The influence of Arbuscular mycorrhiza fungi (AMF) (Glomus deserticola and Gigaspora gigantea) were evaluated on drought tolerance and charcoal rot disease of cowpea genotypes: IT90K-277-2, IT84S-2246-4 and IT06K123-1. IT90K-277-2 and IT84S-2246-4 were sown in 3 kg of sterilized soil for drought experiment with five treatments. Treatment was established thirty days after germination with inocul...

Paulownia species are fast growing trees native to China, which being grown in managed plantings several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, collapse, as a consequence root crown rot, were observed around 40% 2-year-old planting elongata × P. fortunei Calabria (Southern Italy). Two Phytophthora consistently recovered from root...

Lasiodiplodia theobromae is a fungal pathogen associated with perennial tropical fruit plants worldwide. In citrus, L. causes stem-end rot (Diplodia rot), damaging postharvest disease that aggravated when trees are also infected the citrus greening bacteria ‘Candidatus Liberibacter asiaticus’. Due to latent infection of during preharvest stage, it becomes difficult control by chemical or physic...

Strip tillage with various crop covers in peanut (Arachis hypogaea, L.) production has not shown a clear yield advantage over conventional tillage, but has been found to reduce yield losses from some diseases. This study was conducted to determine pod yield and disease incidence between two tillage practices, five winter cover crops, three peanut cultivars, and three fungicide programs. Convent...

The potentials of poultry, farmyard and refuse dump manures for management of Phytophthora root rot on sweet peppers, Capsicum annuum was evaluated in pot experiments under controlled conditions. Five week-old seedlings of pepper varieties were transplanted into heat sterilized soil amended with poultry, farmyard and refuse dump manures at 2, 4 and 8 tons/ha. The pots were arranged in complete ...

Soil-borne diseases are a significant cause of reduction in crop yield. Alternative management soils can enhance the natural disease-controlling organisms soil. This study explores impact alternative production methods on primary soybean disease, charcoal rot, caused by fungus Macrophomina phaseolina. Treatments that could potentially or control disease were implemented, and soil tests conducte...

pectobacterium carotovorum is one of the most important bacterial pathogens of potato in the world.the expression of numerous genes including those involved in the production of virulence determinants in this bacterium are regulated by quorum sensing (qs). the signal molecules involved in qs in p. carotovorum belong to the group of n-acyl homoserine lactones (ahls). recently, several soil bacte...

Charcoal rot (CR) disease caused by Macrophomina phaseolina is responsible for significant yield losses in soybean production. Among the methods available for controlling this disease, breeding for resistance is the most promising. Progress in breeding efforts has been slow due to the insufficient information available on the genetic mechanisms related to resistance. Genome-wide association stu...

Maximum colony growth inhibition was observed due to Pseudomonas PS2 (74%) as compared to PS1 (71%) on trypticase soy agar (TSM) plates after 5 days of incubation. Light and scanning electron microscopic examination showed hyphal coiling, vacuolation, coagulation and granulation of cytoplasm resulting in lysis of hyphae of M. phaseolina by pseudomonads. Cell free culture filtrates of strains PS...
