Weed killer for lawns comes either ready mixed and ready to use or in a concentrate for dilution with water.
NB Scotts have renamed Verdone as Weedol Lawn Weedkiller. Just as good but now a confusing name!
For complete weed control a concentrate will do as good a job as ‘ready to use’ and vice versa. Use them according to the kind of treatment required. You may have noticed that weed killers are not made of the same chemicals. A lawn weed killer is a carefully selected group of active ingredients designed to kill a certain group of creeping and broad leaved weeds. Not all weed killers will kill all your lawn weeds hence you need to use a range of active ingredients to give yourself the best chance of good weed control. We have therefore selected two groups of weed killers that offer the broadest range of active ingredients so that if one doesn’t kill a certain weed the other may do. Use one group of chemicals for ‘full lawn treatment’ and the other group for ‘spot treatment’. If you only need to ‘spot treat’ then have two different ones on hand or when one runs out buy a different one to replace it.
When treating new lawns the manufacturers have the following recommendations:
Hopefully it goes without saying that growth should be good and the grass healthy before applying weed killer to the grass and weeds.
Weed killers are herbicides; a type of pesticide used to kill plants. Insecticides and fungicides are also pesticides. When using pesticides always read the label and use them safely.
