ShareControl of Neck Blast in Paddy
Neck Blast of Paddy
- Rice blast is one of the most destructive diseases of rice. Because neck and node blast affects the panicle directly, yield losses in affected plants are very high.
- Node infection occurs in a banded pattern.
- Lesions on the node are blackish to grayish brown.
- Infected nodes can cause the culm or the part of the plant that holds the panicle to break.
- Lesions on the neck are grayish brown and can cause girdling, making the neck and the panicle fall over.
- If the infection of the neck occurs before the milky stage, no grain is formed, but if infection occurs later, poor quality grains are formed.
- Neck and node blast can also cause whiteheads or white panicles, similar to stem borer infection.
Control of late blight of tomato
- Destroy all tomato debris after harvest.
- avoid water logging conditions on the farm.
- Spare any one fungicide for disease control.
- Metalaxyl 8%+Mancozeb 64% @ 500 gm/acre.
- Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 gm/acre.
- Pyraclostrobin 5% + Metiram 55% @ 600 gm /acre.
- Dimethomorph 50% WP @ 400 gm/acre.

ShareWeed Control in Tomato Crop
Weed Control in Tomato Crop:-
- About 2-3 hoeing up are essential at the initial stage of plant growth.
- Application of pre-emergence weedicide of Pendimethalin 30% SC @ 700 ml/Acre with one hand weeding 45 days after transplanting is more effective for weed control.
- Application of post-emergence weedicide of Metribuzin 70% WP @ 300 Gm/Acre 15 days after transplanting.
- Application of mulches like straw, saw dust and black polythene are used in controlling weeds, moisture conservation for better quality of yield.
