Weed Management in Mentha Crop

Mentha, also known as mint, is cultivated on a large scale in India due to its medicinal properties. Its cultivation is primarily done for the oil obtained from its leaves. However, like other crops, mint cultivation is also affected by weeds, pests, and diseases. The problem of broad-leaf weeds and narrow-leaf weeds in mentha crops is common, which reduces the oil content in the crop and deprives farmers of profits. For more information on the losses caused by weeds in mentha crops and how to control them, please read through.

Damage Caused by Weeds in Mentha Crops

• Reduction in Oil Quantity: The quality of the crop is severely affected due to weeds. Along with this, there is a reduction in the quantity of oil in its leaves.
• Deficiency of Nutrients: Weeds present in the field absorb nutrients from the soil, depriving the crops of adequate nutrition.
• Outbreak of Diseases and Pests: Weeds contribute to the spread of various fungal diseases and pests, resulting in adverse effects on the crop.
• Crop Yield Reduction: Weeds in the field can decline in the crop's production, leading farmers to face losses instead of profits.
• Increased Costs: The use of weedicides/herbicides contributes to a rise in agricultural costs. Additionally, controlling pests and diseases through various chemicals also increases expenses.

Different Methods of Controlling Weeds
