| Abstract:
A significant amount of the pesticides are not utilized when the target is missed causing a possible negative effect on environment. By using Anti Drift spraying heads evaporation and drift can be decreased, as the ratio of droplets below 100 micron of size is half of that with traditional nozzles. Losses in spray getting to the soil depends on the system and design of spraying machine as well as the plant characteristics. In vegetable plantations losses varied between 3–10%. Using a closed type spraying machine (spraying tunnel) can decrease the spray reaching the soil in grape plantations. By using the appropriate type of machine and settings so that the extent of losses can be considerably reduced and acceptable protection can be achieved. | |
