biological control of root-knot nematode (meloidogyne javanica) by pseudomonas fluorescens cha0 and trichoderma harzianum bi in tomato
root-knot nematodes (meloidogyne spp.) are among the most important groups of plant-parasitic nematodes, causing damage and yield losses to most cultivated plants. the bacterium pseudomonas fluorescens cha0 and the fungus trichoderma harzianum bi were investigated for biological control capability and systemic induction of resistance against the nematode m. javanica under glasshouse conditions....
متن کاملplant debris of oak forest as soil amendment, to improve the biocontrol activity of pseudomonas fluorescens and trichoderma vierns against meloidogyne javanica, in tomato
application of antagonistic agents in the rhizosphere of plants is an important approach in control of soil-borne pathogens. establishment and persistence of biocontrol agents in the soil is a major concern in biological control. this study aimed to determine the effect of plant debris of oak forests on activity of pseudomonas fluorescens and trichoderma vierns against meloidogyne javanica in t...
متن کاملExtracellular protease of Pseudomonas fluorescens CHA0, a biocontrol factor with activity against the root-knot nematode Meloidogyne incognita.
In Pseudomonas fluorescens CHA0, mutation of the GacA-controlled aprA gene (encoding the major extracellular protease) or the gacA regulatory gene resulted in reduced biocontrol activity against the root-knot nematode Meloidogyne incognita during tomato and soybean infection. Culture supernatants of strain CHA0 inhibited egg hatching and induced mortality of M. incognita juveniles more strongly...
متن کاملاثر تلفیقی قارچ Metarhizium anisopliae و باکتری Pseudomonas fluorescens CHA0 بر نماتود ریشهگرهی، Meloidogyne incognitaدر گوجهفرنگی
نماتود ریشهگرهی از مهم‌ترین نماتودهای انگل گیاهی با دامنه وسیع میزبانی است. با توجه به خطرات سموم، استفاده از روش‌های غیرشیمیایی، از جمله مهار زیستی در مبارزه با آفات و بیماری‌های گیاهی ضروری به نظر می‌رسد. در این پژوهش، اثر دو عامل کنترل زیستی Metarhizium anisopliae و Pseudomonas fluorescens CHA0 بر نماتود Meloidogyne incognita به طور جداگانه و به طور توام، در چند ...
متن کاملstudy on biological control and systemic induction of peroxidase enzyme activity in tomato plant infected with root-knot nematode (meloidogyne javanica) by pseudomonas fluorescens cha0 antagonist
biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...
