Insect management in watermelon

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.

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.
