OSR Herbicides Guide
A guide to help farmers and agronomists understand how best to reduce the risk of oilseed rape herbicides reaching water.
The guide is split into the following 12 sections. In addition, there is a gross margin calculator to show the profitability of your rotations.
1. What's the problem?
Detection of key herbicides in drinking water sources could result in restrictions on use and – without the application of best practice...
2. Assessing the risks
Despite taking care, the risks can include yard spills, run-off after heavy rain, losses through deep soil cracks and field drains.
3. Cropping decisions and IPM
Using crop rotation, varietal selection, cultivation, agronomy, forecasting and monitoring tools alongside the prudent use of pesticides.
4. Soil management and cultivations
The effects of soil management on the speed of pesticide movement from soil to water vary considerably.
5. Drilling and crop establishment
A wide range of establishment methods are used for winter oilseed rape in the UK, which can affect the risk of herbicides reaching water...
6. Weed control and product choice
The current choice of herbicides is already limited. Therefore, care is needed both when choosing and using products to minimise the risk.
7. Herbicide filling & handling best practice
A small splash, sprayer foam, even the washings from a single foil cap, can enter water courses. Observing best practice in filling and h...
8. Herbicide application
Following best practice when applying herbicides to oilseed rape will ensure optimum performance from the products and minimise the risk...
9. Reducing run-off with grass buffer strips
Grass buffer strips are areas of land with permanent vegetation that slow run-off and allow time for drainage. Usually established beside...
