What is yellow vein mosaic of green gram and how to control it

Yellow vein mosaic is a major viral disease caused in green gram.
It spreads due to white fly and causes 25-30% of damage.
The symptoms of this disease can be seen in all the stages of the plant.
In this disease the veins of the leaves become yellow and a mesh-like structure is formed on the leaves.
To prevent this,use Acetamiprid 20% SP @ 100 gram/acre or Diafenthiuron 50 % WP @ 250 gram/acre or Pyriproxifan 10% + Bifenthrin 10% EC @ 250 ml/acre
Use Beauveria Bassiana @ 250gram/acre as a biological treatment.

Elements which are very essential for good germination of Green Gram should be given in the form of soil treatment at the time of sowing.
DAP @ 40 kg/acre + MOP @ 20 kg/acre + zinc sulphate @ 5 kg and mix in soil and broadcast the field before sowing.
Also use ‘Moong Samriddhi Kit’ which will become the safety shield for your crop.
This kit will provide everything which is needed for the green gram crop. There are many products included in this kit,
Such as consortia of PK bacteria, Rhizobium bacteria, Trichoderma viride, humic acid, seaweed, amino acids and mycorrhiza

The early symptoms appear on the lower leaves which turns the color of the leaves brown.
Due to this disease, the leaf takes up a cylindrical form and falls.
For the prevention of this disease, Thiophanate methyl 70% W / W @ 500 gram/ acre or chlorothalonil 75% WP @ 400 gram/acre.
Use pseudomonas fluorescens @ 250 gram/acre as a biological treatment

In okra crop, managing the crop within 15 days of sowing is very essential for good growth.

Crop management can be done in two ways

Crop management with soil application: Urea @ 50 kg + Sulfur @ 5 kg + zinc sulphate @ 5 kg + micronutrient @ 10 kg.

Spray management: Thiamethoxam 25% WG @ 100 gram/acre + Thiophenate methyl 70% W /W @ 500 gram/acre for pest management and disease management

In okra crops, it is very important to manage weed in 3 -5 days after sowing.
In this stage, the growth and development of okra is greatly affected when weeds sprout.
For this, spray Pendimethalin 38.7% CS @ 700 ml/acre for weed control.
Use only the appropriate amount of weedicide.

Thrips are sucking pests that sucks cell sap with their pointed mouthpart.
The leaves of the affected plant appear dry and withered, or the leaves become discolored and curl upwards.
For the control of thrips it is necessary to switch chemicals after every use.
Management: – For prevention of thrips use Fipronil 5% SC @ 400 ml/acre or Lambda Cyhalothrin 4.9% CS @ 200 ml/acre or Fipronil 40% +Imidacloprid 40% WG @ 40 gram/acre or Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC@ 80 ml / acre or Spinosid 45% SC @ 75 ml/acre.
Biological treatment: – As a biological treatment, spray Beauveria Bassiana @ 250gram/acre.

Zinc stimulates enzyme activity in plants and plays an important role in the production of hormones.
Zinc is helpful in protein synthesis and the lack of zinc in the pulse crop decreases the rate of protein accumulation, leading to a decligreatlyod formation.
It acts as a catalyst in chlorophyll production, thus helping plants in food production.
Zinc promotes the use of phosphorus and nitrogen by plants.
Due to its deficiency, the size of the leaves remains small, it curls and yellow stripes appear between its veins.

It is very important to have good and healthy seeds for good crop production.
The farmer collects some of the new seeds from the latest produce for sowing next time.
It is very important to properly grade the seeds before keeping these seeds in the storage.
To do this, the variety of seeds that have been selected to be cultivated should be sown in a good field, apart from the rest of the crop.
Sow the seeds only after soil treatment and seed treatment.
To keep the crop free from pests and diseases throughout the crop cycle, spray chemicals from time to time.
This way farmers can produce disease free seeds.

Particles of mycorrhiza fungi attach microscopically with the roots of watermelon plants, and provide the nutrients required for root growth and development.
Especially elements like phosphorus, potash, etc. help increase the growth of watermelon crops.
Mycorrhizal fungus helps the watermelon plant to absorb more nutrients and water from the soil.
Mycorrhiza fungi increase the tolerance of the plant to withstand various types of environmental stresses.
In addition, mycorrhiza fungi play an important role in the absorption of all types of essential nutrients in soil.

Watermelon is a shallow rooted crop, hence intercultural activities can be done very comfortably.
Often,weeding is done between the rows of crops. Weeds should not grow too much in the field, in the event of large weeds growing in the field, they should be uprooted by hand and separated.
Spray chemical weedicide like Pendimethalin 30% CS @ 700 ml/acre during 1 to 3 days before germination of weeds .
For control of narrow leafed weeds use Quizalofop ethyl 5% EC @ 400 ml / acre at 2-4 leaf stage with or Propaquizafop 10% EC @ 400 ml/acre at 10 to 25 days of crop stage.
