Cucumber Fusarium wilt, induced by Fusarium oxysporum f. sp. cucumerinum (FOC), causes severe losses in cucumber yield and quality. Nitrogen (N), as the most important mineral nutrient for plants, plays a critical role in plant-pathogen interactions. Hydroponic assays were conducted to investigate the effects of different N forms (NH₄⁺ vs. NO₃‒) and supply levels (low, 1 mM; high, 5 mM) on cucu...

Four bean genotypes (IPA-1, A-107, A-211, and Calima), representing all possible combinations of resistance and susceptibility to Fusarium oxysporum f. sp. phaseoli (Fop) and Meloidogyne incognita, were each inoculated with three population densities of these pathogens. Calima and A-107 were resistant to Fop; A-107 and A-211 were resistant to M. incognita; and IPA-1 was susceptible to both path...

The use of novel isolates of Trichoderma with efficient antagonistic capacity against Fusarium oxysporum f. sp. lycopersici (FOL) is a promising alternative strategy to pesticides for tomato wilt management. We evaluated the antagonistic activity of 30 isolates of T. asperellum against 4 different isolates of FOL. The production of extracellular cell wall degrading enzymes of the antagonistic i...

Fusarium oxysporum f. sp. ciceri and Meloidogyne javanica are important pathogens of chickpea. Interrelationships between Fusarium oxysporum f. sp. ciceri and M. javanica were investigated on 53 Fusarium wilt-resistant chickpea genotypes in pot experiments. All of the genotypes were susceptible to M. javanica. Fusarium wilt resistance in one genotype (ICC 12275) was ineffective in the presence ...

A trial was conducted to suppress bacterial wilt of tomato (BWT) caused by Ralstonia solanacearum using biocontrol agents (BCAs) isolated from soils in Kalimantan, Indonesia. Five isolates were selected from 270 isolates as better performing BCAs through screening four times using a pumice medium. The isolates selected were identified as Burkholderia nodosa, Burkholderia sacchari, Burkholderia ...

Alcaligenes xylosoxydans protected pigeonpea from Fusarium wilt in a pot experiment and field trials. When seeds of pigeonpea (C. cajan) were treated with A. xylosoxydans and sown in soil infested with Fusarium, the incidence of wilt was reduced by 43.5% and resulted in 58% higher grain yield. The antifungal activity of A. xylosoxydans was based on chitinase production and was comparable in eff...

Tomato Fusarium wilt caused by oxysporum f.sp. lycopersici (Fol) constrains tomato production worldwide. Three hundred forty accessions were evaluated for resistance and single nucleotide polymorphisms (SNPs) associated with resistance. The disease evaluation revealed that 15, 13, 15 identified as resistant in Test 1, 2, Mean data, respectively, the severity index (DSI) ranging from 0-16.7%. A ...

ABSTRACT Fusarium oxysporum f. sp. ciceris and the root-lesion nematode Pratylenchus thornei coinfect chickpeas in southern Spain. The influence of root infection by P. thornei on the reaction of Fusarium wilt-susceptible (CPS 1 and PV 61) and wilt-resistant (UC 27) chickpea cultivars to F. oxysporum f. sp. ciceris race 5 was investigated under controlled and field conditions. Severity of Fusar...

Zhao Q., Mei X., Xu Y. (2016): Isolation and identification of antifungal compounds produced by Bacillus Y-IVI for suppressing Fusarium wilt of muskmelon. Plant Protect. Sci., 52: 167–175. The Bacillus strain Y-IVI was used in the biocontrol of muskmelon Fusarium wilt. It was identified as Bacillus subtilis . The antifungal compounds from the culture filtrate were purified by high performance l...
