Plants in pest control
- Spores-based bio-products.
The market-ready products are "Green Muscle" (GTZ, 2001) and "Green Guard" (CSIRO, 2001). These are Metarhizium anisopliae (Maa) based. Maa is an insect-pathogen fungus found to be effective against locusts. These commercial bio-products are locusts host specific. FAO expert commission attested to the efficacy and absolute harmlessness in environmental terms of both products (GTZ, 2001; CSIRO, 2001). Ask for assistance from your local agriculturist office for more information.
- Spores of the protozoan, Nosema locustae (
University of Nebraska, 2000). These are commercially available as bran baits for grasshoppers.
- During locust infestation, farmers should act swiftly. Collect and kill the pests, (using sweep nets, broom or twigs) because they can damage plants quickly (Reissig; Heinrichs; Litsinger; Moody; Fiedler; Mew; Barrion, 1986: pp. 110-112).
- Use fine mesh nylon nets as row covers to protect valuable plants and seedlings.
- Salty rice bran bait.
Moisten rice bran with salty water. Locusts feed on salty rice bran (Reissig; Heinrichs; Litsinger; Moody; Fiedler; Mew; Barrion, 1986: p. 117).
