Vegetables Application

Carrots 


Carrot crops are easy to cover when they are small however it is very difficult to achieve good coverage of the crown using conventional technology, especially when the canopy is large.

Water volume
200 l/ha increasing to 300 l/ha as crop grows for increased penetration to the crown.

Nozzle choice
Vertical flat fan 65 degrees 06 for lower water volumes and 08 for higher. Avoid bubble jets if penetration to the crown is required.

Application speed
5-16 kph depending on weather and travelling conditions. Water volume can also be manipulated through forward speed as appropriate for the canopy size.

Brussels Sprouts


Recommendations vary depending on the size of the crop at the time of application. Early herbicides can be applied using conventional technology however the later fungicide applications can have their effect maximised on the buttons by the specific recommendations below.

Water volume
Small: 100-200 l/ha
Full canopy: 300-500 l/ha

Nozzle choice
Small: AMISTAR nozzle (size depending on volume but 025 would be best for 100l/ha at 12kph, 3bar).
Full canopy: Twin Cap Angled sprays are recommended with a combination of a conventional nozzle at the front and an air induction nozzle such as the AMISTAR at the rear.

Application speed
5-12 kph depending on water volume and application conditions.

Cabbages


Field trials have shown that tailored application advice will improve efficacy of products at different timings. For cabbages this is defined as when the crop are small and when they are hearted.

Water volume
Small: 100-200 l/ha
Hearted: 300-800 l/ha

Nozzle choice
Small: AMISTAR nozzles (choose appropriate size for desired output and forward speed).
Hearted: 65 degree Syngenta Vegetable Nozzle, use the 06 or the 08 depending on the output and forward speed required.

Application speed
5-12 kph depending on water volume and application conditions.

Winter and Spring Field Beans


Peas and beans are often referred to in the same breath as they are the most common legume break crop. However from an application view point the crops are very different. Bean canopies are very open compared to peas so bigger drops are able to penetrate.

Water volume
100 l/ha

Nozzle choice
AMISTAR nozzle or flat fan.

Application speed
Max 12 kph.

Peas


Peas and beans are often referred to in the same breath as they are the most common legume break crop. However from an application view point the crops are very different. Pea canopies are very dense compared to beans so smaller drops are more appropriate to blow under the top leaves.

Water volume
200 l/ha

Nozzle choice
Twin caps or the Syngenta potato nozzle.

Application speed
Max 12 kph.

Please note that for any pre emergence applications (usually herbicide, irrespective of crop) consider using the angled DEFY nozzles alternating down the boom forward and backwards to increase coverage, especially important in cloddy seedbeds.
