About the Practice

The fruits of vegetable crops like pointed gourd (Trichosanthes dioica) and bitter gourd (Momordica charantia) turn yellow prematurely. Their outward look is just like ripe fruits. This reduces the yield. Then there is also the problem of aphid and larvae attack on these crops. To overcome both the problems, the farmer with intuitive sense has developed an indigenous medicine by boiling 1 kg each of "Aankol" (Alangium salvifolium) leaves, neem (Azadirachta indica) leaves and tobacco (Nicotiana tabaccum) powder in 8 L water till half the quality i.e., 4 L is left. After cooling, 250 g of the stock solution is mixed in 10 L water and 3 - 4 pumpsful are sprayed per 0.25 ha of land. According to the experience of farmer, aphids and larvae are destroyed in two days after the spray and premature ripening of fruits also stops.

Practice Details

Crop: Pointed gourd and Bitter gourd
Crop Family: Cucurbits
Crop Scientific Name: (Trichosanthes dioica), (Momordica charantia)
Crop Vernacular Name: Parval, Karela
Formulation: Liquid solution of 1 kg each of "Aankol" (Alangium salvifolium) leaves, neem (Azadirachta indica) leaves and tobacco (Nicotiana tabaccum) powder in 8 L water
Ingredients: leaves of "Aankol" (Alangium salvifolium) and neem (Azadirachta indica), tobacco (Nicotiana tabaccum) powder

PAS 1:

"To enhance sprouting of seeds and hasten production of
fruits: The primary raw materials required to induce quick sprouting and fruiting are oil of Alangium Salvifolium"

PAS 2:

"In antifungal activity assay, the extracts of Ficus racemosa, Moringa oleifera, Azadirachta indica, Cassia alata, Senegalia catechu etc. displayed promising antifungal activities against both of the isolate A and B. The outcome of this research work would be helpful for detection and developing nature-friendly control approach of the two devastating diseases of bitter gourd."

PAS 3:

"Biological effects of neem on the pupation of Henosepilachna vigintioctopunctata Fab. On bittergourd"

PAS 4:

"Purification and characterisation of an antifungal protein, MCha-Pr, from the intercellular fluid of bitter gourd (Momordica charantia) leaves - The MCha-Pr protein has some similarity to the pathogenesis-related proteins from Atropa belladonna (deadly nightshade), Solanum tuberosum (potato), Ricinus communis (castor bean), and Nicotiana tabacum (tobacco). Analysis of the circular dichroism spectra indicated that MCha-Pr predominantly contains α-helix and β-sheet structures. MCha-Pr had inhibitory effects towards a variety of fungal species and the 50% inhibition of fungal growth (IC50) for Alternaria brassicae, Cercospora personata, Fusarium oxysporum, Mucor sp., and Rhizoctonia solani are 33 μM, 42 μM, 37 μM, 40 μM, and 48 μM, respectively. In addition, this antifungal protein can inhibit the germination of A. brassicae spores at 12.5 μM. These results suggest that MCha-Pr in bitter gourd leaves plays a protective role against phytopathogens and has a wide antimicrobial spectrum."
