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 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 کاملEfficacy of Different Bio Control Agents against Meloidogyne incognita and Fusarium oxysporum on Tomato
Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops grown in the world, next to potato. It is used as a fresh vegetable and also can be processed and canned as a paste, juice, sauce, powder or as a whole (Barone and Frusciante, 2007). The ripe fruits are good source of vitamin A, B and C which add wide varieties of colour and flavour to the food. Recently, it started gai...
متن کاملReaction of Trifolium repens Cultivars and Germplasms to Meloidogyne incognita.
Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...
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 ...
