Antracnose é uma das doenças economicamente mais importantes da soja e de difícil controle no Mato Grosso, causando perdas significativas produtividade. Objetivo foi verificar a sensibilidade fungicidas reação cultivares 30 isolados Colletotrichum. A ação sete (azoxistrobina + ciproconazol, piraclostrobina epoxiconazol, trifloxistrobina protioconazol, piraclostrobina, carbendazim, fluxpiroxada ...

Early blight (EB), caused by fungi Alternaria solani and A. tomatophila, is a major foliar disease of the tomato in many growing regions. Sources of resistance have been identified within the related wild species of tomato, including S. habrochaites, S. peruvianum and S. pimpinellifolium. Breeding for EB resistance via traditional protocols has been difficult due to the complexity of resistance...

Suppressive composts represent a sustainable approach to combat soilborne plant pathogens and an alternative to the ineffective chemical fungicides used against those. Nevertheless, suppressiveness to plant pathogens and reliability of composts are often inconsistent with unpredictable effects. While suppressiveness is usually attributed to the compost's microorganisms, the mechanisms governing...

Methods for rapid inbreeding are desirable for reducing the time required to complete a breeding cycle and to increase genetic gain per year. Constitutive expression of FLOWERING LOCUS T (FT ) derived from Arabidopsis has previously been shown to reduce generation time in tobacco (Nicotiana tabacum L.) and other crop plants. Here, we used tobacco as a model system to investigate the utility of ...

Early blight (EB), caused by the necrotrophic pathogen Alternaria solani, is one of most common and destructive diseases in tomato (Solanum lycopersicum L.). The use fungicides a prominent tactic used to control EB; however, their undesirable effects on environment human health, as well involvement development resistant strains, have driven researchers search for new alternatives. Plant defense...

Vascular wilt, caused by the infection of soil-borne pathogen Fusarium oxysporum (Fo), is one most destructive diseases many crops, including legumes such as grass pea (Lathyrus sativus), with several formae speciales (ff. spp.) defined according to their hosts. Commonly described host-specific, Fo could, in some cases, show a broader host range comprising related plant species, making its char...

The efficacy of traditional control measures for the management plant pathogens is decreasing, and resistance these to pesticides increasing, which poses a serious threat global food security. exploration novel efficient combat disease an urgent need at this time. In study, fungal metabolites from three Trichoderma spp. (T. harzianum, T. virens koningii) were prepared on different growth media ...

background and objectives: septoria leaf blotch disease (stb) caused by the fungus mycosphaerella graminicola (fuckel) j. schroeter (anamorph: septoria tritici roberge), is one of the most destructive foliar diseases of wheat in the world, that its worldwide damage in outburst years is about 30 to 50 per cent. the pathogen is a bipolar heterotallic ascomycete that its sexual life cycle is repea...
