Disease and Pests Management

by Paul Sachs

Both milky spore disease and beneficial nematodes help control grubs in lawn and garden. Depending on the species of grub, you may want to use both.

Scarab grubs, the broad group of white grubs that feed on grass roots, are difficult to differentiate. The only sure way to identify one positively is to look at the raster pattern on its rear end. Continue reading

El Departamento de recursos agrícolas de Massachusetts les solicita a todos a chequear los árboles para los indicios de plagas invasivas forestales. Insectos que matan a los árboles, tales como el Escarabajo asiático de antenas largas y (ALB por su sigla en inglés) el Barrenador esmeralda del fresno (EAB por su sigla en inglés), son una amenaza grave a los ecosistemas forestales a través de Massachusetts.

A plant disease commonly known as sudden oak death is killing trees in the coastal forests of western North America and portions of the United Kingdom and is an emerging threat in other areas. The disease is caused by the exotic, quarantine pathogen Phytophthora ramorum. While sudden oak death has killed a million tanoak and oak trees in California alone, numerous other species are susceptible to a non-fatal disease caused by the same pathogen. Called Ramorum blight, its hosts include many common garden plants. These plants serve as sources for inoculum that facilitate pathogen spread around the world. Continue reading

Richard Casagrande, Professor of Entomology at the University of Rhode Island lectured on August 2, 2012 at Massachusetts Horticulture Society on “Biological Control of Invasives.” He covered the efforts underway by scientists in the Northeast to use biological methods to control invasive plants and insects so that chemical pesticides and herbicides do not have to be used. Professor Casagrande provided a research update in August 2013. Continue reading

Eradicating ALB: The Threat of the Asian Longhorned Beetle

alb.240Thirty thousand of something is a difficult number to imagine. It’s even more staggering to envision 30,000 trees disappearing, but that is how many hardwood trees have been lost so far to the Asian Longhorned Beetle in the greater Worcester, MA, area. Asian Longhorned Beetle (“ALB”, scientific name Anoplophora glabripennis) is an invasive pest that was discovered in Worcester in 2008. It causes damage by tunneling deep into live trees, destroying them from the inside out. That makes this invasive insect a threat to hardwood trees throughout the state, and one that could have a serious negative impact on fall foliage tourism, the maple sugaring industry, and other forest product industries.
