Soybean will be harmed by Gram pod borer, take immediate precautions

20/09/2024Posted on
Soybean will be harmed by Gram pod borer

  • The larvae feed on all plant parts but prefer to eat flowers and beans.

  • The black hole appears on the affected pod and larvae appear hanging out of the pod while eating.

  • The tiny larvae feed the chlorophyll by scratching of leaves, which causes the leaves to become skeletal.

  • In the severe stage of infection, the leaf falls down and the plant dies.

    Management of Gram Pod Borer in Soybean:-

  • To control adult pests, use a pheromone trap @ 8-10/acre.

  • First, spray Profenova (Profenofos 50% EC) @ 300 ml/acre + Tricel (Chlorpyrifos 20% EC) @ 500 ml/acre.

  • Second Spray Profenova super (Profenofos 40%EC + Cypermethrin 4 %EC) @ 400 ml/acre + Emanova (Emamectin benzoate 5% SG) @ 80-100 gm/acre.

  • Third spray Ampligo(Chlorantraniliprole 9.3% + Lambda Cyhalothrin 4.6% ZC)@ 100 ml/acre or Larvin (Thiodicarb 75% WP) @ 250 gm/acre.

  • Spray the Bave Curb (Beauveria bassiana) @ 250 gm/acre as a biological treatment.

Management of Fruit borer in chilli

  • A circular hole is noticed at the base of the pedicel—the premature dropping of flowers and pods. The fruit turns to white colour.

  • Mainly borer larvae have grown up into the fruits.

  • Early instar larvae by making a circular hole feed on young pods and flower buds. The larvae usually feed the seeds in mature fruit.

  • At the time of feeding the larvae head inside the pod and the rest of the body outside from fruits.

  • To control adult pests, use a pheromone trap @ 8 -10 /acre.

  • First spray Profenova(Profenofos 50% E.C.) @ 300 ml/acre + Tricel (Chlorpyrifos 20% EC) @ 500 ml/acre.

  • Second Spray Profenova (Profenofos 50% EC @ 300 ml/acre + Emanova (Emamectin benzoate 5% SG) @ 80-100 gm/acre.

  • Third spray Emanova (emacactin benzoate 5% SG) @ 80-100 gm/acre + Denitol (fenpropathrin 10% EC) @ 250-300 ml/acre.

  • Fourth spray Ampligo(Chlorantraniliprole 9.3% + Lambda Cyhalothrin 4.6% ZC)@ 100 ml/acre or Larvin (Thiodicarb 75% WP) @ 250 gm/acre.

  • The Bave Curb (Beauveria bassiana) @ 250 gm/acre as a biological treatment.

Protect Soybean crop from Anthracnose or Pod Blight

11/09/2024Posted on
Protect Soybean crop from Anthracnose or Pod Blight

  • It is a seed and soil-borne disease.

  • If the infected seed is planted, early disease development may result in damping-off (plant death by seed or seedling rot).

  • During the flowering stage of soybean, red to dark brown irregularly shaped spots appear on the stem, petiole and pod.

  • Later these spots get filled with black structures (acervulai) and small thorn-like structures of the fungus.

  • Symptoms of this disease are yellow-brown veins on leaves, curling and falling.

How to control Anthracnose or Pod Blight in Soybean crop:

  • Healthy seeds should be selected for sowing.

  • The seed should be treated with Vitavax(Thiram+Carboxin) @ 2 g/kg of seed before sowing.

  • Continuous sowing in the same plot should be avoided.

  • Spray the crop with Carmanova (Carbendazim 12% +Mancozeb 63% WP)@ 400 Gm/Acre at 10-15 days intervals, first spray be given on the appearance of symptoms.

  • In Several Attacks, spray the crop with Tebuconazole 25.9% EC @ 200 ml/Acre.

Importance of Zinc or good crop production

10/09/2024Posted on
Importance of Zinc or good crop production

  • Zinc is needed strongly for the development of plants. It is one of the eighth essential micronutrients. In India, Zinc (Zn) is now considered the fourth most important yield-limiting nutrient in agricultural crops.

  • Deficiency in Zinc might result in a significant reduction in crop yields and quality. In fact, yield can be reduced by over 20% before any visual symptoms of the deficiency.

  • In plants, Zinc is a key constituent of many enzymes and protein synthesis.

  • It plays an important role in a wide range of processes, such as growth hormone production and internode elongation.

  • It is often deficient in alkaline, rocky soil.

  • Young leaves of Zinc deficient plants are small with yellow interveinal mottling.

  • Soil application of Zinc Sulphate @ 20 kg/acre is recommended to reduce the damage.

Problem and control of Septoria leaf spot in tomato crop

The development of this disease is more at 25 °C temperature . This fungus can occur at any stage of crop development, but symptoms usually first appear on older leaves and stems when the plant is bearing fruit. In that case the infection is also visible on the  fruit stalk, stem and inflorescence. Due to this, small round watery spots are formed on the leaves. Whose edge is dark brown.

Preventive Measures

For biological control, take spray of Monas-curb @ 500 gm + Combat @ 500gm + Silicomaxx @ 50 ml per acre, @ 150 to 200 liters of water.

Chemical Control 

To control this disease, take a spray of Merivon @ 100 ml + Silicomaxx @ 50 ml per acre @ 150 to 200 Ltr of water.

Chilli crop will be attacked by sucking insects, be alert

07/09/2024Posted on
Chilli crop will be attacked by sucking insects

Sucking pests like aphids, jassids, and thrips are the main problem of chilli crops. These pests damage by sucking plant sap from the green part of the plant so the leaves are wrinkled and premature defoliation. Infestation of sucking insects can increase the chances of diseases spread by fungi and viruses.

Therefore, timely control of these insects is necessary:

  • Spray of Profenova (Profenophos 50% EC) @ 400 ml/acre. OR

  • Spray of Asataf (Acephate 75% SP) @ 250 gm/acre. OR

  • Spray of Lamnova (Lambda-cyhalothrin 4.9% CS) @ 200-250 ml/acre. OR

  • Spray of Fipnova (Fipronil 5% SC) @ 300-350 ml/acre should be done.

Collar rot disease increasing in chilli crop

  • Collar rot disease increasing in chilli crop, identify the symptoms and treat them

  • The lower portion of the stem is affected by the soil-borne inoculum.

  • Its main symptom is a deformity in the plant.

  • Exposure and necrosis of underlying tissues may lead to the collapse of the plant.

  • Near the ground surface on the stem may be seen the mycelia.

  • Lack of plant vigour accumulation of water around the stem and mechanical injuries help in the development of this disease.

    Control of Collar rot in Chilli

  • Destroy the debris of diseased plants.

  • Crop rotation and ensure good drainage.

  • Sowing of seeds on raised nursery beds.

  • Treating seeds with Carmanova (Carbendazim 12%+ Mancozeb 64%) @ 3 gm/ kg seeds before sowing.

  • Soil drenching with Bavistin(Carbendazim 50%) @ 300 gm/acre or Novaxyl (Metalaxyl 8%+Mancozeb 64%) @ 500 gm/acre.

Symptoms and control measures of Gall midge in paddy crop

05/09/2024Posted on
Symptoms and control measures of Gall midge in paddy crop

The life cycle of this insect is 14 to 20 days. Due to this, there is a decline in crop production by 25 to 30 percent or more. The maggots of this insect enter inside by eating the top of the new bud and a gall is formed at the base of the tiller which later takes the form of a pipe like structure. Thereby forming a ponga similar to “onion-leaf” or “silver-shoot”. panicle does not produce in the affected tiller.  

Control measures:

To control this pest, take a spray of Thianova 25 @ 40gm +  Silicomaxx @ 50 ml/acre @ 150 to 200 Ltr of water. Or apply Fury @ 10 kg per acre in soil.
