Inversion and drift: Risk factors

Air temperature inversions – when air temperatures actually increase as you get higher above the ground – create ideal conditions for tiny spray droplets to become suspended in the air and drift considerable distance from their target. This cool air mass hovering near the ground can flow like water to valleys and lower areas. Early…

Rain and wind have delayed spray operations, leaving some very short windows to get important herbicide spraying done. Here are some drift management tips that can work in combination to help reduce the risk of drift and perhaps make those short spray windows just a little bit longer. 1. Do not spray in winds above…

Late sprays. Second applications applied late can reduce profitability it two ways: A competitive crop growing ahead of the weeds may not need a second application. A late application can cause a surprising level of hidden damage to canola plants, setting back yield potential. Read more More drift. Wind and rain have reduced the opportunities…

Wind can delay timely spraying. If it’s too windy (more than 20 km/h), the sprayer will probably have to sit idle, but when wind is 10 to 20 km/h, use these tips to improve performance and reduce drift… Use low-drift nozzles. Increase water volumes to improve coverage with large droplets. Find a nozzle that can…
