Abstract

Fusarium yellows causing yellow, brown and wilted leaves. The gladiola bulbs rot and reduce quantity, quality and marketability of flowers. Four Fusarium species, especially F. oxysporum. f.sp. gladioli cause this disease. These fungi can survive as microconidia, macroconidia, clamydospore and mycelium, in the soil. Bulb discoloration is the most common symptom of the disease. In storage, the diseased corms get softened, mummified and wrinkled. Many researches have been carried on to investigate the methods of disease control, but all were unsuccessful so far. Disease management is based on resistant varieties, chemicals, cultural and biological measures. However, a combination of several methods provides a better opportunity to manage this disease.

Abstract

Nazerian E. and Sayad S. 2017. Fungi parasitic viruses. Plant Pathology Science 6(2):97-104.

Several viruses have been identified as parasites of some fungal isolates that cause chestnut blight, canola stem rot, wheat head blight, corn smut, and a number of molds and yeasts. These mycoviruses reduce growth, proliferation and pathogenicity and cause abnormal pigmentation in the mycelium, or mutations in the host fungus. These viruses can be transmitted to other isolates of the same fungus or other fungi by hyphen anastamosis. Therefore, identification of hypovirulent and infected isolates of pathogenic fungi to viruses and their use for plant protection against highly pathogenic isolates and plant diseases management is recommended.

Abstract

Nazerian E, Sayad S (2021) Control methods of plant pathogens in irrigation system. Plant Pathology Science 10(1): 117-127.     Doi: 10.2982/PPS.10.1.117.
 
Many plant pathogens can spread into irrigation water in farms, gardens or greenhouses and cause disease in various crops. So far, a large number of plant pathogens including 43 fungal-like organisms, 27 fungi, eight bacteria, 26 viruses and 13 nematodes have been isolated and reported from water sources and water transmission systems. In many greenhouses, various pesticides are used to prevent the spread and control of these pathogens, which imposes costs, soil or water pollution, and the possibility of resistance in pathogens. Different methods of water treatment to control aquatic pathogens in the irrigation system using chemicals such as chlorine, chlorine dioxide, copper, silver and ozone, physical methods such as water filtration, heat, ultraviolet rays and the use of biosurfactants such as rhamnolipid and  nitrapyrin, are described in this article.
