Dear Prof. Houda,

Thanks for the invitation. Azardirachtin has a tetranorternepoid chemical agent in Neem leaves that acts on the mitotic cells and blocks the microtubule polymerization. It also alters the activities of many genes and proteins. It acts as a botanical insecticide preventing many fungicidinal, microbial and bacterial attack on fruits.

Melia and Mentha leaf extracts of green and matured fruits also puts up a strong defense against post harvest fuingi and bacteria.

I am not any expert of the field. But following plants are used in my locality for storage of grains. These may act.

1. Pongamia glabra.

2.Azadirachta indica

The air dried matured leaves are kept in between.

Thanks.

Thanks Dear Shibabrata Pattanayak

the answer, traditions in each region are usually the result of accumulated good experiences. This is what we are looking for in agricultural heritage, and we try to develop it in scientific research

Dehydration is one good approach .

Melia and Mentha leaf extracts of green and matured fruits also puts up a strong defense against post harvest fuingi and bacteria.

The most widely used plants extracts are of the neem tree (Azadirachta indica) and its leaves, chinaberry (Melia azadrach) and marigold (Tagetes spp). They are being used to manufacture natural or bio insecticides, which possess fungicidal and insecticidal properties.

Article suggested by Dr Aparna Sathya Murthi is quite relevant and interesting

@ Dr. K. N. Sheth Sir

Article suggested by Dr. Aparna Sathya Murthy does not deals with protection of fruits from post-harvest diseases using plant extracts, rather it deals with protection of stored food grains.

Thanks to colleagues for their participation in enriching scientific dialogue and references, the problem of treating materials such as seeds prepared for storage from the treatment of fruits prepared for trading or export or storage is different content moisture and different temperature.

@ Arvind Singh

I fully agree with you. It deals with protection of stored grains

Azadirchta indica leaf extracts can preserve your crops against fungal attacks

...It is preferable to use alternatives to chemical pesticides such as plant extracts (medicinal and aromatic plants as well as wild plants) to protect plant production from diseases caused by fungal, bacterial, viral and nematode organisms that affect various field and horticultural crops and cause significant losses to the national economy. And reduce the losses caused by the infection both during the planting season or in the post-harvest to keep pace with the recent trends in disease resistance. The medicinal and aromatic plants grown in the Arab world are regularly basil, mint, mint, lemon grass, garlic, red, thyme and others.

Sudanese Shata Extract:

  The fruits of these plants contain the material of the capsaicin and resinous substances are medically important to strengthen the wall of the stomach and remove rheumatic pain. The water extract of the plant is resistant to many pathogens, whether microbial or insect, on the vegetable total. Also, spraying with the cucumber extract prevents the spread of the cucumber mosaic virus and the tick spot virus in the cucumber.

Basil extract:

  And the part used from this plant is the leaves, which contain oil pilot with the substance of camphor and linalol, which is used as a stalk of gases and in the perfume industry. Water and alcohol extracts are used for basil against plant pathogens such as fungi (A.alternata, Curvularia tuberculata). The basil extract inhibits mycelium growth as well as germination of F.oxysporum, which causes wilt disease in the ring. The basil extract is also used as an antimicrobial agent for the growth of many fungi that are loaded with seeds such as A.flavus, A.niger and F.moniliforme

Neem extract:

Neem is an insect repellent. Plant extracts of this plant are used against insects as well as against plant diseases caused by microorganisms. Use this extract successfully against Fusarium spp. As well as against fungi (A.flavus B.theobromae). Neem extract is more effective than other extracts inhibiting mycelium growth and reducing germination rate of the following fungi (A.alternata, A.flavus, C.lunatus, F.moniforme, R.stolonifer ) In stored grain as well as in stored pear fruits. The water and alcohol extracts of Niem are successfully used to resist many insect pests, whether in stored agricultural crops or when used in field application conditions.

The neem extract reduces the virulence of fungus-borne fungi such as beans with increased germination rate and increased germination rate. This indicates that in addition to the Neem extract, it is safe for the environment. It gives protection to seeds treated against fungal infections, leading to increased production.

Thank you for participating in answering the question

Interesting question, unfortunately it is not within the field of specialization and practical.

Dear Dr. Kawas

The widely studied plants in this context are:

Plant extracts: Neem (Azadirachta indica),

Garlic (Allium sativum), Eucalyptus (Eucalyptus globulus), Turmeric (Curcuma Longa), Tobacco (Nicotiana tabacum) andGinger (Zingiber officinale).

Essential oils: Nettle (Urtica spp.), Thyme (Thymus vulgaris, Linn.), Eucalyptus (Eucalyptus globulus), Rue (Ruta graveolens), Lemon grass (Cymbopogon flexuosus) and Tea tree (Melaleuca alternifolia).

Gel and latex: Aloe vera.

Dear Dr. Seied Mehdi Miri

hank you for your scientific contribution

Lantana Extract, Lemon Grass Extract, Neem Extract, etc.

A considerable amount of work has been carried out all over the world on the effect of plant extracts on the quality and shelf life in various fruit and vegetable crops. Please take a look on pending files >I hope it useful for your request:

Thank you Dear Dr.Nihad Mohammed and Dr. Ali Alhayanyf or your scientific contribution

there are many plant extracts and bacteria as biocont

There are many plant extract as Pepper and turmeric extract...etc
