How Pseudomonas fluorescens is a beneficial bacteria

Pseudomonas fluorescens is a friendly bacterium that helps to prevent bacterial and fungal diseases that spread through the soil and air. At the same time, it also produces growth elements in plants, which helps the plant to grow and results in yield. It acts as an intra-body(Systemic) bio-control.

When Pseudomonas fluorescens is sprayed, it produces some secondary metabolites such as gibberellic, Auxins, which help the plant to remain green, and also increase resistance against stress, and disease in the plant.

We can use it through the soil application, spray, and seed process. It effectively controls diseases like root rot, stem rot, damping off, wilt, red rot, bacterial blight, etc. in the different types of crops, fruits & vegetables.

Symptoms of Micronutrient Deficiency in Onions

Symptoms of Micronutrient Deficiency in Onions

In onion crops apart from nitrogen, phosphorus and potash, micronutrients are also essential, and their deficiency results in production and productivity. For example, pungency in onions is due to an element called allyl propyl disulphide. In order to increase this pungency and increase production, sulfur is required in onions.

Sulphur: All leaves young and old appear uniformly yellow, Also, in plants deficient in sulphur, the leaves lose their green color.

Manganese: The veins of the leaves turn yellow and start burning, the color of the leaves fades and they start turning upwards. Crop growth is stunted, onion bulb formation is delayed and the upper part (neck) of the bulb becomes thick.

Copper: Proper amount of copper is necessary for the development of the upper cover of bulb in onion crop. Copper deficiency causes young leaves to turn white at the tip and curl into a spiral, or curl to the right side of the plant, as well as softening of the tuber sheath, becoming pale yellow and thin.

Calcium: Calcium is an important nutrient for crop growth and storage quality. Due to its deficiency, the new leaves start drying suddenly without turning yellow, as well as the leaves become very narrow.

Symptoms and control measure of stem gall disease in coriander

Coriander is a multi-useful spice crop. Coriander leaves and seeds are both useful. Stem gall disease is very harmful in coriander crops, this disease is caused by a fungus called Protomyces macrosporus.

Symptoms of Stem gall Disease: Galls appear on the leaves and stems of plants affected by this disease. Even before flowering, the pathogenic fungus attacks the soft branches and twists their top part. Also, the infected part swells, as well as small tumour-like swellings appear on the stem near the ground. Initially, it appears shiny but later splits and becomes hard, and in advanced infection, these pustules (swellings) are also formed on the upper part of the stem. When the attack occurs in the inflorescence, seed production is reduced.

Control: To reduce stem gall disease, maintain optimum moisture, and destroy diseased crop residue by burning. treat the seed with Bavistin (Carbendazim 50% WP) @ 2 g/kg before sowing. If symptoms appear in standing crops, spray Novacone (Hexaconazole 5% SC) @ 400 ml/acre with Monas Curb (Pseudomonas fluorescens) @ 250 g/acre in 150 to 200 litres of water.

Importance of Boron in crops and deficiency symptoms in watermelon

Importance of Boron in crops: It Stabilises plant tissues and improves crop vigour. Boron works with calcium and also helps in increasing the quality of the crop. Along with this, Boron has a major contribution to making flowers and fruits in crops. It plays a major role in preventing flower and fruit drops and in increasing the size and quality of fruits.

Deficiency Symptoms: The younger leaves of the plant are smaller than normal and may be curled. Yellowing proceeds from the marginal area between the veins towards the centre. The youngest leaves show necrotic tips. Growing points dieback and flowering and fruit set are poor. Also, flexibility is necessary for the proper development of fruit but due to the deficiency of Boron, there is hardness in the fruit skin and due to this these cracks appear on the fruits.
