Identification and control Measures of white fly in chilli crop

02/09/2022Posted on

White fly

 In 15-35 °C temperature, the incidence of this pest is high. The young and adults of this insect suck the sap by sticking to the lower surface of the leaves. They not only damage the crop by sucking the sap, but also release a sticky substance on the plants on which, black mold develops. Plants affected by this appear yellow and oily. In its infestation, the leaves of the plants wither and twist. Which is known as leaf curl disease.

Control measures

  • For biological control, take a spray of Bave-curb @ 500 gm per acre @ 150 -200 liters of water.

  • For chemical control, spray Meothrin @ 136 ml + Silicomaxx @ 50 ml per acre @ 150 -200 liters of water.

In soybean, at the stage of flowering and grain filling, dark brown irregularly shaped spots appear on the stem, flower stalk and pods with yellowing. Which are later covered by fungal black and thorns-like structures. Yellow-brown leaves, twisting and shedding are the main symptoms of this disease.Seeds infected with pod blight do not germinate.

Control measures

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

For chemical control, take a spray Tesunova @ 500 gm or Folicure @ 250 ml + Silicomaxx @ 50 ml per acre @ 150-200 liters of water.

Bacterial blight disease and prevention measures in paddy crops

30/08/2022Posted on

Bacterial blight disease:- This disease is caused by a bacterium called Xanthomonas oryzae, in which the leaves start drying from the tip or from the edges. The dried edges are irregular and crooked. Diseased plants become weak, they also have less tillers. And the new leaves of the affected plants are of light brown color. And scorching from the bottom turns yellow or brown and the whole plant dies, if there is more outbreak, it destroys the crop up to 50% or more.

biological management

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

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

27/08/2022Posted on

Fusarium wilt:

Fusarium wilt is a common disease of the chilli crop. It is a seed and soil borne disease caused by a fungus called Fusarium oxysporum. 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 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 when the right moisture environment is provided by 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 the growth of mycelia is visible on the heap, apply the mixture in one acre area.

Nutrient Management at Booting Stage in Paddy Crop

26/08/2022Posted on

Nutrient management in the booting stage is an important measure to get a higher yield of paddy. In paddy crop, the booting stage starts in 60-65 days after transplanting. At this stage, do nutrition management in a proper way like this –

Nutrition management:- To get high yield of paddy, it is very necessary to use urea @ 40 kg + MOP @ 10 kg + Calbor @ 5 kg per acre.

Urea:- Urea:- Urea is the biggest source of nitrogen supply in paddy crops. With its use, there is no problem of yellowing and drying in the leaves. and Urea accelerates the process of photosynthesis.

MOP (Muriate of Potash):-  Potassium plays an important role in transporting the sugar synthesized in the rice plant to all parts of the plant. Potassium promotes the efficiency of natural nitrogen. Increases immunity in plants. 

 Calbor:- This product contains a combination of Calcium 11% + Magnesium 1.0% + Sulphur 12% + Potassium 1.7 + Boron 4% which are essential for nutrition, growth, photosynthesis, transport of sugars and cell wall formation. Calbor is compatible with most of the commonly used fertilizers and agro chemicals.

Symptoms and control measures for mite damage in chilli crop

25/08/2022Posted on

Symptoms of damage

These are very small insects that suck the sap from the lower surface of the leaves, causing the leaves to turn downwards. Due to sucking of sap from the leaves, white to yellow spots appear on the surface of the leaves. As the infection becomes more severe, first the leaves start showing silver color and later these leaves fall.

Control measures

For its control, take a spray of Oberon (Spiromesifen 22.90% SC) @ 160 ml or Omite (propargite 57% EC) @ 600 ml + silicomaxx @ 50 ml per acre.

The causative agent of this disease is Choanephora cucurbitarum, the fungus of the disease usually infects the upper part of the plant, flowers, leaves, new branches and fruits. In the initial stage, water-soaked areas develop on the leaf. The affected branch dries up and hangs. In severe infection, the fruits turn brown to black in color, a layer of fungus can be seen on the infected part.

Measures for identification and prevention of die back disease in chilli crops

22/08/2022Posted on

Dieback:- Dieback is a major problem in chilli. This disease is caused by a fungus called Colletotrichum capsai. Yellow spots appear on the fruit of chilli. Due to which the fruit gets rotten. Due to this disease, the ends of the tender twigs rot backwards. The entire top of the branch or plant withers. Several black dots appear scattered on the surface of the affected twigs. The top or some lateral branches become dead or in case of severe infestation the whole plant dries up. Partially affected plants produce fewer and lower quality fruits.

Control measures

To control, spray Score (Difenoconazole 25% EC) @ 50 ml per 100 liters of water. Or spray Index (Myclobutanil 10% WP) @ 80 g + SilicoMaxx  @ 50 ml per acre at the rate of 150 to 200 liters of water.

Major caterpillars and their control measures in soybean crops

21/08/2022Posted on

Soybean pod borer

This insect causes a lot of damage to the soybean crop, the attack of this insect occurs in the early stage of soybean crop, first this insect first damages the soft parts of the plant, after that the soybean pod and Later damages the seed, this caterpillar enters the soybean pod and damages it by eating the pod.

Gram pod borers

Gram pod borers attack all parts of the plant, but they prefer to eat flowers and pods. Black holes appear on the affected pods and larvae are seen hanging out of the pods while feeding. The adult caterpillar eats the chlorophyll of the leaves, which causes the leaves to turn into skeletons. In the severe infestation, leaves break off and the plant dies.

Tobacco caterpillar. 

The larvae of this insect scrape the leaves of soybean and eat the chlorophyll of the leaves, due to which a whitish yellow color appears on the eaten leaves. They also damage stems, buds, flowers and fruits when attacked excessively. Due to which only the sticks are visible on the plants.

Control measures

Spray, Plethora (Novaluron 05.25 % + Indoxacarb 04.50 % SC) @ 350 ml or fame (Flubendiamide 39.35% w/w SC) + Silicomaxx @ 50 ml,  per acre @ 150 to 200 liters of water.

Identification and control of leaf folder pests in paddy crops

20/08/2022Posted on

Leaf folder :- The female of this insect lays eggs in groups near the veins of the leaves of paddy. The larvae come out from these eggs in 6-8 days. These larvae first eat soft leaves and later, by making silky thread with their saliva, twist the leaf from the edges and eat it by scraping it inside. The outbreak of this pest is more in the month of August-September. Paddy leaves appear white and scorched in the affected field.

control measures

For its control, Spray Super 505 (Chlorpyriphos 50% + Cypermethrin 5% EC) @ 280 ml or Lamonova (Lambda-cyhalothrin 4.90% CS) @ 100 ml + Silicomaxx @ 50 ml per acre @ 150 -200 liters of water.
