Resolute 65 WG Prodiamine Herbicide (Generic Barricade) - Questions & Answers

The first thing you need to know when using an herbicide such as Resolute 65 WG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185- 0.83 oz (0.5 - 2.25 tbs) per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185- 0.83 oz (0.5 - 2.25 tbs) of product with for each 1,000 sq ft area that needs to be treated. Please refer to the product label for full application instructions.

In order for a pre-emergent to be effective on dandelions, it must be applied in late winter. The pre-emergent will prevent the dandelion seeds from germinating and is only effective if used before the dandelion seeds have had a chance to germinate. If you do see dandelions growing after the application of your pre-emergent, then you can spot treat with a selective herbicide that is tolerable on your turf type.

As with any Wettable Granule or Powder, you can use your 30 gallon sprayer, but there is a chance of clogging as it settles. The movement of the mower as you drive around may be enough to keep it agitated in your sprayer but you may have to periodically unclog the filter if the movement is slow or you have a large area to cover that would give it more time to settle. You may want to contact the manufacturer Syngenta, for more information on settling with large tanks when using their product. Syngenta: 1-866-796-4368
