Control of thrips in onion field
Thrips are one of the most important pests of green onions. Adult thrips and nymphs use file-sucking mouthparts to harm the heart leaves, tender leaves and buds of the plant, suck up juice, and form many fine silver-white stripes on the leaves. The leaf tip is dry, and in serious cases, the leaves are inedible, which has a great impact on the yield and quality of green onions. The thrips that damage green onions are mainly onion thrips, tobacco thrips and rice tube thrips, which are often mixed, which are in the peak period from May to September. The thrips are small, light yellow to dark brown, and the insect is one year old.
