Variation of Herbicide Active Ingredients at The Right Dosage!

Methods for Controlling Weeds Using Various Herbicide Active Ingredients and Their Dosages

Weeds are a major issue in agriculture because they compete with crops for water, nutrients, and sunlight, thereby reducing yields. The use of herbicides is an effective method to control weeds. Below are some commonly used herbicide active ingredients, their dosages, and technical application guidelines.

Herbicide Active Ingredients and Dosages

1. Glyphosate

Spectrum of Activity: Non-selective

Dosage: 2-5 liters per hectare

Technical Guidelines:

• Apply when weeds are actively growing.

• The best time for application is in the morning or late afternoon.

• Avoid application on rainy days to reduce the risk of washing away.

2. Paraquat

Spectrum of Activity: Non-selective

Dosage: 1-3 liters per hectare

Technical Guidelines:

• Apply during dry weather conditions.

• Use personal protective equipment (PPE) as this substance is highly toxic.

• Do not apply to soil that will be planted immediately, as residues can harm young plants.

3. Atrazine

Spectrum of Activity: Selective for corn and sorghum

Dosage: 1-3 kg per hectare

Technical Guidelines:

• Apply before or shortly after planting.

• Atrazine is more effective in soil with a pH below 7.0.

• Ensure no runoff potential that could contaminate nearby water sources.

4. 2,4-D

Spectrum of Activity: Selective for corn and cereal crops

Dosage: 1-2 liters per hectare

Technical Guidelines:

• Apply when weeds are young and actively growing.

• Avoid application on desirable broadleaf plants.

• Spray in the morning when the wind is calm to reduce drift risk.

5. Metolachlor

Spectrum of Activity: Selective for corn, peanuts, and soybeans

Dosage: 1-2 liters per hectare

Technical Guidelines:

• Apply before weeds emerge (pre-emergent).

• Mix with water and apply evenly to the soil surface.

• Lightly water the area immediately after application to activate the herbicide in the soil.

Technical Guidelines for Herbicide Application

1. Preparation of Spraying Equipment

• Ensure the sprayer is clean and in good working condition.

• Calibrate the sprayer to ensure the correct dosage.

2. Mixing Herbicides

• Follow the product label instructions to mix with water.

• Use a clean stirrer to ensure a homogeneous mixture.

3. Field Application

• Apply under appropriate weather conditions (not too hot, no strong winds, and no rain forecast for the next 24 hours).

• Use personal protective equipment (PPE) such as gloves, masks, and protective eyewear.

• Spray the herbicide evenly over the target area.

Post-Application Management

• Avoid entering the treated area for at least 24 hours.

• Thoroughly clean the spraying equipment and store it safely.

• Dispose of herbicide residues according to local regulations.

Always follow the product label instructions and good agricultural practices to ensure sustainable farming.

The use of herbicides is an effective method for weed control. Selecting the appropriate active ingredient, using the correct dosage, and applying the herbicide correctly are crucial to achieving maximum results and minimizing negative impacts on the environment and human health.
