Management of Mosaic Virus Disease in Sponge Gourd :-

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.

Plastic Mulching protects against insects, diseases and weeds in watermelon crop.
Weeds can be controlled by black polyethene and also prevents soil erosion from air, rain and irrigation.
Transparent polyethene is used to control soil-borne diseases and maintain moisture conservation.

Ridge gourd is a good source of calcium, phosphorus, iron and vitamin A.
It is cultivated in hot and humid climates.
The temperature should be 32-38 degree centigrade.
The drainage method is considered more suitable for sowing luffa.
During summer, its crop should be irrigated at regular intervals of around 5-6 days.
If its harvesting is delayed, then the fibers become hard fibers.

Cucurbitaceae crops are a subtropical vegetable and require hot and humid climatic conditions for its fast growth and higher yield.
Night and Day temperature of 18-22° C and 30-35° C respectively is optimum for its proper growth and high fruit set.
The seed germination is fast at the temperature range of 25-30° C.
The crop grown at optimum temperature has a higher proportion of female flowers and fruit per plant.
