Grass Out Max (Clethodim Herbicide) can only be used only in non bearing vineyards per the product label. Non-bearing fruit and nut crops are plants that will not bear fruit or nuts for at least one year following AGRISEL GRASSOUT MAX HERBICIDE application.
Grass Out Max (Clethodim Herbicide) is designed specifically for killing grassy weeds including fescue in ornamental areas without harming desirable shrubs and roses, it is not for use in lawns at all.
Since poa annua is so closely related to cool seasons grasses, like fescue and ryegrass, there are not any herbicides that can be applied to kill the poa without also harming the fescue and ryegrass. We do have one product called Prograss EC Herbicide, but it is very expensive. We recommend spot treating the poa annua with a glyphosate product and then just reseeding those areas.
Unfortunately, we do not carry any herbicides that are labeled to kill zoysia in a tall fescue lawn. You will either need to spot-treat the unwanted grasses with a glyphosate product like Roundup Quik Pro and reseed. Fusilade II can be used to get rid of Bermuda grass in tall fescue. You will also need to add a nonionic surfactant for best results. Please be advised that Bermuda grass is extremely difficult to control and you will likely need to make several applications. With Fusilade II Herbicide, it is recommended to apply the product in the early morning hours or late evening hours when the temperatures are below 85 degrees Fahrenheit.
Grass Out Max (Clethodim Herbicide) will likely kill your grass since it is only safe for ornamentals not for use on turfgrass areas. Image Kills Nutsedge Concentrate & Certainty Herbicide are both labeled to control poa while being safe on Zoysia lawns

You could potentially mix Grass Out Max (Clethodim Herbicide) and another herbicide, however due to the number of restrictions, it is generally easier and more effective to apply such products separately.

If grass regrowth occurs, an additional application may be necessary.
Grass Out Max is for use on clover grown in Idaho, Oregon, and Washington only, and at rates of 6 - 16 oz per Acre in those states.

A non ionic surfactant is an adjuvant (or sticking agent) that helps the product it is mixed with to stick to the surface/plant that is sprayed. This helps to increase the effectiveness of the product that it is mixed with. Not all products are labeled to be mixed with a surfactant, so it is important to review the product labels of the items you are using to ensure you are following the instructions for best results.
Grass Out Max (Clethodim Herbicide) recommends using a non ionic surfactant or crop oil concentrate for best results. We do not recommend using Dawn Soap as an alternative as that would be using the products off label, and there is no recommended/instructed amount to even use to see if it would be effective.Grass Out Max can be used on squash, cucumbers, sweet potatoes, okra . Please see the product label for a full list of tolerable vegetables.
While Grass Out Max (Clethodim Herbicide) should not have any corrosive effects on metal or surfaces and there is no information on the SDS Sheet, we would recommend contacting the manufacturer directly for specific information on the chemical make up of their product.
