Postharvest diseases cause huge postharvest losses of horticultural fresh produce. Cooling and synthetic fungicide are used as traditional preservation technology. Recently, induced resistance has been thought to be an optional perhaps alternative 1-methylcyclopropylene (1-MCP) salicylic acid (SA) two more common chemical agents mostly a preservative for harvested fruit in order achieve better ...

One robust result from many small-scale experiments has been that plant community productivity often increases with increasing plant diversity. Most frequently, resource-based or competitive interactions are thought to drive this positive diversity-productivity relationship. Here, we ask whether suppression of plant productivity by soil fungal pathogens might also drive a positive diversity-pro...

In three field trials fungicides used for stem rust (Puccinia graminis) control were evaluated to assess the effect on levels of blind seed disease, seed germination and endophyte (Neotyphodium lolii) transmission. Blind seed disease infection was reduced from 24% to 5% in one of the three trials undertaken and germination was increased by between 17 and 23% in two trials. There was a negative ...

Quinone outside inhibitors (QoI) fungicides group were introduced for commercial use against apple scab (Venturia inaequalis) in Israel 1997. Unlike other regions the world, which resistance of V. inaequalis to QoI was observed within 3–5 years use, it only occurred after 14 use. Field trials conducted between 2007 and 2017 showed a significant reduction susceptibility QoIs northern since 2011....

Fungal Lipids, Ergosterol, Inhibition, Etaconazole, Fungicide The triazole fungicide etaconazole (C G A 64 251) interferes with the ergosterol biosynthesis in Ustilago maydis by inhibiting the C-14 demethylation o f the sterol nucleus. During the late log growth phase o f U. maydis a novel endogenous sterol metabolite (14x-methyl-ergosta-8,24(28)dien-3/?,6a-diol) was discovered and analyzed, wh...

rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...

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...

The novel agricultural fungicide 3-[5-(4-chlorophenyl)-2,3-dimethyl-3-isoxazolidinyl] pyridine (SYP-Z048) developed by China Shenyang Research Institute of Chemical Industry has been confirmed to be an ergosterol biosynthesis inhibitor (EBI). Previous studies have shown that EBIs target the proteins from a range of genes, including CYP51, ERG2 and/or ERG24, and ERG27, which are involved in the ...

In this study, we evaluated the activity of short antimicrobial peptides against different fungal isolates that cause postharvest decay of fresh fruits. The previously identified hexapeptides PAF19, PAF26 and LfcinB4-9 inhibited the in vitro growth of isolates from Penicillium digitatum and P. italicum, and from Alternaria and Geotrichum genera, being no active against Rhizopus, Mucor and Asper...
