What is the reason of yellowing of garlic and onion leaves

Constantly changing weather is causing the garlic and onion crop to face a lot of problems.
The problem of yellowing is quite visible in the garlic and onion crop due to which there is a huge impact on their growth and development.
The yellowness of garlic and onion can also be caused by fungal and insect borne and nutritional problems.
If it is causes by fungus, use Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 gram/acre or Thiophanate Methyl 70% WP @ 300 gram/acre
If it is because of nutritional problem, use Seaweed@ 400 ml/acre or Humic acid@ 100 gram/acre
If it is due to insect, use Profenofos 40 % + Cypermethrin 4% EC@ 400 ml/acre or Fipronil 40 % + Imidacloprid 40 % WG@ 80 gram/acre.

The watermelon crop requires 16 nutrients mainly. In which boron is the most essential nutrient in a group of micronutrients
Boron does not allow the roots of watermelon plants to deform and maintains the growth of the roots continuously.
Deficiency of boron distorts the shape of leaves, and the formation of fruits is reduced.
The growth of leaf and stem is very less and the fruit of watermelon starts bursting.
Boron nutrient supply can be done by spraying, through drip or by adding pre-sowing soil treatment.
So use boron after the soil testing . Keep in mind that excess of boron also has toxic effects on the plant.

Cow urine is like a nectar for crops and soil.
There is no smell of any kind in insecticide that is prepared from urine.
Pests do not sit on crops or fruits after spraying.
Nitrogen content is found in urine, due to which urine increases the amount of nitrogen in plant root,
It helps in the growth of roots.
Its use increases the amount of micro beneficial bacteria in land . The natural form of the land remains.

Organic farming is very beneficial for farmers.
This increases the fertile capacity of the land.
Irrigation intervals increase because organic manure maintains moisture in soil for a long time.
Reducing dependence on chemical fertilizer reduces costs.
Increase in productivity of crops.
The market price of the products obtained from organic farming is higher, which increases the income of farmers.

In mustard crops there is a heavy attack of sawfly.
It is black in color, which damages the leaves quickly, it consumes the leaves, making holes on the sides of the leaves.
This skeletonizes mustard leaves .
To prevent this, spray Profenofos 50% EC @ 500 ml/acre or Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 80 ml/acre or Imidacloprid 30.5% SC @ 50 ml/acre

In watermelon fruit sometimes deep rotten patches and a wrinkle-like structure is formed.
These are caused usually due to improper intervals of irrigation.
When the soil of the field becomes very dry, it fixes calcium in the soil, prohibiting the plants from absorbing it.
To prevent this, use calcium nitrate @ 10 kg/acre.

Leaf Miner insects are very small. They burrow inside the leaves and make tunnels.
These tunnels look like white stripe ridges on the watermelon leaves.
The adult moth is light yellow in color and the baby moth is very small and footless . This moth makes a tunnel in the leaves and in this tunnel the pupa is formed.
Insect infestation occurs on the leaves. A spiral tunnel is formed on the affected leaf. Photosynthesis of plants is affected . Hence, the leaves fall.
For the control of this insects use , Abamectin 1.9% EC @ 150 ml/acre or Chlorantraniliprole 8.8 + Thiamethoxam 17.5% SC @ 200 ml/acre or Cyantraniliprole 10.26% OD @ 300 ml/acre

By managing fertilizer before sowing, the soil gets replenished of any nutrients the soil is deficient of.
Thus by managing fertilizer, the okra seeds are easily supplied with essential nutrients at the time of germination.
Use DAP@75 kg/acre + potash @ 30 kg/acre at the time of sowing.
Okra crops need to be protected from many different types of diseases along with manure.
For this, soil treatment should be done before sowing or at the time of sowing use soil samridhi kit. This kit contains all the essential products which are very beneficial for okra crops.

VigorMaxx Gel gives tremendous nutrition to your crop.
It helps in increasing the yield of crops and keeps them stress free.
It also absorbs all the micronutrients present in the soil and makes it available to the plants for their healthy growth.
It enhances the density of soil.
It improves the air and water holding capacity of soil.
It promotes healthy growth of the crop by improving physiological processes such as photosynthesis, cell enlargement, cell division and energy transfer.

In onion crops, in 40-50 days the crop has to be protected from insects and fungal diseases, as well as nutritional requirements have to be fulfilled.
Therefore in this stage of onion crop it is necessary to manage the crop in three different forms.
To protect against fungal diseases: – Use Tebuconazole 10% + Sulfur 65% WG @ 500 gram/acre Metalaxyl 4% + Mancozeb 64% WP @ 600 gram/acre
Use Pseudomonas fluorescens @ 250 gram/acre as a biological treatment
To protect against insects : – Spray of Fipronil 40% + Imidacloprid 40% WG @ 40 gram/acre or Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 80 ml/acre
Use Beauveria Bassiana @ 250 gram/acre as a biological treatment.
Nutrition Management: – In this stage of onion nutrition management is done as soil treatment, for this use calcium nitrate @ 10 kg/acre + potash @ 20 kg/acre.
While spraying onion crops, one thing should be kept in mind that for every product to be absorbed or used by the leaves well, use 5 ml / pump sticker per pump at every spray time.
