Selective Weed Killer for Paddocks

Weeds in paddocks and grassland needs to be kept on top of. Not only do weeds reduce productivity and yield but many weeds are poisonous and pose a danger to grazing animals. For these reasons it is essential that control is gained.

ProGreen offers selective weed killers that allow you to control specific weeds while leaving vital grazing land unharmed making it the ideal solution.

It is important to remember that if you are treating paddocks that have grazing animals present that you leave a grazing animal exclusion period of 7-14 days (check the product label for the recommendations for each product). If you are treating areas where poisonous weeds such as ragwort have been present then it is important that you DO NOT allow animals to return to the area until the weed has completely died and been removed.

What Equipment Should I Use?

When it comes to applying selective weed killers it is important to check the approvals to see what equipment you are allowed to use to apply them. Some products only have approval to be applied via a handheld applicator/knapsack sprayer, some only via a boom sprayer and others have approval for both methods. Whichever way you use, it is vital that you are wearing the correct PPE to protect yourself from the chemicals that you are spraying.

If you are looking for a way to easily see where you have sprayed to help avoid under/overdosing then we would advise using a marker dye. These products are simply mixed in with the spray solution and when you spray you will be able to see where you have been as a result of the colour indicator.

Frequently Asked Questions

Q. When should I use these weed killers?

A. Selective weed killers should be used when the plants are actively growing as this is the best time to treat most weeds. For more guidance on the best times to treat specific weeds, take a look at our weed control guides.

Q. How soon can horses graze after I use a weed killer?

A. Horses are allowed back into treated grazing land 7-14 days after application. This should be checked on the individual product label to get the specific recommendation. If you have treated land where poisonous weeds were present then the grazing exclusion period MUST be extended to make sure that the animals are not consuming any of the dangerous weeds.
