Direct contact herbicide application can be achieved by

✅ EXPLANATION: Direct contact herbicide application refers to applying herbicides directly to the target weed, minimizing the amount of herbicide that comes into contact with non-target plants and soil. This method is often used for spot treatment of weeds in areas where desirable plants are present.
• Re-circulating sprayer: This type of sprayer has a pump that continuously re-circulates the herbicide solution through a boom or hand-held wand. The operator can direct the spray directly onto the target weeds.
• Weed wick wiper: This is a device that consists of a cloth or rope that is soaked in the herbicide and then dragged across the ground. As the wick passes over the weeds, the herbicide is transferred to the weeds.
• Roller applicator: This is a device that consists of a roller covered with a material that is absorbent to herbicides. The roller is dipped in the herbicide solution and then rolled over the weeds. As the roller passes over the weeds, the herbicide is transferred to the weeds.
