CONTROL OF BACTERIAL LEAF SPOT,BLIGHT AND STEM ROT IN BETELVINE

Spray Streptocycline @ 400 ppm + Bordeaux mixture @ 0.25% at the time of first disease symptoms appear. Continue spraying at 20 days intervals.  Always spray the chemical after plucking the leaves.

CONTROL OF BLACK ROT DISEASE IN CABBAGE CROP

Black rot disease in cabbage  can be controlled by dipping the seeds in 100 ppm Streptocycline for 30 minutes. Two sprays with 2 g/lit Copper oxychloride + Streptocycline  100 ppm after planting and head formation is recommended. 

CONTROL OF BACTERIAL LEAF BLIGHT(BLB) DISEASE IN PADDY CROP

Bacterial Leaf Blight(BLB) is considered as a major  threat to rice production because of its wide spread, distribution and its destructiveness under favourable conditions. The disease is caused by Xanthomonas oryzae pv. oryzae is one of the most destructive disease in irrigated and rain fed environment in Asia and cause considerable loss. Thus, a field trial was conducted during Kharif 2016 at AHRS, Bavikere to know the efficacy of different commercially available antibacterial chemicals and bio-agents against the bacterial leaf blight of rice. Results indicated that, streptocycline + copper oxychloride combined treated plots showed the lowest per cent disease incidence of 22.33 per cent. Highest grain yield of 56.49 q/ha was recorded in streptocycline + copper oxychloride, which was significantly superior over all the treatments.

CONTROL OF CITRUS CANKER DISEASE

Citrus Canker(Xanthomonas citri)  is the most serious bacterial disease of sour lime during rainy season. The disease symptoms appear on leaves, branches and fruit stalks. Canker lesions appear as yellowish spots, which gradually enlarge and appear as raised, rough brownish pustules. These pustules are surrounded by a characteristic yellow halo. Canker lesions on the fruits are confined to the rind only and do not penetrate into the flesh of the fruit. The market value of the canker-affected fruits is very much reduced. Control : Pruning and burning all the canker-infected twigs before monsoon and disinfecting the cuts with Bordeaux paint can prevent the further spread of disease. Three sprays of Streptocycline 100 ppm (10 g of Streptocycline + 5 g Copper Sulphate in 100 litres water) or Blitox (0.3%) or neem cake suspension (1 kg in 20 litres water) during February, October and December can control the disease.
