Crop weather situation
Nutrients should be supplied through foliar application to rainfed fruits vegetables and fruits for better nutrient uptake. Farmers may take up spray of Banana special in Banana and vegetable special in all vegetables. Farm yard manure or compost may be mixed with Arka Microbial Consortium.
Incidence of insect pests
Under the prevailing weather situation, following pests are expected under Bengaluru conditions on different horticultural crops. Various management options for their management are mentioned below.
Thrips on Grapes
- Thrips, Scirtothrips dorsalis is expected to occur on leaves of newly pruned Bangalore Blue. Spray fipronil 5 SC @ 1.5ml/L or Metarhizium formulations.
Caterpillar pests on tomato
- With the prevailing weather, incidence of various caterpillar pests like tobacco caterpillar and tomato fruit borer may increase on tomato. For the management of both these caterpillar pests, spray indoxacarb 14.5 SC @ 0.75ml/l.
Tomato moth
- Install tuta pheromone traps for monitoring of the adults @ 4-6 traps/acre
- Spray indoxacarb 14.5SC @ 0.75 ml/litre or spinosad 45SC @ 0.3ml/l
Aphids on brinjal & bhendi
- Incidence of aphids is increasing on brinjal and bhendi. If the crop is at preflowering stage, spray imidacloprid @ 0.3 ml/l. After the fruit set, spray neem or pongamia soaps @ 10g/l or pulverized neem seed powder extract (NSPE) 4%, by covering the lower surface of the leaves thoroughly
Mites on tomato
- During the period, incidence of mites is observed in different tomato fields. Spray *spiromesifen 22.9SC @ 0.5 ml/l for their management
Aphids on rose and beans
- Aphid infestation may increase on rose and other bean vegetables. Spray imidacloprid 200SL @ 0.5 ml/l for their management
Helicoverpa on china aster
- Incidence of Helicoverpa may increase on china asters. Spray indoxacarb 14.5 EC @ 0.75 ml/l for its management.

- Disease scenario
Disease scenario in relation to the weather data during first fortnight of November, 2024.
Vegetable crops:
Solanaceous and cucurbits vegetables
- Powdery mildew requires attention. At this point of time application of wettable sulphur (0.2%) along with sticker @ 0.5 ml/L is recommended.
- Leafspots and Anthracnose spots may increase on foliage. Application of Chlorothalonil (0.2%) along with sticker (@ 0.5 ml / L) is recommended for the disease management
Fruit Crops
Mango
- Powdery mildew requires attention. At this point of time application of wettable sulphur (0.2%) along with sticker @ 0.5 ml/L is recommended.Anthracnose spots may increase on foliage. Application of Chlorothalonil (0.2%) or Thiophanate methyl (0.2%) or Carbendazim (0.1%) along with sticker (@ 0.5 ml / L) is recommended for the disease management
Grape
- Downy mildew and anthracnose need to be monitored. For the management of downy mildew application of Metalyxl + Mancozeb (0.2%)/ Al Fosetyl (0.2%)/ Dimethomorph (0.8%) + Mancozeb (0.2%) and for anthracnose spraying with Propineb (0.2%)/ Chlorothalonil (0.2%)/ Carbendazim (0.1%)/ Thiophanate methyl (0.1%) are effective.
Banana
- Sigatoka leaf spot (Mycospheralla sp.), crown rot (Fusarium moniliforme & Botryodiplodia theobromae) and anthracnose (Colletotrichum musae) of fruits require proper attention. Sigatoka could be managed by spraying propiconazole at 1 ml per litre.
Papaya
- Infection of Black spot (Asperisporium caricae) is increasing.Application of Chlorothalonil (0.2%) Carbendazim (0.1%)/ Thiophanate methyl (0.1%)/ Hexaconazole (0.1%) along with the sticker @ 0.5ml/l with good coverage of the lower surface of the foliage is recommended
Ornamental crops
Chrysnthemum
- This is the time for rust and spraying Chlorothalonil (2g/l) as contact fungicide will reduce the incidence. In severe cases propiconazole (1.5 ml/l) will help in preventing the further spread of the disease
Rose
- Now the powdery mildew incidence will increase. Spray of azoxystrobin at 0.05% or trifloxystrobin + tebuconazole at 0.1% will reduce the powdery mildew spread
