Save sugarcane crop from red rot disease, know the control measures

28/08/2024 Wednesday August 28th, 2024

This fungus mainly attacks the stem and leaves of the sugarcane plant. the leaves of the upper portion of the plant become pale and dark red which ultimately droop down.
The stem splits and many red-coloured longitudinal streaks are formed on it. The red colouring is mainly in the vascular bundles and often in the pith.
At severe infection, the stem gets rotten, shrinks at internodes, and becomes dull in appearance. The pathogen attacks all the parts above the ground, but more especially the canes stems, and midribs of leaves.
When the diseased canes(stems) are split open, the tissues of the internodes will be found longitudinally reddened (normally white or yellowish-white) in one or more internodes.
This red colour is interrupted by white patches extending crosswise on the canes. In the case of true red rot, the red colour extends through many internodes.
To control it, remove the affected bunches at the initial stage and drench the soil with Carbendazim 50 WP (1 gram per 1 liter of water).

Early blight outbreak in tomato will have serious consequences

27/08/2024 Tuesday August 27th, 2024

Symptoms of early blight usually begin after the first fruit set on tomato plants, starting with a few small, brown lesions on the lower leaves.
As the lesions progress, they take on the shape of target-like rings with dry, dead plant tissue in between.
The surrounding plant tissue turns yellow, then brown before the leaves die and drop from the plant.
While early blight does not directly affect the fruit, loss of protective foliage from exposure to direct sun can damage the fruit. That condition is called sun-scald.
Control: Novacrust (Azoxystrobin 11% + Tebuconazole 18.3% SC) @ 240-400 ml/acre or M 45 (Mancozeb75 % WP) @ 600-800 gm/acre.

Nematodes cause heavy damage to crops, know the control measures?

26/08/2024 Tuesday August 27th, 2024

Nematodes are like very thin threads. Their body is long cylindrical and the whole body is without segments.
Nematodes, living inside the soil, form a knot in the roots of the crop and damage the crop.
Biological treatment is the best solution to control this pest.
Soil treatment is the best way to control this pest.
As a chemical treatment, treat the soil with Furi (Carbofuran 3% GR) @ 10 kg/acre.
Before sowing the crop, apply Nematofree (Paceilomyces Linnaeus) @ 1 kg/acre mixed with 50-100 kg FYM in an empty field.
Whenever this product is used, keep in mind that it is contemporary in the field.

Symptoms and prevention measures of powdery mildew and downy mildew in chilli

25/08/2024 Friday August 23rd, 2024

Powdery and Downy mildew is a fungal disease that highly affects the leaves of chilli crops.
This disease is also known as Bhabhutiya disease.
In Powdery mildew, white powder appears on the upper surface of the leaves of the chilli plant.
In Downy mildew yellow spots appear on the lower surface of the leaves, after some time these spots become large, angular, and turn into a brown powder.
This brown powder deposits as a layer on the leaves making the process of photosynthesis difficult.
To control the disease, spray Novacrust (Azoxystrobin 11% + Tebuconazole 18.3% SC) @ 240-400 ml/acre or Tesunova (Tebuconazole 10% + Sulfur 65% WG) @ 500 g/acre.
As a biological treatment, spray Tricho shield combat(Trichoderma viridi @ 500 g/acre or Monas- curb(Pseudomonas fluorescens)@ 250 g/acre.

How to take care of soybean crops in low rainfall

24/08/2024 Friday August 23rd, 2024

We all are aware of how the climate is changing these days.
This shifting pattern of weather makes heavy rainfall in some areas and low rainfall in others, it is in these areas of low rainfall that soybean crop is being affected drastically.
Soybean crops suffer a lot due to drought and high temperatures.
The symptoms of water scarcity are seen in the soybean crop in the form of dullness and plant wilting causing the plant to come under stress which makes the growth of the soybean plant reduced or stunted.
To manage it, apply NovaMaxx (Gibrelic Acid 0.001%) @ 180-200 ml/acre or MaxxRoot (Humic Acid + Potassium + Fulvic Acid) @ 100 g/acre

Leaf spot disease will cause severe infection in brinjal leaves, learn preventive measures

23/08/2024 Friday August 23rd, 2024

Infection of brinjal plants with leaf spot disease initially appears on older leaves. These spots are small, chlorotic globular to oval in shape that turn brown to brown on the upper leaf surface and light brown on the lower leaf surface.
As the disease progresses, concentric rings of diseased tissue may develop with sporulation in the center of the spots. Wounds can dry out, causing cracks in the tissue and the development of shot holes.
In this disease, the infection does not spread on the fruits of brinjal, but due to severe infection on the leaves, there can be a huge reduction in yield.
To control the disease use Novaphanate (Thiophanate methyl 75%wp) @ 300 gm/acre + Monas-curb (Pseudomonas fluorescens 1% w.p.) @ 250gm per acre.

Identify the symptoms of Holcus Leaf Spot disease in maize and adopt preventive measures

22/08/2024 Thursday August 22nd, 2024

The bacterium Pseudomonas syringae causes round, white to light tan spots on leaves. Spots typically have a brown border. This disease often appears after a rainstorm when warm (75-85°F is favourable). During storms, splashing water disperses the pathogen and wounds that occur (such as by blowing soil) enable the pathogen to enter the leaf.
and may merge into necrotic cystic striae, eventually drying up and leading to papery eyelids. 2 Holcus leaf spot can also be seen in eyespot as a fungal disease, which also has circular spots with a brown border and yellow halo.

Preventive Measures

Plant late to avoid wet climatic conditions that spread the disease.
Avoid working in fields when foliage is wet.
Avoid overhead irrigation.
Clear the field of weeds and alternative hosts.
Do not compost or leave plant residues near plantations.
Remove infected plants immediately and burn their remains.
Crop rotation with non-susceptible crops is recommended.

There will be an outbreak of Mealybug in cotton, prepare for rescue

21/08/2024 Wednesday August 21st, 2024

Mealybug-infested plants show symptoms of leaf curl, bushy shoots, and wrinkled or curled and tufted leaves during the vegetative growth phase of the cotton crop. Due to this the plants start drying up and become dwarf and dry.
Adult and juvenile mealybugs bore into both soft and hard plant tissue and suck the sap. It can occur at all stages of cotton crop development.
Although damage is often minor, damage can be worse in areas where the crop is under stress (eg areas with poor drainage).
Heavy infections that start quickly and persist tend to secrete a sticky substance. Because of this, they act as carriers of many diseases.
For its chemical treatment, use Novalaxam (Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC) @ 50ml + Bave Curb (Beauveria bassiana) @ 250 gm/acre.

Outbreak of Fall Armyworm in Maize will be fatal, learn preventive measures

20/08/2024 Tuesday August 20th, 2024

This insect invades all stages of the maize crop. Normally, it attacks the leaves of maize, but in case of more outbreaks, it also damages the corn. Larvae attack the upper part of the maize plant or the soft leaves, small holes are seen on the leaves of the affected plant.

How to Identify Fall Armyworms?

They are green, pink, brown, or black in colour.
Between their eyes, a white colour pattern like the letter Y inverted English is made.
They have trapezoid pattern spots on each segment of their body.

Control

ProfeNova Super (Profenofos 40 % + Cypermethrin 04 % EC)@ 400 ml/Acre,
Emanova (Emamectin Benzoate 5 % Sg) @ 100gm/acre, Cover (Chlorantraniliprole 18.5 % W/W Sc) @60 ml/Acre + Bave Curb (Beauveria bassiana) @ 250 gm/acre.

Bacterial leaf spot will cause heavy damage in tomatoes, do quick treatment

19/08/2024 Saturday August 17th, 2024

Moist weather and heavy rains are favourable for the development of the disease. Most outbreaks of this disease can be traced to heavy rains in the region.
Small, brown, water-soaked, circular spots surrounded by a yellow halo appear on infected leaves.
Leaf infection on older plants occurs mostly on older leaves and can cause severe defoliation.
Most of the symptoms appear on green fruits. First appear as small, water-soaked spots that later become larger.
The centres of these lesions become irregular, light brown and slightly sunken with a rough, scaly surface.
Ripe fruits are not susceptible to this disease. The surface of the seed becomes contaminated with bacteria if it remains on the surface of the seed for some time.
To protect the crop from this disease, use Monas-curb (Pseudomonas fluorescens 1% WP) @ 250 gm/acre.
