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.

Damage and control measure of fruit fly in watermelon

The attack of fruit flies is serious in watermelon crops, The adult fly lays eggs in flowers or directly on fruits. and after hatching the larvae bore holes in the fruit and eat the fruit from inside, which can cause heavy rotting inside the pulp. Also, small spots are formed on the skin of the fruit where the eggs are laid, and the damage caused by this makes the fruit more susceptible to fungal and bacterial infections. Due to this, there is a reduction in production and the quality of the fruit is also affected.

Control: For control and monitoring of fruit flies, apply Melon fly lure @ 10 traps per acre in the field under IPM. And spray Neemgold (Azadirachtin 0.3% EC) @ 1600 ml per acre in 150-200 litres of water.

Keep these precautions at the time of storage in potato crop

  • After digging potatoes, the most important work for it is storage. Potatoes can be protected from spoilage for many months if stored properly. Following are the things to keep in mind while storing potatoes –

  • The temperature of 2 to 4 degrees centigrade is suitable for storing potatoes for a long time.

  • Potatoes should not be stored in the refrigerator. This adversely affects the taste of potatoes.

  • Always store potatoes in a well-ventilated place.

  • The storehouse should be completely dry. If there is moisture in it, potato storage and its safety are adversely affected.

  • If you are storing potatoes in a box, keep a newspaper between each layer of potatoes.

  • Periodically inspect the storehouse.

  • Do not clean the potatoes with water before storing them. This increases moisture in the potato and reduces storage.

  • If the potatoes appear green, brown, shrivelled and have an odour, then take out such potatoes. Also, separate the sprouted potatoes as well.

Know the method of making Silage

  • To make grain crops such as maize, sorghum, bajra, oats, etc., when crops have a milking stage, cut them into small pieces 2-5 cm.

  • The pieces of chopped green fodder should be spread on the ground for a few hours so that some amount of excess water will blow away.

  • Now put the chopped fodder in the pre-prepared silo pit or silage pits.

  • Fill the cutting pieces in the pit by pressing it with feet or a tractor, so that the air between the feed comes out.

  • After filling the pit, add thick polythene and seal it well.

  • After this, apply a layer of soil about one foot thick from the top of the polythene cover so that air cannot enter.

  • Starts making silage from pieces of green fodder, because in the silo pit there is no air and water, the pressed fodder creates lactic acid, which does not spoil the silage for a long time. 

  • Open the pits as per the requirement of fodder for at least 45 days for feeding the animals.

Thrips damage and management in Garlic Crop

Thrips are found in the garlic crop, which is quite microscopic. Both males and females of this kit cause damage. These insects attack the delicate parts of the plants, and as a result, the plants are not able to grow. This pest pierces the leaves by scratching and sucking all the sap from the leaf, due to which the leaves curl, the plant starts drying up, and also the bulbs of affected plants remain small.

Management: To control thrips damage, spray Tafgor (Dimethoate 30 EC) @ 264 ml or Fipnova (Fipronil 5% SC) @ 400 ml per acre in 150 to 200 litres of water.
