Spray of Chemicals as Affected by Different Parameters of Air Assisted Sprayer: A Review

In orchards, day by day productivity reduces by diseases. To prevent the effect of these diseases, spraying of pesticide was one of the options. There were several methods for pesticide spraying, one of the efficient method practiced in spraying by air assisted sprayer, which reduced losses during spraying and cover more tree canopy area. In this sprayer, different parameters were affecting spraying such as blower speed, operating speed of sprayer, operating pressure in sprayer and pesticide applications. Therefore the study was conducted to find out the effect of different parameter on spraying. The operating speed of sprayer showed significant effect on spray droplets deposition, distribution by conspicuously greater at lower operating speed. In air assisted sprayer, increasing blower speed significantly increased drift force and increased tree canopy area in spraying. The efficiency of spray deposition increased with increase in blower speed. The conveying efficiency of spray particles, penetration and distribution of pesticide were increased with increase in operating pressure. The performance of sprayer was found better with increase in operating pressure (1 to 15 kg/cm2) of spraying.
