Controlling Western Black Thrips Naturally with Vermiwash
Share

What is Vermiwash?
Vermiwash is a liquid extract collected after passing water through a column of worm-rich vermicompost. It is rich in plant growth-promoting hormones (like auxins and cytokinins), micronutrients, beneficial microbes, and enzymes. Its composition makes it not just a foliar spray for plant growth but also a natural pest deterrent.
How Vermiwash Helps Control Western Black Thrips
-
Repellent Effect: Vermiwash has a pungent odor and microbial composition that acts as a natural repellent to soft-bodied insects like thrips.
-
Anti-feedant Properties: Spraying vermiwash regularly forms a thin biofilm on leaves, discouraging thrips from feeding and laying eggs.
-
Boosts Plant Immunity: The bioactive compounds and microbes in vermiwash help plants strengthen their defense mechanisms, making them less vulnerable to thrips attack.
-
Disrupts Life Cycle: Frequent application can disturb the thrips' reproduction cycle, gradually reducing their population.
Application Method
-
Dilution: Mix vermiwash with water in a 1:5 ratio.
-
Spray Timing: Spray early morning or late evening, twice a week.
-
Coverage: Ensure thorough coverage on the underside of leaves, where thrips typically reside.
Benefits of Using Vermiwash
-
Eco-Friendly: No chemical residue; safe for pollinators like bees and butterflies.
-
Cost-Effective: Can be produced on-farm using kitchen waste and earthworms.
-
Sustainable: Enhances soil and plant health, reducing long-term dependency on chemicals.
