Farmers should protect their wheat crops from these diseases

Farmers should protect their wheat crops from these diseases

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.

Different types of Rust diseases found in wheat crop

Different types of Rust diseases found in wheat crop


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

Piccinia Recondita Triticeae is the fungus that causes brown rust and is found nationwide in India. This disease begins from the Himalayas and North India and from the Nilgiri Hills in South India and after staying a live in These areas at Travels via air and water to the Planes and
infecting the wheat crop in the plane areas.


Identification: This infection can be identified by the pattern of its growth in the start Orange coloured dots appear randomly on the leaves of plants and gradually these increase and cover the entire leaves, foliage and the stems of the plant. These leaves start to die and hinder the sunlight. This also results in decreased size and weight of the wheat grains. With increasing temperature the colour of these parts on the underside of the leaf turns black and after this point the disease does not expand further. This disease can cause a 30% reduction in the total produce.


Stripped rust/ Yellow rust

It is caused by a fungus called puccinia Striiformis. Symptoms of this infection are the appearance of yellow stripes on the leaf and with time these spread gradually to the entire leaf surface. Yellow powder is also found fallen on the ground in this situation the crop is said to have yellow rust disease. If the infection starts before the tillering stage the crop does not mature. This infection starts from the foothills of the Himalayas and spreads to the northern plains. It decreases with increasing temperature and the yellowness of the leaves goes black. In the central and South India due to high temperatures this disease is generally not found.


Stem rust/ Black rust

It is caused by a fungus called puccinia Graminis Triticeae. It starts in the Nilgiri and Palni Hills and is generally found in the south and Central India. This infection reaches North India at the time of ripening of the crop. This is why its effect is negligible in North India. This disease generally spreads above 20 degree celsius temperature. It's symptoms are the appearance of chocolate colour on the stem and the leaves on the plant. The different varieties of seeds sold in the central and southern part of India are generally resistant to black Rust. But varieties like Lok-1 are prone to infection by Black rest. In recent years new varieties of this fungus U.G.-99 has been found in some African countries.


Controlling the infection


To cure these three diseases farmers should adopt scientific methods to fight Rust. Spraying the following Chemicals as required can control wheat rust disease: Propiconazole(Tilt 25%EC) or tridimefan belitan 25%EC or spraying Techonazole (1ml in 1000L). Fungicides can be spread after 15 days as per the requirement.


The most important nutrient for banana cultivation, symptoms of lack of potash and technique of managing it

The most important nutrient for banana cultivation, symptoms of lack of potash and technique of managing it

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.

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.
