How to control Blight in Summer moong crop

Blight: In this disease, dark brown spots are seen on the leaves, spots on the stems are deformed, long, suppressed and purple-black in color. They later merge and surround the entire trunk. Irregular red or brown spots appear on the beans, in the acute stage of the disease, the stem starts to weaken.
Chemical treatment: Mancozeb 75% WP @ 600 gram/acre or Carbendazim 12% + Mancozeb 63% @ 300 gram/acre or Thiophanate Methyl 70% W / W @ 300 gram/acre or chlorothalonil 75% WP @ 400 gram/acre .
Biological management: As a biological treatment, spray Trichoderma viride @ 500 g / acre or Pseudomonas fluorescens @ 250 gram/acre.

In 25-30 days of green gram crop, problems like pest infestation, fungal disease attacks, and stunted growth and development occur.
To overcome these problems, it is very important to do crop management in 25-30 days of green gram crop.
To control the pest infestation, spray of Bifenthrin 10% EC @ 300 ml/acre with chlorantraniliprole @ 18.5% SC @ 60 ml/acre
As a biological control, use Bavaria Basiana @ 250 g / acre.
Spray Thiophanate Methyl 70% W / W @ 300 gram / acre for control of fungal diseases
Use as a biological control of fungal diseases by Pseudomonas fluorescens @ 250 gram/acre
For good flowering and growth in green crops, use Homobrassinolide @ 100 ml /acre as spray.
Do spray this on the new moon day of April.

Organic insecticide is a product based on fungi and bacteria, viruses and botanical produce.
It protects crops, vegetables and fruits from pests.
They also help in increasing the production of crops.
Being a product based on organisms and flora, organic pesticides decompose in the soil.
Bio-pesticides do not cause any harm to health and the environment.
It is an eco-friendly option as organic pesticide leaves no residue in the soil.
Organic insecticides control only targeted pests.

Neem coated urea means that urea is formulated by coating neem on it
To make neem coated urea, neem oil is applied over urea.
This coating acts as a nitrification inhibitor. Neem-coated urea is absorbed slowly
Due to this, nitrogen nutrient is readily available as per the requirement of crops and crop production is also increased.
Neem coated urea seems to use about 10% percent less urea than normal urea, saving 10% percent urea.

Leaf miner insects are very small in size. They burrow inside the leaves and make tunnels. This makes white lines on the leaves. The adult moth is light yellow in color and the young insect is very small, footless and yellow in color.Insect infestation begins on the leaves. This insect creates a spiral tunnel in the leaves. Photosynthesis process of plants is affected . Hence, the leaves fall.
Chemical management: – Abamectin 1.9% EC @ 150 ml / acre or Spinosad 45% SC @ 75 ml/acre or Cyantraniliprole 10.26% OD @ 300 ml/acre for control of this pest.
Biological treatment: – As a biological treatment, use Beauveria bassiana @ 500 gram/acre.

This disease is caused by bacteria and fungi, which damages the watermelon crop.
Symptoms of bacterial wilt infection can be seen on all parts of infected plants.
The leaves turn yellow, then the whole plant dries up and dies.
Watermelon crop starts drying in patches
For prevention of this disease use Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 gram/acre or Kasugamycin 3% SL@ 400 ml/acre
As biological treatment use Pseudomonas fluorescens @ 250 gram/acre.

These insects are small in size, red in color and are found in large quantities on the soft parts of green gram crops like leaf, flower bud, and twigs, webs are visible on the plant on which mites reside. Sucking the sap out of the plant’s soft parts, weakens them and in the end the plant dies
Chemical management: – Spray Propargite 57% EC @ 400 ml/acre or Spiromesifen 22.9% SC @ 200 ml/acre or Abamectin 1.8% EC @ 150 ml/acre.
Biological management: – As a biological treatment, use Beauveria bassiana @ 500 gram/acre.

This pest causes a lot of damage in brinjal crops in both the stages of its life cycle i.e. nymph and adult.
They suck the cell sap out of cotton plant leaves and inhibit plant growth. These insects are also the cause for the secretion known as a sooty mold developed on the plant.
Brinjal crops can get completely infected during high infestation and even if the crop is fully developed, there is a chance of infestation of this pest which can cause the leaves of this crop to dry up and fall.
Management: – For the prevention of this pest, Diafenthiuron 50% SP @ 250 gram/acre or Flonicamid 50% WG @ 60 ml/acre or Acetamipyrid 20% SP @ 100 gram/acre or Pyriproxyfen 10% +Bifenthrin 10% EC 250 ml/acre.
Biological management: – As a biological treatment, use Beauveria bassiana @ 500 gram/acre.

Due to excessive heat and climate changes, the virus spreads in sponge gourd crops.
Its carrier is the white fly. It sits on the leaves. Jumps fields from one to the next one. This leads to a spread of virus infection in vegetables.
The symptoms of this disease are seen in all the stages of the plant, due to which the veins of the leaves turn yellow and a mesh-like structure is formed on the leaves.
Chemical management: To prevent this, use Acetamiprid 20% SP @ 100 gram /acre or Diafenthiuron 50% WP @ 250 gram/acre or Pyriproxyfen 10 % + Bifenthrin 10% EC @ 250 ml/acre .
Biological management: As a biological treatment, use Beauveria bassiana @ 500 gram/acre.

The bitter gourd crop is prominently planted with some of Zayed’s major crops.
In the Zayed season as the temperature changes and the temperature rises.
Because of the rise in temperature, the seeds of bitter gourd do not germinate completely.
Due to which the yield of the farmer is greatly affected.
To prevent this, sow the seeds of bitter gourd with seed treatment only.
In 10–15 days of sowing, give phosphorus solubilizing bacteria in bitter gourd crop @ 500 gram/acre with vigormaxx gel @ 1 kg /acre from the ground.
The use of these two products increases the germination percentage in the bitter gourd crop.
