Weedicides

Weedicides 

Weedicides are pesticides or weed killers used to kill unwanted plants.

Weedkillers are chemical-based solutions that are specifically designed to target different types of weeds in the most effective way possible while causing no harm to the rest of the crop. They are commonly used in agricultural activities to increase output. Weedicides are highly water soluble and naturally persistent.

Measures to be taken:

Weedicides and herbicides should be used with caution.

1) The appropriate proportions of weedicides or herbicides for the various crops must be followed. 

2) Do not use weedicides or herbicides that have expired. Check the manufacturing date and expiration date of any weedicides or herbicides you intend to purchase carefully. 

3) Use a different Knapsack pump to spray weedicides or herbicides. 

4) Make sure the soil is moist, gritty, and lump-free before spraying weedicides or herbicides.

 5) Apply weedicides or herbicides when there are no strong winds present and no chance of precipitation as well.

6) As you are spraying, step backward to avoid stepping on any areas where weedicides or herbicides have been applied

7)Don't cultivate anything in the fields for at least 21 days after applying weedicides or herbicides like glyphosate. 

8) Use a consistent pressure to evenly spray the herbicides or weedicides across the entire field. Use a flat pan or flood jet nozzle for even spraying. 

9) When spraying standing crops, be careful to avoid accidentally spraying other crops. Use a hood to appropriately focus the spray in order to do this. 

10) Use the appropriate herbicides or weedicides for the situation, the type of weeds, and the weather to control weeds. 

Herbicides and weedicides should not be used frequently or excessively. Use vermicompost and compost manure in soil that has been sprayed with herbicides or weed killers.

Most Commonly used :

The five most often used weedicides are as follows:

1. 2, 4 Dichlorophenoxy Acetic Acids: 

This systemic herbicide eliminates the majority of broadleaf weeds by promoting unchecked growth. However, it is ineffective on the majority of grasses, including cereal grass and turf grass. It came into being in the 1940s.

2. Naphthalene acetic acid, 

also referred to as naphthalylacetic acid It is utilised in low quantities since it has a little hazardous effect. In the auxin family, it is also employed as a synthetic plant hormone.

3. To control grassy and broadleaf weeds, atrazine is frequently applied to corn, sugarcane, and sorghum fields before or after planting.

4.Glyphosate SL: 

This systemic weedicide and agricultural desiccant has a broad spectrum. It functions by blocking the enzyme 5-enolpyruvylshikimate-3-phosphate synthase found in plants. It is primarily taken up by the leaves.

5. Metribuzin WP:

It is absorbed primarily through aerial application and by the roots.
