Gordon's Brush Killer kills annual, perennial and woody weeds via foliage. For effectiveness, the manufacturer delimits dilution guidelines for the user. The user must dilute the product according to the type of weed treated. After several days, the weed foliage turns yellow, then subsequently browns and dies. The manufacturer says you should not use Gordon's Brush Killer on windy days, nor just prior to rain or irrigation. Wind may carry the weed killer to desirable plants and crops. Rain or irrigation removes the weed killer from the weed foliage and reduces its effectiveness. Always wear safety gear when handling or spraying Gordon's Brush Killer.
