Measures for identification and prevention of Fusarium wilt disease in chilli crops

Fusarium wilt disease

Fusarium wilt is a common disease of the chilli crop. It is a seed and soil-borne disease. Affected plants suddenly wither and gradually dry up. Such plants are easily uprooted when pulled by hand. Due to Fusarium wilt, the roots of the diseased plants turn brown and black from the inside. When the diseased plants are cut, the tissue appears black. The leaves of the plants wither and fall down. This disease progresses due to excessive moisture and heat in the air and soil and due to the availability of moisture through irrigation.

Biological management

  • Apply Combat (Trichoderma viride @ 500 gm) or Monas Curb (Pseudomonas fluorescens 1% WP) @ 500 gm per acre.

According to TNAU  

Mix @ 2 kg  Combat (Trichoderma Viride) formulation with 50 kg FYM, sprinkle water over it and cover with a thin polythene sheet. After 15 days when mycelia growth is visible on the heap, apply the mixture in one acre area.

Know why seed treatment is important in wheat crops

seed treatment in wheat
    • Seed Treatment protects plants from soil and seed-borne diseases like smut, and bunt disease.

    • This treatment also prevents the attack of root humus and keeps the crop healthy.

    • Seeds do not get spoiled, which leads to more seed germination.

    • Healthy plant growth occurs.

    • Cost is reduced and production is increased.

Field preparation and nutrient management for okra

Nutrient management for okra

Land preparation

For good growth and root development of plants, it is necessary to have friable soil. After harvesting the previous crop, ploughing should be done with a soil turning plough and after that, FYM at the rate of 4 tonnes + Speed kompost @ 4 kg per acre should be applied evenly in the field. and apply 2-3 ploughing with the help of a harrow. If the soil moisture is less then first irrigate, then prepare the field, and lastly make the field level by rolling the levelar.

Nutrient Management

At the time of sowing or within 25 days of sowing, DAP 75 kg + MOP 30 kg + Tricoat Maxx  (Organic Carbon 3%, a mixture of humic, fulvic, organic nutrients) @ 4 kg + TB3 (Nitrogen Fixing, Phosphate solubilizing and Potassium mobilizing biofertilizer consortia) @ 3 Kg + Taba G (Zinc Soluble Bacteria) @ 4 Kg + Neem Cake 50 Kg + Agromin ((Zinc, Iron, Manganese, Copper, Boron & Molybdenum) @ 5 Kg + Magnesium Sulphate @ 5 kg, mix all these together and apply it evenly on per acre basis.

Symptoms and prevention measures of Fusarium wilt / Uktha disease in gram crops

Fusarium wilt in gram crops

This is the most harmful fungal disease of Bengal gram, the disease can affect the crop at any stage. Its main symptom is yellowing and browning of the leaves from the bottom up and finally, the plants wither and dry up. When the stem is cut, the internal tissue appears brown, due to which nutrients and water do not reach all parts of the plant. And the plants start dying. The collar and root area appear dark brown or black in color when the plants are uprooted.

Preventive measures

To avoid this disease, at the time of sowing, it should be treated with Combat (Trichoderma viride 1.0% WP) 10 gm/kg seed and now for its prevention, Apply Combat (Trichoderma viride 1.0% WP) @ 1 kg per acre on the soil evenly and apply light irrigation.

Know irrigation management and critical stages in potato crop

Know irrigation management and critical stages in potato crop
  • In potato crops, giving little water at a time at short intervals is more beneficial for the yield.

  • First irrigation must be done after 10 days but within 20 days after transplanting. By doing this, germination will be faster and the number of tubers per plant increases, due to which the yield increases twice. 

  • By applying the first irrigation on time, the manure applied in the field is used by the crops from the beginning as per the requirement. 

  • The time of two irrigation seeds can be increased or decreased depending on the soil condition of the field and experience. However, do not keep more than a 20 days gap between two irrigations. 

  • Stop irrigation 10 days before digging. By doing this, the tubers will come out clean during digging. Keep in mind, give water only till half the farrow in each irrigation.

  • Water management is very important in certain stages of growth (critical stages)-

1) Emergence Stage

2) Tuber set Stage

3) Tuber growth stage

4) Final crop Stage

5) Pre-harvest irrigation Stage.

Damage to soil due to burning in stubble field

Damage to soil due to burning in stubble field

  • Burning the stubble causes a lot of damage to the environment and increases pollution

  • Due to burning of crop waste, beneficial microorganisms found in the farm are destroyed.

  • This reduces crop yields and reduces soil fertility.

  • Due to burning of straw, there is emission of gases like methane, carbon monoxide, carbon dioxide etc. in the atmosphere. Due to which there is fog in the atmosphere

  • Structure of organic materials in the soil is disturbed due to burning of stubble.

Control of brown plant hopper in paddy crop

Brown plant hopper will cause heavy loss in paddy crop
  • The nymph and adult of this insect, which ranges from brown to white in colour, lives near the base of the stem of the plant and causes damage to the plant.

  • Eggs are laid by the adult near the main vein of the leaves.

  • The shape of the egg is semilunar and the colour of the nymph is white to light brown.

  • The damage done by the planthopper is seen as yellowing of the plant.

  • Brown planthoppers suck the sap of the plant. Due to this, the crop dries in a circle, which is known as hopper burn.

  • For its control spray THIAMETHOXAM 75%SG @ 60 gm/acre or BUPROFEZIN 15 % + ACEPHATE 35 % WP@ 500 Gram/acre.

  • As a biological treatment.use  Bavaria Basiana @ 250 gm /acre.

Why, when and how to add mycorrhiza in the field

Mycorrhiza effect on chilli plant
  • Improve plant root growth and development. 

  • Increase the uptake and mobilization of phosphate in all crops.

  • Increase and facilitate nutrient and translocation from the soil and root cuticle parenchyma to Xylem, Phloem, elements like nitrogen, potassium, iron, manganese, magnesium, copper, zinc, boron, sulphur and molybdenum.

  • Effective in overcoming the stress conditions like drought, disease incidence and deficiency of nutrients.

  • Enhance product quality and increase the immune power of the crop.

  • Its supplement root hair in water absorption hence prevents reduction in crop relative water content of cells and helps to overcome drought.

  • Soil Treatment – Mix Premium mycorrhiza 2 kg per acre in 50 Kg of well-decomposed FYM/compost/vermicompost/field soil and incorporate in the soil before sowing/transplant.

  • Broadcast the above mixture in a standing crop 25-30 days after sowing.

  • Through drip irrigation – Use of Mycorrhiza as drip irrigation 25-30 days of sowing at the rate of 100 gram/acre in standing crop.

Know very important information before cultivating barley

Know very important information before cultivating barley
  • To get more production in barley cultivation, the most suitable time for sowing its seeds is from 15 October to 15 November. However, depending on the circumstances and supply of fodder, it can be sown even till the first week of December.

  • Delay in sowing due to low temperatures results in late germination. It should be sown in rows at a distance of 25 cm with a plough or seed drill.

  • The seeds should be sown at a depth of 4 to 5 cm. Weeds can be easily controlled in crops sown in rows. By treating the seeds before sowing with Carbendazim 12% + Mancozeb 63% (Karmanova) @ 2.5 grams per kg of seeds, germination is good and the crop remains free from seed-borne diseases.

  • For crops sown for fodder, 100 kg seeds should be sown per hectare. But for grains, only 80 kg seeds are required per hectare.

Know essential information before cultivating fenugreek

Know essential information before cultivating fenugreek
  • Fenugreek can be cultivated in all types of soils provided there is a high amount of organic matter in the soil. However, it gives good results in well-drained sandy loam and sandy loamy soils. It can tolerate soil pH values of 5.3 to 8.2.

  • Regarding its seed rate, 12 kg seeds per acre should be used for sowing in a one-acre field.

  • To prepare the field, plough the field two to three times until the soil becomes loose and then level the land. When last ploughing, apply 10 to 15 tonnes of well-decomposed cow dung per acre. Prepare a 3×2 meter flat seedbed for sowing.
