    SEED-BORNE AND POST-HARVEST DISEASES OF CUCUMBER (CUCUMIS SATIVUS L.) AND THEIR MANAGEMENT *Dilip Kumar Sharma Vardhaman Mahaveer Open University (VMOU), Kota, Rajasthan, India *Author for Correspondence ABSTRACT Cucumber (Cucumis sativus L.) is a valuable crop with diverse pharmacological spectrum grown as tropical annual climbers cultivated File Size: KB. Forty seed samples of different rice cultivars from eastern Vidarbha zone viz. Sakoli and Navegaon Bandh (Distt. Bhandara), Sindewahi (Chandrapur) and Tharsa (Nagpur) tested 8 months after storage by blotter method showed infection of 14 fungi of 11 genera, where as 30 samples of another season from Sakoli and Sindewahi tested immediately after harvest carried infection of 19 fungi of 11 Cited by: 1.

    Fortunately, many broad-spectrum seed treatment fungicides are available to protect against soil-borne fungi, as well as protect against seed-borne diseases. Many contain mefenoxam or metalaxyl fungicides that protect the seedling against water mold fungi, such a Pythium or Phytophthora. This book is the result of finding of a research conducted on rice seeds collected from Syangja district of Nepal. There were forty-five different varieties of rice seed including improved, hybrid and local; collected from farmers and tested in laboratory to find different fungal : Shalik Ram Adhikari.

Internally seed-borne smut diseases. Loose smut of barley and wheat are internally seed-borne and carried as a small colony of fungus inside the seed embryo rather than as spores on the seed coat.

These are the only internally seed-borne smuts that occur in Australian cereal crops. Contaminated machinery and soil do not transmit these diseases.

A germination test would be recommended. For Stagonospora, loose smut and Fusarium head blight a fungicide seed treatment may be necessary. A number of fungicides are labeled for use as seed treatment fungicides on winter wheat.

These seed treatment fungicides protect germinating seed and young seedlings from seed-borne and soil-borne pathogens. However, the causes, symptoms, preventive and curative control measures of some most important seedborne diseases of wheat, are being summarized. Loose smut: This disease is caused by a fungus.

Most of the studies on biological control of seed-borne fungal diseases have focused on wheat, barley, rice, sorghum, cowpea, soybean, chickpea, pea and bean among the field crops, as well as on. translucens) are the other seed borne diseases in wheat. Detection methods of seed borne pathogens The selection of a method depends upon the purpose of the test i.e.

whether the seeds are to be tested for seed certification, seed treatment, quarantine etc. If for quarantine purposes, then highly sensitive methods are preferred, which. Seed borne pathogens causes diseases at various stages of crop growth from germination of seed up to crop maturity and heavy losses have been observed, caused by seed borne pathogen in various crops.

Seed borne pathogens causes seed and seedling rots, i.e. pre- and post- emergence losses, diseases at various stages of crop growth like root rot.

Infected wheat seeds are the carrier of pathogens for long-distance dissemination. Major impact of seed borne diseases in wheat is not only the yield reduction but also deteriorate marketable. vMajor seed-borne diseases are adequately controlled through chemical or heat treatment vSeed testing provides information to allow appropriate choice of fungicides vWheat is at risk from changes to EU legislation that may lead to a ban of some seed treatment chemicals – leading to a higher risk of resistance to existing chemicals.

The presence of the several seed-borne organisms on seeds of barley, corn, oats and wheat was usually accom­ panied by blighted seedlings and reduced germination. Autoclaved soil consisting of equal parts of soil and sand provided a satisfactory substratum in which seedling blights of barley, oats and wheat were readily determined.

Non-chemical seed treatments include physical treatments, microbial treatments and treatments with other agents of natural origin like plant powders or extracts.

Physical treatments with hot water, aerated steam, or dry heat have successfully been applied to a range of crops against a range of target pathogens and are in commercial use Cited by: Historically flag smut, caused by the fungus Usrocystis agropyri, was an important disease of wheat in r, in recent years this disease has been controlled with the use of resistant varieties and treatment of seed with fungicides.

Plant Pathology MF Fungicide seed treatments are an important part of wheat production in Kansas. Seed treatments can effectively manage seed-borne disease, such as common bunt, flag smut, and loose smut; generally improve stand establishment; suppress the development of root rot diseases; and inhibit the development of foliar diseases in.

Dithane M, Bavistin, Captan, Thiride, Foltaf, Vitavax and hot water treatment reduced the seed-borne infection with different seed- borne infection, but there is an urgent need of development of seed certification standards for different seed-borne diseases of rice where chemicals are not the final answers and also need more sensitive Author: L.P.

SEED DISINFECTANTS Control Seed-Borne Diseases—Stimulate Germination Here is an easily applied dust treatment which has proven effective in controlling such seed-borne diseases as bunt or stinking smut of wheat; stripe disease of barley; loose and covered smuts of barley and oats and covered kernel smut of sorghum.

offers the cheapest. Among all the groups of seed borne pathogens, fungi play significant role in causing seed borne diseases.

Considerable amount of research works have been conducted on the association of seed borne fungal pathogens with rice and on the control of seed borne infection of the crop with chemicals but little work has been carried out on the control Author: Abdul Bari, Dipok Kumar.

evaluated for their effect on seed germination and control of major seed-borne pathogens of sunflower. Two sunflower cultivars, HO-1 and NK, naturally infected with important seed-borne fungi were treated with these fungicides at,g/kg. All.

Seed-borne infection of maize (Zea mays L.) by fungal pathogens was studied using 22 seed samples of maize collected from different locations in Burkina moist blotter test was used to detect fungi on seeds. Experiment was also performed on seedlings raised from naturally infected maize seed samples in order to evaluate the transmission of fungi from seeds to seedlings.This volume continues the series of books on “Plant Pathology in the 21st Century”, and contains the papers given at the 10 th International Congress of Plant Pathology (ICPP ) held in Beijing, Augustconcerning seed health.

Many pathogens are transmitted throughout infected seeds and propagation fact that propagation material production is very much.Loose Smut, all on wheat, are included in the plant import regulations of a number of European and American countries.
