Crop management in 10–15 days of sowing in bitter gourd crop

This stage of green bitter gourd crop, has problems related to pest infestation, fungal diseases, and growth and development.
To overcome all these problems, in the bitter gourd, it is very important to manage crops during 15-20 days of the crop.
To control insect infestation, spray Acetamiprid @ 20% SP@ 100 gram/acre
As a biological control, use Beauveria Bassiana @ 250 gram/acre.
Spray of Carbendazim 12% + Mancozeb 63% @ 300 gram/acre for control of fungal diseases
Use Pseudomonas fluorescens @ 250 gram/acre as a biological control of fungal diseases
For good crop growth and development, use vigermaxx gel @ 400 gram/acre + 19: 19: 19 @ 1 kg / acre as spray.

Leaf miner insects are very small in size. They burrow inside the leaves and make tunnels in cucumber crops . This makes white lines on the cucumber leaves. Insect infestation begins on the cucumber leaves. This insect creates a spiral tunnel in the leaves. Photosynthesis process of cucumber plants is affected . Hence, the leaves fall.

Abamectin 1.9 % EC @ 150 ml / acre or Profenofos 50 % EC @ 500 ml / acre or Thiamethoxam12.6 % + Lambda Cyhalothrin 9.5% ZC@ 80 ml / acre or Cyantraniliprole 10.26 % OD @ 250 ml / acre

It plays an important role in the formation of enzymes that prevent or reduce the damage of cells. Due to its deficiency the bones of the animal become weak due to which deformity arises.

The color of the animal’s hair becomes abnormal, such as the coat of a red cow becomes yellow and the coat of a black cow becomes muddy or gray.

Usually this disease affects the leaves of the green gram crop, invading the lower and upper part of the leaves.
Yellow to white powder appears on the upper and lower surface of the leaves of green gram.
For managing them use, Azoxystrobin 11% + tebuconazole 18.3% SC @ 300 ml /acre or Azoxystrobin @ 300 ml/acre
Spray: Trichoderma viride @ 500 gram/acre + Pseudomonas fluorescens @ 250 gram/acre as a biological treatment

Cobalt is very essential for ruminant animals as it is found in very limited quantities in their body. The lack of cobalt occurs in food items because the soil in which it was grown also lacked cobalt in the soil.
It helps in the synthesis of vitamin B12, which helps in the formation of red blood cells and growth.
Lack of appetite due to cobalt can cause weakness, Pica, Diarrhea, and infertility.

Soil electrical conductivity (EC) is an indirect measurement that has a very deep correlation with the physical and chemical properties of soil. Soil electrical conductivity is an indication of the availability of nutrients in the soil.
The measurement of soil alkalinity and acidity is also highly dependent on soil electrical conductivity (EC).
The greater concentration of salts in the soil leaves a detrimental effect on the absorption of nutrients.
Very low electrical conductivity levels indicate low available nutrients, and very high EC levels indicate nutrient excess. Those with low EC are often found in sandy soils with low organic matter levels, while high EC levels are found in high organic soil content (more clay).
Soil texture, salinity and moisture are the soil properties that most affect EC levels.

Good soil means the soil that has an ideal pH value and the amount of nutrients available in the soil is very balanced.
Good soil is best for plant growth.
This type of soil particles have very high water holding capacity.
It holds sufficient amounts of water in it and air circulation is also good in it.

Cauliflower are sown in the nursery before being transplanted in the main field.
When Cauliflower nursery is being prepared, the ease of weeding, irrigation should be kept in mind.
Before sowing, treat Cauliflower seeds with Carbendazim 12% + Mancozeb 63% @ 2.5gram/ kg seed or Carboxin 17.5%+ Thiram 17.5% @ 2.5 ml/kg seed.
Soil treatment of nursery is very necessary before nursery sowing treatment is done for prevention of soil borne diseases. For this use FIPRONIL 0.3% GR @ 25 gram/nursery and Trichoderma viride @ 25 gram / nursery and seaweed + amino + Mycorrhiza @ 25gram / nursery
Also keep in mind that at the time of sowing the soil must have sufficient moisture.

White grubs as the name suggests are white colored insects that live as a grub in a field whose dormancy period is in the winter.
They initially damage chilli plant roots. Symptoms of white grub include a complete withering of the plant or stunting the growth of the plant resulting in the plant dying.
Usually this pest should be controlled in the month of June and in the early week of July.
For this, do deep plowing in summer use Metarhizium culture (kalichakra) along with FYM (2 kg + 50-75 kg) per acre for control of white grub
But if infestation of white grub is visible even in the immature stage of chilli crop, then chemical treatment can also be done to control this pest.
use FENPROPATHRIN 10% EC 10% EC @ 500 ml / acre, CLOTHIANIDIN 50.00% WG @ (Dantotsu) 100 g / acre as soil mix.

Watermelon is the main crop of cucurbits crops .
Thus it is very important to manage nutrition in this stage.
Lack of nutrients causes the problem of flower shedding in the watermelon crop.
And excessive flower shedding greatly affects fruit production in the watermelon crop.
To prevent flower shedding use Micro-nutrients @ 250gram/acre.
To prevent flower drop,use Homobrassinolide @ 100 ml/acre or Paclobutrazol 40% SC @ 30 ml/acre.
