Peas and beans are often referred to in the same breath as they are the most common legume break crop. However from an application point of view the crops are very different as bean canopies are very open in comparison to peas. So larger drops are needed to penetrate the thicker canopies when the crop is at later growth stages.
Peas
Timing | Water volume (l/ha)* | Forward speed | Best nozzle | In compromised conditions |
---|---|---|---|---|
Pre-em herbicides | 200 | 10-12 km/h | 3D nozzle alternating forwards and back | 90% Drift Reduction Nozzles |
Post-em herbicides | 100 and above | 12-14 km/h | 3D nozzle alternating forwards and back | 3D nozzle (worst case AMISTAR nozzle) |
Fungicides | 200 | 12km/h or slower | 3D Nozzle alternating forwards and back | AMISTAR Nozzle, all facing backwards when operated at 1.5 bar pressure |
Insecticides | 3D Nozzle alternating forwards and back |
Beans
Timing | Water volume (l/ha)* | Forward speed | Best nozzle | In compromised conditions |
---|---|---|---|---|
Pre-em herbicides | 200 | 10-12 km/h | 3D nozzle alternating forwards and back | 90% Drift Reduction Nozzles |
Post-em herbicides | 100 and above | 12-14 km/h | 3D nozzle alternating forwards and back | 3D nozzle (worst case AMISTAR nozzle) |
Fungicides | 100 and above** | 12-14 km/h | 3D Nozzle alternating forward and backward along the boom for improved coverage | AMISTAR nozzle when operated at 1.5 bar pressure. |
Insecticides | 100 and above** | 12-14 km/h | 3D Nozzle alternating forward and backward along the boom for improved coverage | AMISTAR nozzle when operated at 1.5 bar pressure |
*Please refer to the product label for water volumes. Growers can reduce water volumes as long as they adhere to the HSE/DEFRA Code of Practice for Using Plant Protection Products. Please refer to paragraph 4.6.4, page 81 of the HSE/DEFRA Code of Practice for Using Plant Protection Products.
** In denser crops coverage can be increased by using higher water volumes, do not exceed 200 l/ha.
