Use of molybdenum in green germ

Molybdenum is a micronutrient that green gram crops require in very small amounts.
But its very small quantity is also very important for good growth of green gram crop.
Molybdenum plays a very important role in chemical changes in nitrogen in green gram crops.
Growth of green gram crops is not proper, due to deficiency of molybdenum.
Yellowing occurs on the edges of the leaves. Symptoms of molybdenum deficiency are similar to nitrogen deficiency.

Do not take samples from the land under the tree, from the meds or the low places, where there is a pile of manure, or where water gets collected.
For soil testing, take the sample in such a way that it represents the entire field, at least 500 grams of the sample must be taken.
Remove organic materials such as crop residue, dry leaves, stalks and grasses etc. from the top surface of the soil and choose samples from 8-10 different locations according to the area of the field.
Soil sampling should be done from the depth at which the root crop is taken.
Soil samples should be collected in a clean bucket or tagari etc.
Make sure to label the sample precisely.

Aphids are small, soft-bodied small insects that can be yellow, brown, green, or black.
They usually suck the sap from the plant by forming groups on the corners of small leaves and twigs and secrete sticky substance (honeydew), which increases the chances of fungal diseases.
Leaves and twigs may wither or become yellow due to severe infestation.
Spraying of Thiamethoxam 25% WG @ 100 gram/acre or Imidacloprid 17.8 %SL @ 100 ml/acre or Flonicamid 50% WG @ 60 gram/ acre to protect against aphid.
Use Beauveria Bassiana @ 250 gram/acre as biological treatment.

This is a seed borne disease ,and it’s caused by a fungus called ustilago segetum.
The infected seed appears to be healthy.
Symptoms of this disease are visible only when spikes are formed. In infected plants in spikes black powder ( spores) found instead of grains
Which also infects seeds produced in other healthy spikes by being suspended in the air.
Seed treatment is the best way to control this disease.
Apart from this, for the control of this disease use Kasugamycin 5% + Copper oxychloride 45% WP @ 300 gram/acre or Carbendazim 12% + Mancozeb 63% @ 600 gram/acre or Tebuconazole 10% + Sulfur 65% WG @ 500 gram/acre
Spray Pseudomonas fluorescens @ 250 gram/acre as a biological treatment.

In wheat crop rust disease is also known as ‘Gerua’
This disease has three types: yellow rust, black rust, brown rust.
In this disease yellow, black, and brown colored powder gets deposited on the leaves.
As the temperature drops, the infestation of this disease increases.
The accumulation of powder on the leaves deprives the leaves their ability to make food.
Due to which the leaves start drying greatly affecting the production.
For prevention of this disease use 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 use Trichoderma Viride @ 500 gram/acre or Pseudomonas Fluorescens @ 250gram/acre.

It is a common disease in garlic crops caused by Thrips insect, this disease heavily harms garlic in its main stages.
This insect begins by scratching the garlic leaves with its mouth, and after scratching the delicate part of the leaves, it sucks its cell sap . Thus it damages the plant by scratching and lapping.
This causes the leaves to curl. Gradually this problem increases, the leaves begin taking the shape of Jalebi. In this way, the plant dries hence the name Jalebi disease.
Use of the following products is necessary for the prevention of this disease.
Profenophos 50% EC @ 500 ml / acre or Acephate 75% SP @ 300 gram/acre or Lambda cyhalothrin 4.9% CS @ 250 ml/acre or Thiamethoxam 12.6% + Lambda cyhalothrin Spraying @ 9.5% ZC @ 80 ml/acre or Fipronil 40% + Imidacloprid 40% WG @ 40 gram/acre or Fipronil 5% SC @ 400 ml/acre or Acephate 50% + Imidacloprid 1.8% SP @ 400 gram/acre
Use Bavaria Bassiana @ 250 gram/acre as a biological treatment

Most of the farmers have planted watermelon crops in their fields.
Watermelon crop is still in the early stage of germination due to which insect pests in watermelon crop are more visible.
In the early growth phase, leaf miner, sucking pests attack on watermelon crops .
To control, use Thiamethoxam 12.6% + lambda cyhalothrin 9.5% ZC @ 80 ml/acre or Fipronil 40% + Imidacloprid 40% WG @ 40 gram/acre or Abamectin 1.9% EC @ 150 ml/acre.
Use Beauveria Bassiana@ 250 gram/acre as a biological treatment.

Watermelon is being planted on a priority basis in the summer .
But after germination of watermelon crops, problems of yellowing in leaves, rotting of roots, stem rot etc. are seen in watermelon crops.
To prevent this, 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

Pumpkin crops are still planted in most of the field.
Some fruits are appearing, but they are not fully developed, and they are small in size.
This problem is due to the poor activity of honey bees because of weather changes.
As you all know, honey bees naturally support pollination in pumpkin crops.
If there is a decrease in the activity of honey bees, then the growth of fruits of the pumpkin fruit is improper or fruit is not produced.

The main symptom of this disease is onion roots becoming pink.
When the infection is high, the roots become black and dry.
Due to this, the growth of tubers is greatly affected.
It is very important to use the following products to prevent this.
Use Kitazin 48% EC @ 400 ml/acre or Thiophanate Methyl 70% W/W @ 300 gram/ acre.
Use Trichoderma viride @ 500 gram/acre as soil treatment and Pseudomonas fluorescens @ 250 gram/acre as spray as biological treatment.
