Stinger has been labeled for weed control orchards for years, and now has a label for use in blueberries. The weeds controlled fall into two botanical plant families, composites and legumes. Common composite weeds found in our orchards include Canada thistle and other thistles, goldenrod species, aster species, common dandelion, mugwort (wild chrysanthemum), horseweed (marestail […]

Casoron will control most annual broadleaf weeds and suppress or control many perennial broadleaf weeds in cranberries, including redroot. Apply Casoron 4G to cranberry bogs after the winter flood has been removed, but before the vines break winter dormancy and begin to grow.
Continue reading...PPO-herbicides (Group 14) used in this area include Sharpen, Valor, Authority, Reflex, Blazer, Cobra, Aim, and Cadet. In addition to the single active ingredients, there are a number of premixes containing these PPO herbicides. This group is quite varied so making generalizations about these herbicides is difficult. PPOs have gained popularity in the past few […]
Continue reading...Last fall we collected seed from Palmer amaranth plants in Delaware and Wicomico County, Maryland and tested them for resistant to both glyphosate or ALS-inhibiting herbicides (Group 2). A few of the samples tested positive for resistance to both glyphosate AND ALS-herbicide. We used Pursuit in the initial trials, but past experience indicates that these […]

In field evaluations, we demonstrated that yellow sticky traps baited with the blend of four aggregation pheromone components trapped significantly more cranberry weevil adults than un-baited controls. Development of pheromone-based monitoring lures is an important step toward spatially-precise management techniques that may lead to significant reduction in the use of pesticides targeted against cranberry weevil […]
Continue reading...We recorded 56-58°F temperatures from soils in various Central Jersey commercial vegetable fields on April 15 –Tax Day– just before the recent multi-day cold front rolled in. The good news is 56-58°F was higher than I anticipated. What do soil temperatures have to do with your early vegetable seedlings? Mean spring soil temperatures determine early […]
