Disease Management

Due to seasonal changes, pests and diseases affecting the standing wheat crop can cause a lot of trouble. Farmers should deal with it by taking the right steps at an appropriate time otherwise the entire crop may go to waste.

Presently wheat crop is grown in the fields. Continuous changes are being seen in the weather. Sometimes it rains and sometimes cold wave continues to wreak havoc, hence due to changes in weather, pests and diseases affecting the standing wheat crop can cause a lot of problems. Farmer brothers should deal with it by taking the right steps on time otherwise the entire crop may go to waste. There is not just one type of disease in wheat but different types of diseases. Farmers are advised to maintain and monitor their crops regularly.

Mahu or Lahi

Mahu or Lahi insects are black, green, and brown with wings and wingless. Its infants and adults suck the juice from leaves, flowers, and earrings. Due to this, there is huge damage to the crop and the crop gets ruined. Let us tell you about the advice given by scientists to save the crop from the attack of this insect.

Sow the crop on time.

Do not use insecticides if the number of ladybird wasps is sufficient.

Apply a yellow noose or sticky substance on a yellow tin sheet and make it stand in the field with the support of wood. Flying Lahi will stick to it.

Spray 50 grams of Thiomethoxam 25 percent WG per hectare or Quinalphos 25 percent EC in 2 ml per liter of water.

Harda disease

According to scientists, the possibility of attack and spread of this disease increases due to drop in atmospheric temperature after rain in this season. Brown and yellow spots are found on the leaves and stems of wheat plants. Preventive measures should be taken as soon as the environment becomes favorable for this disease.

Select disease-resistant varieties at the time of sowing.

Before sowing, seed treatment should be done with 2 grams of Carbendazim 50 percent soluble powder or 5 grams of organic fungicide per kilogram of seeds.

As soon as a suitable environment for the fungus is created in the standing crop, spray 2 kg of Mancozeb 75 percent soluble powder, 500 ml of Propiconazole 25 percent EC per hectare, or 1 ml of Tebuconazole EC per liter of water.

Alternaria Blight

Due to Alternaria blight disease, spots are formed on the leaves, which later turn yellow and scorch the edges. To control this disease, spray 2 kg of Macozeb 75 percent soluble powder or 2 kg of Geneve 75 percent soluble powder per hectare.

Kidney disease

In Kalika disease, the black dust of fungus fills the ears in place of the grains. Even a healthy ear gets infected due to fungal spores falling in the air. This is a seed-borne disease. Farmer brothers should keep these things in mind to prevent this disease.

Sow disease-free seeds.

-Sow the seeds after treating them with Carbendizing 50 soluble powder at the rate of 2 grams per kilogram.

-Carefully cover the infested ear along with the grain with a plastic bag and destroy it after cutting.

-Do not use diseased farm produce as seeds.

After rice, wheat is one of the most important crops grown in India. Wheat is sown in the Rabi season. But for the production of wheat farmers have to go through a lot of difficulties. Mainly farmers have to face losses due to different plant diseases in the wheat crop. There are different types of diseases that wheat crop can catch but the disease that harms the most are rust related diseases. Rust diseases are of three types mainly brown rust,  black rust and yellow rest.

Leaf rust/ Brown rust

Potash, also known as potassium (K), is one of the necessary macronutrients required for healthy growth of all plants, including bananas. Potassium plays an important role in various physiological processes within plants, such as photosynthesis, enzyme activation, osmoregulation and nutrient. Lack of potash in banana plants has a harmful effect on their growth, fruit growth and overall productivity. Let's know about the major symptoms of lack of potash in banana plants and various strategies to manage it ....

Symptoms of lack of potash in banana plants

Potassium deficiency in banana plants is manifested through many types of symptoms that affect different parts of the plant. It is important to understand these symptoms for timely diagnosis and effective management. Some common symptoms of lack of potash in banana plants are as follows:

Symptoms of lack of potash on leaf

Brown of the edges of the leaf: The edges of the old leaves become brown and dry, this condition is called leaf scorching. 

Turning of leaves: The leaves turn up or downwards, which distorts their form. 

Yellowing among the veins: The yellow of leaf tissue between the veins, called interveinal chlorosis, is a common symptom.

 Leaf necrosis: In severe cases, necrotic (dead) spots may appear on the leaves, reducing photosynthetic activity.

Symptoms of lack of potash on fruit

Lowering fruit size: Lack of potash reduces the size of fruits, which affects the market price of bananas. 

Uneven ripening: Fruits do not cook evenly, making it challenging for business producers.

Symptoms of lack of potash on stem and bunch

Stagnant growth: The overall growth of banana plants may stop, resulting in reduced yield.

Small flakes: Fruits become small and thin due to lack of potash.

Symptoms of lack of potash at the root

The roots are less empowered due to weak cell walls and become more sensitive to diseases.

Management of lack of potash in banana plants

Management of lack of potash in banana plants includes a combination of potassium on soil and leaves as well as other agricultural functions to improve the absorption and use of potassium. Some measures are being suggested here to effectively manage the lack of potash, such as:

Soil testing

Start by testing soil to assess potassium levels in the soil. This will provide correct guidance regarding determining the severity of deficiency and using proper potassium fertiliser.

Fertiliser application

Use potassium -containing fertilisers, such as potassium sulphate (K2SO4) or potassium chloride (KCL), based on soil testing recommendations. Include potassium fertilisers in the soil during planting or during the development of bananas. Monitor soil pH, as highly acidic or alkaline soil can reduce the amount of potassium. Adjust the pH level if necessary.

Spraying on the leaves

In cases of severe shortage, spraying potassium on the leaves is a quick remedy. To protect the leaves from burning, dissolve potassium nitrate or potassium sulphate in water and apply it in the morning or afternoon. Apply organic wet grass around banana plants to preserve soil moisture and maintain soil temperature continuously. This improves potassium absorption by roots.

Balanced nutrition

Ensure that other essential nutrients, such as nitrogen (N) and phosphorus (P), are also present in sufficient amounts to prevent the imbalance of nutrients. Bananas require 150-200 grams of nitrogen (n), 40-60 grams phosphorus (P2O5) and 200-300 grams of potash per plant on the basis of soil and variety. The use of one-fourth nitrogen (N) and one-third potash (K2O) in the time of flowering (reproductive phase) has been found to be beneficial. At the time of flowering, the use of nitrogen delays the ageing of the leaves and improves the weight of bunches and using a third potash improves finger filling. Using the total quantity of nitrogen and potassium into farming from a banana plant prepared by tissue enhancement provides maximum benefit by using the total amount of nitrogen and potassium such as the first planting, 45 days after planting, the third-90 days later, the fourth, the fourth -135 days later; 5th-180 days later. The entire amount of phosphorus fertiliser should be put at the time of last ploughing or while filling the pit.

Water management

Proper irrigation to avoid water stress, as drought conditions can increase potassium deficiency.

Crop circle

Change the banana crop with other plants to reduce the risk of lack of nutrients in the soil.

Disease and pest control

Immediately solve any disease or insect infection, as they can put pressure on the plant and obstruct the nutrients.

Harvesting and removing dead leaves

To promote the development of a healthy, potassium-efficient decnus, regularly damaged or sort dead leaves.

Monitoring and adjustment

Constantly monitor the plant's response to potassium treatments and adjust fertiliser experiments accordingly. Finally, it can be said that lack of potassium in banana plants has a significant negative effect on growth, fruit quality and yield. To overcome this deficiency and ensure a healthy and productive banana crop, timely diagnosis and proper management are necessary, including soil testing, fertiliser experiment and agricultural functions. By applying these strategies, banana producers customise potassium nutrition and get better overall plant health and fruit production.
