Manage TOSPO virus in tomato crop

07/08/2021 Saturday August 7th, 2021

TOSPO virus is a viral disease of the tomato crop mainly due to poor nutritional management and is spread by thrips. Poor nutrient management refers to the use of ammonium fertilizers, excessive use of amino acids, use of poultry manure etc.
Its symptoms are curling of leaves, black spots on leaves and yellowish-green spots on fruits. It can be managed by proper application of micronutrients and control of carriers that spread the TOSPOvirus. To overcome the deficiency of nutrients, micronutrients can be sprayed, as well as to control thrips in tomato crop, spray the following insecticides-
Spray Fipronil 5% SC 2 gm or Cyantraniliprole 10.26 % Od 240 ml or Spinosad 45% SC 75 ml per acre.

Herbicides to control weeds in onion crop

06/08/2021 Friday August 6th, 2021

Onion is an important cash crop that is grown in Kharif as well as in rabi season. The Kharif and rabi onion cultivation is predominantly grown under light to medium soils that face weed competition from weeds like Dactyloctenium aegyptium, Eleusine indica, Cynodon dactylon, Cyperus rotundus, and Parthenium hysterophorus.
Application of Pendimethalin 38.7% CS @ 700 ml/acre at 3 days after transplanting are recommended for effective weed control in onion along with one weeding by hand at 25-30 days after transplanting in Kharif crop.
The combined application of Oxyfluorfen 23.5 % EC @ 100 ml/l + Quizalofop Ethyl 5 % EC @ 300 ml per acre at 20-25 days after transplanting and having at 30-35 days after transplanting good control of weed and higher bulb yield.

Weed outbreak will increase in Paddy Crop, Manage it soon

05/08/2021 Thursday August 5th, 2021

Weed control is one of the most difficult and laborious cultural activities in paddy cultivation. If not controlled properly, crop loss can be up to 50%.

The following herbicides can help you, control weeds in the paddy crop:

Why do onion plants show tip burn problems?

05/08/2021 Thursday August 5th, 2021

The problem of tip burn in onion crops mainly appears at the time of crop development when the crop is close to the mature stage then the process of tip burning can be natural, but in young plants, tip burn can happen due to many reasons. Possible causes include a lack of important nutrients in the soil, fungal infections, or sucking insects such as thrips, etc.
Heavy wind, excessive sunlight, excess salt in the soil and other environmental factors can cause onion tips to burn. Given all the possible causes of leaves with brown, dry tips, it can be hard to pinpoint what is affecting the plant, remember if you have taken care of all of the above problems, It could be fungal related.
To remedy the problem of tip burn, keep all the above things in mind, spray 200 ml per acre of neem oil 10000 ppm to protect against sucking insect leaf minors, thrips, etc.
Spray Fipronil 5% SC 400 ml + Tebuconazole 10% + Sulphur(s) 65% WG 500 gm + Triacontanol 0.1% EC 100 ml per acre.

Integrated pest management of Diamondback Moth in cole crops

03/08/2021 Wednesday August 4th, 2021

The diamondback moth, Plutella xylostella is one of the most destructive pests of cole crops like Cauliflower, cabbage and broccoli. The caterpillar of this insect eats away the green matter of the leaves and only white membrane remains at the eaten site which later turns into pores and gradually the damage starts appearing on the whole plant. This pest can reduce the marketable yield by 50-80%. Its outbreak is more visible in the months of September to October and March to April.

Management:

Grow two rows of mustard after every 25 rows of cabbage/ cauliflower as a trap crop at the time of planting. One row of mustard is sown 15 days before cabbage planting and the second row 25 days after planting of cabbage. The first and last rows of plots are also mustard.
Installation of light traps for adult DBM @ 3-4 traps / acre.
Spraying with Bacillus thuringiensis 100 gm or Spinosad 45 % SC 75 ml per acre and repeating it at 10- 15 days intervals.
Chemical control- Spray at Emamectin Benzoate 5% SG 100 gm or Chlorantraniliprole 18.5 % SC 60 ml per acre.

How to control Aphid in Maize Crop

30/07/2021 Thursday July 29th, 2021

Nymphs and adults are soft pear-shaped to black in colour.
In groups of young and adults appear to the lower surface of the leaves, which suck the cell sap of the leaves.
The affected part turns yellow and shrinks. In case of severe infestation, the leaves dry up and gradually the whole plant dries up.
Fruit size and quality are reduced.
Honeydew is secreted on the surface of leaves by aphids, which leads to the development of fungus. The process of photosynthesis of the plant is affected, ultimately the growth of the plant stops.

Symptoms and control of anthracnose disease in soybean

29/07/2021 Wednesday July 28th, 2021

Irregularly shaped spots appear on the pods of infected plants. This disease is usually seen on the stem of soybean, at the time of maturity. Anthracnose causes the death of soybean tissue. The disease usually infects the developing stem and leaves. Its symptoms can be seen as various coloured spots or lesions (blight) on leaves, stems, fruits, or flowers, and some infections also occur in the form of cankers on twigs and branches. The severity of infection depends on both the causative agent and the species infected.
The spread of disease should be prevented by keeping the fields clean and adopting proper crop rotation.
Treat the seeds with Carbendazim 12% + Mancozeb 63%WP @ 2.5 gm/kg of seed.
