Detection of Possible Phytophthora pinifolia Infection in Pinus radiata Green Sawn Timber Produced in Chile
A new needle blight disease was observed on Pinus radiata in Chile during 2004. The disease, known in Chile as Daño Foliar del Pino (DFP), stretches southward from the Arauco to Valdivia Provinces, and was present over an area of about 60 000 ha in 2006, with different levels of intensity. The disease is typified by needle infections and exudation of resin at the bases of the needle brachyblast...
متن کاملBiocontrol of Fusarium circinatum Infection of Young Pinus radiata Trees
Pitch canker, caused by the fungus Fusarium circinatum, is a major disease of Pinus radiata currently controlled to some extent in nurseries by good hygiene and application of synthetic fungicides. The aim of this study was to evaluate alternative strategies to control fungal infections in nurseries and young pine plantations. The antagonistic effects of biocontrol bacteria and essential oils a...
متن کاملAssessing the Health of Pinus Radiata Plantations Using Remote Sensing Data and Decision Tree Analysis
Forest health monitoring is essential to sustainable management of Pinus radiata D. Don plantations. Conventional survey techniques such as aerial sketch mapping are qualitative and subjective, their effectiveness depending on the skill of the surveyor. In contrast, digital remote sensing has the potential to provide quantitative and objective data on the location, extent, and severity of crown...
متن کاملGrowth and water use of Eucalyptus grandis and Pinus radiata plantations irrigated with effluent.
We studied the growth and water balance of young plantations of Pinus radiata D. Don and Eucalyptus grandis W. Hill ex Maiden irrigated with effluent for 3 years in a climate of high net evaporation. The plantations were irrigated weekly with secondary-treated municipal effluent at the estimated water-use rate, or at nominally twice or half this rate. Control plots were irrigated with bore wate...
متن کاملThe Abortion of Conelets in Pinus Radiata
Observations and records collected over a six-year period show that, in a seed orchard of Pinus radiata at Kaingaroa Forest, approximately half of all female strobili initiated abort during the first year after pollination. For an average clone this process of conelet drop starts at the time of receptivity, reaches a peak some four to six weeks later, and then decreases in intensity. This time ...
