Management of gummy stem blight in the pumpkin, watermelon, melon crop

Choose healthy seeds.
Inspect transplantation and uproot the infected plants and leave the farm out of the field.
spray chlorothalonil 75% WP @ 350gm / acre or
spray tebuconazole 25.9% EC @ 200 ml / acre solution.

In this disease, infection is visible on almost every part of the plant except the roots.
A Yellowness/greenness occurs at the edges of the leaves, while spots start occurring on their surfaces.
The wound is formed on the stem of the plant which is infected by this disease. Then a black-coloured gummy substance starts releasing from this wound.
On the string, brown spots become black spots which later go to the wound.
In bottle gourd seeds have medium-brown, dark spots.

Destroy infected plants and plant debris.
Use of disease-free seed.
Seed treatment with carbendazim @ 2 gm/kg seeds before sowing.
Use Propiconazole 25% EC @ 80-100 ml/acre when the disease appears on the muskmelon plant.

Diseases are more common in sandy soil.
The plant shows a distinctive dark brown necrotic rot of the crown and upper portion of the taproot.
This decay extends around the stem and girdles the plant.
The affected area turns soft and mushy
affected plants show wilting symptoms

Adopt clean cultivation and remove alternate hosts, particularly weeds.
Follow crop rotation.
Avoid cropping mosaic prone season and areas.
Acephate 75% SP @ 80-100gm/acre and add antibiotic chemicals like streptomycin 20 gm/pump for better control. or
Acetamiprid 20% SP @ 100 gm/acre and add antibiotic chemicals like streptomycin 20gm/acre for better control.

This viral disease is transmitted through sap and vector aphids.
In infected plants, the younger leaves unfold very late and show complete chlorosis followed by green vein banding.
The older leaves exhibit prominent dark green raised blisters. the malformed leaves assume a filiform shape.
Vegetable growth, flowering and productivity are also affected adversely.
Severely affected vines do not bear fruit.

Plucking and destroying affected leaves helps in reducing Downy Mildew in watermelon crop.
Plant seeds of disease-resistant varieties.
Crop rotation and sanitation reduces the severity of the disease.
Drench with thiophenate methyl 70% WP at the rate of 300 gm/acre.
Spray Metalaxyl 8%+Mancozeb 64% WP at the rate of 500 gm/acre.
Spray pseudomonas fluorescens @ 500 gram/acre.

Gramophone Moong Samriddhi Kit includes all the essential ingredients that are required to get more production from the moong crop.
The Moong Samriddhi Kit contains various kinds of beneficial bacteria.
Potash and phosphorus bacteria, Trichoderma viridi, humic acid and Rhizobium bacteria are prominent among these bacteria.
This kit has been prepared by mixing all these microorganisms.
The total weight of this kit is 6 kg, and one kit is used for one acre of area.

The cucumber plant is a shallow-rooted crop and thus it doesn’t require any deep intercultural operations.
Prune all secondary shoots up to 5 nodes, to improve yield & fruit quality.
Staking of plants is helpful in checking the rotting of fruits.
