How to manage Rust disease in soybean crop

15/08/2021 Sunday August 15th, 2021

In the soybean crop, rust disease is known as gerua disease. The probability of an outbreak of this disease increases with frequent rainfall and low temperature (22 to 27 °C) and high humidity (relative humidity 80-90%). The intensity of the disease increases when there is fog during the night or early morning. As the temperature drops, so does the outbreak of this disease.
Due to the accumulation of yellow powder on the leaves, the process of making food of the leaves is greatly affected, due to which later the leaves start drying and the production is greatly affected.
To control this disease, spray Hexaconazole 5% SC @ 400 ml/acre or Propiconazole 25% EC @ 200 ml/acre or Tebuconazole 25.9% EC @ 200 ml/acre.
As a biological treatment, spray Trichoderma viride @ 500 g/acre or Pseudomonas fluorescens @ 250 g/acre.
Disease resistant varieties Indira Soya-9, DSB 23-2 DSB Sow 21 and Phule Kalyani etc. Uproot the diseased plant and keep it in polythene, bury it in a pit outside the field or destroy it.

Symptoms and Measures of Anthracnose disease in soybean

10/08/2021 Tuesday August 10th, 2021

Anthracnose is an important disease of the soybean crop, causing yield loss of up to 16-100%. This disease affects all stages of crop development. Symptoms can be seen on leaves, fruits, pods and even stems. Irregularly shaped spots, dark sunken lesions or reddish-brown spots appear on the plant. In the early stages of the infection, there are no seeds formed in the pods. The favourable temperature is 28-32 ºC. The pathogen infects the host at a minimum temperature of 22-25ºC.
To prevent this, spray Tebuconazole 10% + Sulfur 65%WG @ 500 gm/acre and Carbendazim 12% + Mancozeb 63% WP @ 300 gm/acre and Thiophanate Methyl 70% WP @ 300 gm/acre.
For biological treatment, spray of Trichoderma viride @ 500 gm/acre or Pseudomonas fluorescens @ 250 gm/acre can be done.

How to control downy mildew disease in cucurbits

09/08/2021 Wednesday August 11th, 2021

Downy mildew is a serious and common fungal disease during warm and humid conditions with overcast days. The undersides of leaves are speckled with small, water-soaked spots that become powdery patches of mycelium and spores.
The infections are usually concentrated near the leaf veins. The white patches are from 1–6 cm in diameter, with corresponding yellowish-green spots on the upper leaf surface. As the disease progresses, severely infected leaves become necrotic and appear scorched. They curl and fall from plants prematurely. Mildew on immature fruit begins as circular patches of white mycelium and spores that can coalesce and cover the entire fruit. As the fruit ripens, the fungus may disappear, leaving behind grey scars. The scars restrict the growth of the underlying tissue, resulting in deformed fruit. The deformed fruit is edible but has little or no value in the market.
Chemical control of downy mildew disease on crops-
Chlorothalonil 75 % WP 400 gm or Metalaxyl 8%+Mancozeb 64% 500 gm per acre spray can control the downy mildew disease.
For biological control Trichoderma viride 0.5 kg per acre can be used.

08/08/2021 Sunday August 8th, 2021

Chilli is one of the major horticulture crops, it can be cultivated by both drip irrigation systems or flood irrigation.
Fertilizer management for flood irrigation: Use 25 kg urea + 25 kg DAP + 25 kg muriate of potash + 12 kg magnesium sulphate / acre + phosphorus and potash bacteria 2 kg per acre on 40-60 days of transplanting.

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.

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.

Due to the accumulation of yellow powder on the leaves, the process of making food of the leaves is greatly affected, due to which later the leaves start drying and the production is greatly affected.
