Current occurrence and Control of Diseases and pests in Rice Seedling Field

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, Aphids, thrips and blight mainly occur in rice seedling stage, which endanger the growth of rice seedlings. Rice thrips and nymphs are often harmful to the ears, tongues and heart leaves of rice thrips, and yellow and white spots appear in the damaged parts, followed by flower and white spots on the leaves, and the damaged seedlings return slowly to green and shrink, as if they were "sitting". Rhizoctonia solani mostly occurs in wet (semi-arid) seedling fields and dry seedling fields, causing dead seedlings. Due to the unstable temperature in the first and middle of April, it is easy to cause aphids, thrips and blight, affecting the whole seedling, full seedling and strong seedling. Ask the agricultural technology centers of township offices to strengthen water.

Due to the unstable temperature in the first and middle of April, it is easy to cause aphids, thrips and blight, affecting the whole seedling, full seedling and strong seedling. The agricultural technology centers of township offices are requested to strengthen the investigation of rice diseases and insect pests at seedling stage so as to control diseases and insect pests such as blight.

Prevention and control methods and agents:

1. 50% Kuling is sprayed with 50 kg water per mu to control blight.

2. Spray 50 kg of water with 10% imidacloprid 1-1.5 per mu to control aphids and thrips.
