Paddy hispa (Dicladispa armigera) is a beetle pest of rice where both adults and grubs scrape the leaf surface, leaving characteristic white streaks that reduce photosynthetic area and yield. Because adults are mobile and grubs feed within leaf tissue, contact and stomach-action insecticides with broad-spectrum activity are the mainstay of control. Here are nine proven solutions.
1. Lambda-cyhalothrin 5% EC
Lambda-cyhalothrin is a synthetic pyrethroid with contact and stomach action, offering quick knockdown against a broad range of paddy pests including leaf folder, stem borer, and hispa-adjacent sucking pests. It's one of the most widely used pyrethroids for rice foliar protection.

2. Chlorpyrifos 20% EC
Chlorpyrifos is a broad-spectrum organophosphate acting through contact, stomach, and vapour action. It's specifically registered for hispa and leaf folder in paddy, with good persistence for extended pest control.

3. Quinalphos 25% EC
Quinalphos is an organophosphate insecticide and acaricide with contact and stomach action, specifically registered for hispa/blue beetle control in paddy along with brown plant hopper and leaf folder.

4. Emamectin benzoate 1.9% EC
Emamectin benzoate is a stomach-action insecticide derived from the avermectin family. Larvae stop feeding shortly after ingestion. It's registered for leaf folder and hispa together in paddy.
Product Recommendations
5. Carbofuran 3% CG
Carbofuran is a systemic carbamate insecticide formulated as controlled-release granules, applied to the soil where it's taken up by the roots. It's specifically registered for stem borer, gall midge, green leaf hopper, and hispa together in paddy.
Product Recommendations
6. Flubendiamide 8.33% + Deltamethrin 5.56% SC
This combination pairs a diamide (Flubendiamide) acting on ryanodine receptors with a pyrethroid (Deltamethrin) acting on sodium channels, giving two distinct modes of action for resistance management. It's registered for leaf folder and hispa together in paddy.
Product Recommendations
7. Malathion 50% EC
Malathion is a broad-spectrum organophosphate insecticide with a long history of use, acting via contact and stomach action. It's specifically registered for rice hispa control in paddy.
Product Recommendations
8. Lambda-cyhalothrin 2.50% EC
This is a lower-concentration formulation of Lambda-cyhalothrin, still offering the same contact and stomach mode of action. It's specifically registered for leaf folder, stem borer, green leafhopper, gall midge, hispa, and thrips together in paddy.
