Induction of Resistance in Abaca Against Wilt Disease Complex caused by Fusarium oxysporum f. sp. cubense (E. F. Smith) and Ralstonia solanacearum (Smith) Yabuuchi et. al. Using Chemical and Biological Elicitors Abstract Resistance in plants has been reported to be inducible using biological and or chemical elicitors. Fusarium wilt and bacterial wilt diseases are two major diseases hampering abaca production in the Philippines. This study was conducted to evaluate the efficacy of biological

caused by Fusarium oxysporum f.sp. ciceris is a soil and seed borne disease affecting chickpea whichis widely distributed where chickpea is grown. It causes yield losses in the range of 12 to 100 % depending on the level of resistance of the genotype and suitability of environmental conditions for disease development. Management of soil borne diseases mainly involves use of preventive measures because it is harder to control the disease once established. Thiram and carbendazim are used in majority of

Viroids are plant pathogens that consist of a short stretch (a few hundred nucleobases) of highly complementary‚ circular‚ single-stranded RNA without the protein coat that is typical for viruses.[1] The smallest discovered is a 220 nucleobase scRNA (small cytoplasmic RNA) associated with the rice yellow mottle sobemovirus (RYMV).[2] In comparison‚ the genome of the smallest known viruses capable of causing an infection by themselves are around 2kilobases in size. The human pathogen hepatitis D is

Diseases of melon ( Cucumis melo ) in Arizona Alternaria leaf spot Alternaria leaf spot is caused by the fungus Alternaria. The fungus produces dark‚ multicelled spores on host tissue only when there is substantial moisture‚ usually during summer rains. The spores are easily carried in wind and splashing water and infect only the leaves. Brown necrotic spots appear on the leaves wherever spores germinate and infect leaf tissue (photo 1). Spots are small at first then may enlarge and coalesce to

Pest and diseases and control measures Introduction Since man started to live on agriculture‚ he has to involve in a constant struggle to protect crops from other animal and adverse environmental conditions. In order to get a maximum crop production and profit from the cultivation farmer has to pay a special attention and bare an additional cost for crop protection even today. Crop protection has become even more important due to the introduction of high yielding crop species. Pest and diseases

Pathogens are everywhere. They are in people‚ animals‚ and the environment. Pathogens come in a wide variety. The types are fungal‚ bacterial‚ viral‚ and other parasites. All pathogens can be dangerous‚ but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness‚ they differ in the way they are transmitted‚ the way they are treated‚ and the diseases they cause. First‚ the way fungal and

blood and other infectious materials that may contain blood borne pathogens. OSHA standards are meant to protect employees from potentially hazardous and infectious materials by using a blend of personal hygiene‚ personal protective equipment‚ work placement training and practices. Putting all of this together and following the OSHA standards and precautions greatly reduces the risk of contracting and transmitting blood borne diseases. The current OSHA standard requires that engineering controls
