Deadly viral infections in chilli like Leaf curl virus [Gemini virus], mosaic virus and TOSPO [tomato spotted wilt virus] are spread from plant to plant is at young growing stages before the age of 25 days and this particular stage is most vulnerable stage for spreading and carrying the viral infections which may express at later stages .

Viral infections in chilli crop

So, raise the saplings under controlled conditions where the germinated saplings or seedlings will be protected from sucking pest vectors like whiteflies, thrips, aphids and other plant hoppers providing minimal chances of viral infections at later stages.

Tomato crop is prone to viral infections especially in summer days. Plants show symptoms of spots on plants, like fungal infections, Flowers bunches burn and yield gets reduced. Plants end up growing. Fruits show the symptoms of reduced size, dis-colouring and loose the glossyness of fruits.

Viral infections are said to spread by sucking pests like Thrips and whiteflies.

Ammoniacal nitrogen supplement to the tomato crop promotes viral infections so reduce the application ammoniacal nitrogen containing nitrogen sources.

Following sprays may be administered to prevent and manage the TOSPOW and other viral infections in tomato crop.

Avoid fruit cracking on pomegranates

Fruit cracking is common in summer seasons due to irregular supply of irrigation during fruit stage leads the fruits to crack. So plan the irrigation water requirements and provide timely irrigation to the plants to the fruiting plants.

Pomegranate fruit cracking

Calcium deficiency sometimes lead to the cracking of fruits as the skin may not be strong enough to hold the developing fruits. The calcium spray on the plants and fruit may avoid the cracking of fruits. Boron inclusion will help fruit put some weight and taste better.

Amruth calcium nitrate 5 gm/L + Boron 20 -1 gm/L + Spraywell 1 mL/L

Go Mulching for high yields in vegetable crops

Applying mulch sheet to control the sucking pests, weeds and reduce the water requirements.

Mulch sheet at early stage for soil for pest control and moisture control

During early stages of plant growth reflecting nature of mulch sheet disturbs the sucking pests to find the perfect host plants to attack upon.

Sucking pest which infests the vegetable crops which can be controlled by applying mulch sheet at early crop stages

Reflective mulch works better for Tomato, Capsicum and chilli crops.Mulching also helps in reduced moisture evaporation for plant root zones, avoid growing of weeds at the root zones.

Grow Marigold crop as trap crop to manage insect pests in Organic vegetable cultivation

Trap crops are the crops grown in between the target main crop to attract insects or pathogens protecting the main crop insect and disease attack. Pest reduction in main field may be due to the prevention of pest attack on target crop by attracting them with special characters like attractive flowers and smells. These trap crops may also attract natural enemies of insect pests and keep check on the pests on the target crops.

Intercrop in Tomato crop

Marigold crop may be grown as insect trap crop along with main crop to attract insects like Helicoverpa armigera fruit borers in tomato and other vegetable crops without damaging much the main crop.

Fruit borer HELICOVERPA ARMIGERA on tomato and chilli crop

Marigolds may be grown one row for every 7 rows of main crop.

Manage Whiteflies and Yellow Vein Mosaic virus on Bhendi [Okra or Bhindi] Crop

Yellow vein mosaic of bhindi or vein clearing of bhindi is the most devastating disease in all the bhindi growing regions of India. Up to 80% of crop loss is expected if the crop is infected at early stages.

Whiteflies' spread Yellow Vein Mosaic Viral infection on Bhendi

Begamo virus is the causal organism and transmitted by white fly Bemisia tabaci. The occurrence and infestation of white flies are more severe in summer months and Yellow vein mosaic viral infections is also high.

Ammoniacal nitrogen has also positive advantage towards increase of viral infections so restrict use of ammoniacal nitrogen application instead go for Nitrate form of Nitrogen.
Removing and destroying disease affected plants from crop fields to avoid secondary spread.

Organic management [Mechanical method] of brinjal shoot and fruit borer

Brinjal Fruit and Shoot Borer (Leucinodes orbonalis) is very important pest of brinjal crop.

Shoot and fruit borer infestation on Brinjal crop

Water-trough pheromone traps may be used to mass trap male adult of Brinjal shoot and fruit borer moths with Leucinodes lures.

The pheromones traps trap the adult male moths (and not female ones) and kills in the fields which will be flying in the brinjal fields in search of female moths for mating.

organic- Mechanical method in controlling Brinjal shoot and fruit borer1.jpg

This avoids the mating phenomenon with female moths and reduces the fertilization of the eggs laid by female moths consequently reduce the carryover of pest.

10-15 traps per acre may be installed for efficient management of brinjal fruit and shoot borer.

Manage White flies on Vegetable and Flower crops

White flies attack many plant species in the open fields and as well as in the greenhouses. White flies suck sap from the plants, causing yellow mottling on the surface of the leaves, wilting and stunting. They also help in transmission of viruses and producing honeydew, which attract black fungi of sooty molds.

Damage of Plants by White flies

Reducing the quantity of Nitrogen, as high nitrogen favours the succulent growth which may increase whitefly infestations.
Phosphorus and Magnesium deficiencies’ symptoms in plants are believed to contribute more to white fly infestations among the crops.

Sprays to control Whiteflies

Econeem plus 1 % - 1 mL/L + Odis 2 gm/L and after 5-6 days

Spray for White fly control

Tafgor 5 mL/L + Econeem plus 1 % - 1 mL/L + Caldan SP 1.5 gm/L
