Gummosis and psorosis are destructive bark diseases of Citrus trees found in ttliany groves throughout the state and of such widespread occurrence in certain sections as to cause considerable alarm on the part of growers. Many growers term the disease gummosis when there is a pronounced exudation of gum and scaly bark when there is a dry scaling off of the outer bark without much gum formation....

Lasiodiplodia theobromae is a causal agent of peach (Prunus persica L.) tree gummosis, a serious disease affecting peach cultivation and production. However, the molecular mechanism underlying the pathogenesis remains unclear. RNA-Seq was performed to investigate gene expression in peach shoots inoculated or mock-inoculated with L. theobromae. A total of 20772 genes were detected in eight sampl...

The gummosis disease is caused by Botryosphaeria dothidea (Moug. ex. Fr) Ces. et de Not., and it is one of the most important diseases of stone fruits worldwide. The use of biocontrol as an alternative approach to synthetic chemical fungicides has aroused general concern about how to control plant diseases that are caused by phytopathogens. The aim of this study is to isolate Bacillus strains f...

Young Valencia orange trees were grown for three years in large outdoor sand cultures on complete nutrient solu tions that varied differentially only in the amount of boron. Three rates of boron were applied to single-tree plots. The plots were replicated four times. No difference in tree size resulted from the differential treatments. Rather large differences in the boron content of the leaves...

To investigate the relationship between mineral elements and plum gummosis disease, Prunus salicina Lindl. trees with four grades of were used as experimental materials. The contents N, P, K, Ca, Mg, B, Fe, Mn, Zn Cu in branches leaves measured, correlation was systemically analyzed through multiple comparisons, binary logistic regression analysis, ordinal analysis. In addition, effects prevent...

Abstract Background Foot rot/gummosis of citrus, caused by Phytophthora spp., is the most important disease responsible for yield losses 10 to 30% in fruit production major citrus growing countries. Considering burden disease, present study was undertaken evaluate different native potent strains Trichoderma spp. against foot citrus. Results Based on molecular characteristics, i.e., ITS ribosoma...
