Ginseng root rot caused by Cylindrocarpon destructans is the most destructive disease of ginseng. Six different fungicides (thiophanate-methyl, benomyl, prochloraz, mancozeb, azoxystrobin, and iprodione) were selected to evaluate the inhibitory effect on the mycelial growth and conidial germination of C. destructans isolates. Benomyl and prochloraz were found to be the most effective fungicides...

Abstract The aim of the study was to test in vitro and vivo efficacy triazoles biocontrol agents (BCAs) against Fusarium proliferatum F. oxysporum , former signaled as main causal agent garlic dry rot latter also involved. In trials were organized using potato dextrose agar with added chemicals or BCAs inoculated selected . Garlic cloves dipped before sowing suspensions prepared fungicides show...

Environ.Entomol.13: 1010-1014 (1984) ABSTRACT Field experiments were carried out to determine if a copper-based fungicide known to deter feeding by the Colorado potato beetle, Leptinotarsa decemlineata (Say), in the laboratory, could suppress the growth of L. decemlineata populations in the field when used regularly for plant disease protection on tomatoes, potatoes, and eggplants. Larval densi...

Essential oils can inhibit growth of several phytopathogenic fungi agricultural concern, such as Sclerotium spp. which causes root and collar rots, hampering the absorption water nutrients. Natural have short persistence in environment low toxicity, comprising compounds safer than conventional agrochemicals. Within context integrated management diseases, essential may benefit health farmers, co...

The in vitro and growth chamber, tests were conducted order to assess the effects of B. amyloliquefaciens B18 subtilis S8 strains each alone combination with tebuconazole against F. culmorum (FC) isolate responsible Fusarium crown rot (FCR) durum wheat. was unaffected by 30 µg.mL-1 tebuconazole. Bacillus (at 106 CFU.mL-1) tebuconazole, alone, reduced mycelial growth, this effect significantly i...

Fifteen fungal and three bacterial biological control agents (F-BCA B-BCA, respectively) were isolated from the canola production areas of Western Australia to investigate their potential for controlling sclerotinia stem rot (SSR) caused by Sclerotinia sclerotiorum under in vitro field conditions. The capacity these isolates inhibit mycelial growth sclerotia formation S. was assessed dual cultu...

Phytophthora infestans (P. infestans) is the causal agent of potato late blight, which caused the devastating Irish Potato Famine during 1845-1852. Until now, potato late blight is still the most serious threat to potato growth and has caused significant economic losses worldwide. Melatonin can induce plant innate immunity against pathogen infection, but the direct effects of melatonin on plant...

The antagonistic potential of culture filtrates of a soil isolate of T. viride was evaluated invitro, against three common post-harvest rot pathogens; A. niger, A. flavus, and F. oxysporum. Assay of three extracellular enzymes; chitinase, protease and cellulase, in respective enzyme-induced culture filtrates revealed the presence of enzyme activity. When 10% (v/v) concentration of the various l...

In in vitro tests with 18 plant pathogens, the fungicide 3-[5-(4-chlorophenyl)-2,3-dimethyl-3-isoxazolidinyl] pyridine (SYP-Z048) was highly effective on inhibiting mycelial growth of various ascomycota and basidiomycota, with EC50 values ranging from 0.008 to 1.140 μg/ml. SYP-Z048 had much weaker activity against growth of oomycota with EC50 values > 100 μg/ml. In a second in vitro test with M...
