Preliminary Study on the Aerial Control Techniques of 20%Cyproflanilide Suspension Concentrate Against Chilo suppressalis in Early Rice
In order to explore the aerial control efficacy of 20%Cyproflanilide suspension concentrate against Chilo suppressalis in early rice,a field experiment was conducted using P100PRO plant protection unmanned aircraft as control tools,with different application rate per unit area and the commercial formulation dosage and set operating parameters in 2023.The results showed that,under the premise of applying the rated commercial formulation dosage per unit area,the control efficacy on Chilo suppressalis did not always increase with the increase of liquid dosage,and the optimal liquid dosage was about 39.00 L/hm2.Under the premise of applying the rated liquid dosage per unit area,the control effect on Chilo suppressalis increased with the increase of the commercial formulation dosage per unit area,and the optimal commercial formulation dosage per unit area was about 378.69 mL/hm2.The control efficacy after one application could last for about 15 days.
