州市邗江区植保植检站等单位使用多旋翼飞行器喷雾防治小麦纹枯病,研究了不同用水量对小麦纹枯病防控效果的影响。结果表明,每667平米用水量2000和2500mL对小麦纹枯病防效最好,药后30天病指防效达75%~80%;用水量750和1000mL对小麦纹枯病防效较差,药后15天病指防效仅有30%左右,药后30天病指防效为60%左右;用水量1250、1500、1750mL对小麦纹枯病防效较好,药后15天病指防效在60%左右,药后30天病指防效在70%左右。
Plant protection and phytosanitary stations in Hanjiang District, Yangzhou City, Jiangsu Province, and other units using multi rotor rotor spray control of wheat sheath blight, studied the impact of different water use on the control of wheat sheath blight. The results showed that 2000 and 2500mL of water per 667m2 had the best control effect on sheath blight of wheat and the control effect was 75% ~ 80% on the 30th day after treatment. The control effects of 750 and 1000mL water on the control of wheat sheath blight were poor , 15 days after treatment, the disease control efficacy was only about 30%, 30 days after treatment, the disease control effect was about 60%; water 1250,1500,1750mL control effect on wheat sheath blight is good, 15 days after treatment of disease Refers to the effectiveness of about 60%, 30 days after the drug control means that the effectiveness of about 70%.
