Effective Control of White Grub (Humni Pest)
Effective Control of White Grub (Humni) in Crops
What is Humni and why is it harmful?
Humni (white grub) is a pest that lives underground and comes out at night to attack the roots of plants. As a result, the plant's nutrition is cut off, causing it to slowly wither and die. Farmers' observations and reports indicate that the incidence of Humni is significantly higher this year.
Crop Damage Caused by Humni:
-
Roots are eaten, stunting the growth of crops
-
Plants wither and result in a significant yield loss
-
By the time the damage is visible, it is often too late
Two Effective Solutions for Humni Control:
1. Jowar Flour + Cartap Hydrochloride Method (Dry Treatment)
Materials Required:
-
Jowar (Sorghum) Flour – 3 kg
-
Cartap Hydrochloride (or Carbofuran) – 3 kg
Method:
-
Mix both components thoroughly
-
In the evening (around 5–6 PM), spread the mixture manually across the field
-
At night, Humni comes out due to the smell and dies upon contact with Cartap Hydrochloride
Note:
This method is suitable for crops like soybean where drenching is not feasible.
2. Spot Drenching Method (Wet Treatment)
Best suited for crops like cotton and pigeon pea (tur) where drenching is possible.
Dosage per pump:
-
Panda Super – 100 ml
-
Rihash (30% FS) – 50 ml
Method:
-
If a plant appears wilted, mark a 1 to 2-foot area on either side (total 2 to 4 feet)
-
Drench the solution only in that marked area
-
This helps protect neighboring healthy plants as well
Important Points While Controlling Humni:
-
Spot drenching is more effective than spraying
-
Choose treatment based on crop type – use dry treatment if drenching isn’t possible
-
Perform treatment in the evening when Humni is most active
-
Always use the correct chemical dosage
Conclusion:
Controlling Humni depends on timely and precise intervention. By choosing the right method based on crop and field conditions, farmers can effectively manage and prevent Humni damage.
Farmers, take preventive action and safeguard your crops from Humni.
