4. Rice stem borar (Sciropophaga Incertulas)
5. Leaf folder (Cnaphalocrocis medinalis)
6. Rice green leaf hopper (Nephotettix cincticeps)
7. Grasshopper (Caelifera).
4. Rice stem borar
Stem borers can destroy rice at any stage of the plant from seedling to maturity. They feed upon tillers and causes deadhearts .
Management
- Use resistant varieties ·
- Raise level of irrigation water periodically.
- destroy egg masses ·
5. Leaf folder
Leaf folders are caterpillars of a moth. ... The feeding creates a see-through whitish area on the leaf. The caterpillars are yellow to green. Heavily infested fields appear scorched and have many folded leaves.
Management
- Practice synchronized crop.
- Apply nitrogen as needed. Application of nitrogenous fertilizer is better in split dose.
- Control weeds in the field.
- Perform crop rotation with a non-rice crop during the dry season to decrease alternate hosts for diseases.
- Intercrop upland rice with soybean to reduce the incidence of leafhoppers on rice.
6. Rice green leaf hopper
Green leaf hoppers cause direct damage to the rice plant by feeding on rice, sucking plant sap, and plugging the vascular bundles.
Management
- Use GLH-resistant and tungro-resistant varieties.
- Practice synchronized crop.
- Apply nitrogen as needed. Application of nitrogenous fertilizer is better in split dose.
- Control weeds in the field.
- Perform crop rotation with a non-rice crop during the dry season to decrease alternate hosts for diseases.
- Intercrop upland rice with soybean to reduce the incidence of leafhoppers on rice.
7. Grasshopper
Grasshopper are green or brown in colour. It feed on grass or crops. It's has chewing type of mouth. It can affect paddy fields by cutting the leaf of paddy plant in plant growth stage.
Management
- Spread EcoBran Bait or apply botanical insecticides, such as organic pyrethrins, to areas where you are experiencing heavy grasshopper damage and require a quick-kill.
- Azadirachtin insecticidal ingredient found in neem oil. This concentrated spray is approved for organic use and offers multiple modes of action, making it virtually impossible for pest resistance to develop. Best of all, it’s non-toxic to honey bees and many other beneficial insects.
- Roto-till or cultivate crops in the spring to destroy overwintering eggs.
- For long-term grasshopper protection, apply organic Semaspore Bait (Nosema locustae) to hatching beds – field margins and other undisturbed grassy areas – when grasshoppers are young. Heavy infestations may require multiple applications.
