A new pest-control approach that eliminates the need for chemical sprays is showing real promise for vegetable farmers in Antigua and Barbuda, following a successful field demonstration under an agricultural cooperation programme with the People’s Republic of China.

The trial, conducted with the Ministry of Agriculture through its Crop Research & Development Division, tested the use of fine-mesh insect-proof nets to protect crops without applying any pesticides.

Known as Light and Simplified Green Prevention and Control Technology for Plant Pests, the method relies on physical prevention. Crops are covered with breathable mesh that allows sunlight, air, and rain through, while blocking insects such as aphids, thrips, flea beetles, and diamondback moths.

“If pests can’t reach the plants, there’s no need to spray chemicals,” explained Lu Jiaju, the project’s lead technical instructor.

Chinese cabbage was used in the pilot. Seeds planted under the netting grew evenly and remained completely pest-free through harvest in early January. A nearby plot grown without nets and without pesticides suffered heavy insect damage and near total crop loss.

Agricultural officers observing the harvest described the contrast as dramatic, highlighting the technology’s potential to cut losses and reduce farmers’ costs.

Officials say the method also improves food quality. Crops grown without insect stress or chemical exposure tend to have better taste, appearance, and shelf life—qualities increasingly demanded by consumers.

The Ministry plans to test the netting system on other crops, including tomatoes, cucumbers, eggplant, and watermelon, with expanded demonstrations planned at the Bethesda agricultural base. Farmer training sessions are also expected.
