A nodule-inhabiting
Abstract Thaumastocoris peregrinus Carpintero & Dellapé (Heteroptera: Thaumastocoridae) is a sap‐sucking insect that feeds on leaves of Eucalyptus. In Uruguay, it was detected in 2008 causing significant economic losses Eucalyptus plantations. At present, there no efficient control for this pest; thus, the use biological agents seems to be an environmentally friendly alternative reduce damage caused by insect. The aims study were isolate and identify species entomopathogenic fungi...
Grain mold and stalk rot are among the fungal diseases that cause significant losses in sorghum worldwide caused by different Fusarium spp. The presence of species grains causes yield mycotoxin contamination, which represents a risk to consumers. In this study, graminearum complex (FGSC) had high incidence, followed fujikuroi (FFSC) F. incarnatum-equiseti complex. Within FFSC, proliferatum, andiyazi, fujikuroi, thapsinum, verticillioides subglutinans were identified, was first report...
Abstract Background The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae) is an insect pest species responsible for damages of fruit quality and tree health. This a vector bacteria ‘ Candidatus Liberibacter’ spp . putative causal agent greening disease known as Huanglongbing (HLB), considered one the most destructive diseases orchards worldwide. Disease management mainly based on control using pesticides which can affect natural enemies that play important role in...
The bronze bug Thaumastocoris peregrinus is an invasive pest, affecting Eucalyptus plantations worldwide. Although its natural enemy Cleruchoides noackae has been tested for the biological control of this other strategies like use native entomopathogenic fungi are needed. For this, virulent fungal isolates should be selected, massively multiplied in efficient way, and prepared to obtain a stable product. Isolates Beauveria bassiana obtained from T. different collections were screened their...
Uno de los principales problemas que afectan el cultivo sorgo (Sorghum bicolor) en Uruguay es la enfermedad ocasionada por Fusarium nygamai, responsable pérdidas rendimiento cultivos. Además, capaz producir micotoxinas como fumonicina, moniliformina y beauvericina, lo constituye un riesgo para alimentación animal. El objetivo este trabajo fue identificar cepas Trichoderma spp., con potencial control F. nygamai sorgo. Se identificaron dos asperellum, cinco atroviride, virens, una cepa...
Sorghum is the third major rainfed summer crop after maize and soybean in Uruguay. Worldwide this affected by Fusarium spp. that infect colonize panicles, kernels, peduncles, stalks, roots, causing yield losses threatening grain quality. In Uruguay, F. graminearum sensu stricto (F. s.s.) predominant species grain, followed proliferatum, andiyazi, fujikuroi, thapsinum, but little known about these country. To assess pathogenicity, a mixture of three isolates from each five were used to...
ABSTRACT A nodule-inhabiting Paenibacillus sp. strain (UY79) isolated from wild peanut ( Arachis villosa ) was screened for its antagonistic activity against diverse fungi and oomycetes Botrytis cinerea, Fusarium verticillioides, oxysporum, graminearum, semitectum, Macrophomina phaseolina, Phomopsis longicolla, Pythium ultimum, Phytophthora sojae, Rhizoctonia solani, Sclerotium rolfsii Trichoderma atroviride ). Results obtained show that UY79 able to antagonize these fungi/oomycetes...
