Abstract
[Aims] This study aims to adopt the fan-shaped spray technology in the field trials for controlling outbreak of Aphis gossypii to reduce the dose of acetamiprid and water. [Methods] Using single factor randomized block design of experiment, the control experiments were conducted based on two field spray and tank-mix adjuvant. [Results] The field result indicated that the control effect of A. gossypii reached 95.2% after 3 days and 98.6% after 7 days using the fan-shaped nozzles when the spray volume maintained and water volume decreased by 50%; the effect against A. gossypii was above 97.1% after 3 days and 100% after 7 days when added the tank-mix adjuvant into pymetrozine with the decrease of 20% spray volume. [Conclusions] The fan-shaped nozzles instead of conical nozzles improved the effect of the liquid atomization, could save water 50% in production. Tank-mix adjuvant increased the surface tension of the acetamiprid solutions on the leaves and acetamiprid was reduced by 20%.
