As fall approaches, homeowners and green industry professionals take steps to prepare landscapes for the winter. Leaves are swept away for composting or disposal, perennials are cut back, trees and shrubs are pruned, hedges are trimmed and pesticides are applied in anticipation of next year's growing season.

For professional arborists and landscapers, fall and early winter are an effective time to use pesticides, a broad term that includes products that kill insect pests and also kill weeds (herbicides).

Insect Pests

"Many people don't have to use pesticides at all," says Peter Gerstenberger, senior advisor for safety, standards and compliance for the Tree Care Industry Association. "Professionals may be able to solve landscape problems without pesticides by choosing non-chemical alternatives, such as sanitation procedures and selecting shrubs and ornamental trees that are less susceptible to disease and insects.

"For example, an infestation last year may only require all the old plant material be cut our," notes Gerstenberger. "Often, cultural practices (pruning, raking leaves, etc.) will go a long way toward solving pest problems."… read more


NJ Department of Agriculture

New Jersey Secretary of Agriculture Douglas H. Fisher announced the New Jersey Department of Agriculture and United States Department of Agriculture personnel confirmed the sighting of the Spotted Lanternfly in northern Mercer County in New Jersey earlier this month. There were two confirmed sightings in southern Warren County earlier this summer. The specific areas where the spotted Lanternfly has been identified have been treated.

The sightings have led the State Department of Agriculture to quarantine the two affected counties as well as Hunterdon County, which is between Warren and Mercer counties, to prevent the spread of the Spotted Lanternfly.

"The Spotted Lanternfly is an excellent hitchhiker, with the ability to travel on all types of vehicles as well as various landscaping, wood-based materials and agricultural produce," Fisher said. "It's imperative that we stop the movement of this pest before it can make an impact on New Jersey."

Businesses and the general public in the quarantine area are required to obtain and fill out a New Jersey residence checklist before moving any of the articles listed at the end of this article. The checklist also serves to inform the public about the Spotted Lanternfly including how to identify all life stages of the insect and minimize or eliminate its movement.… read more

Today there are at least 120 important drugs derived from plants in use in one or more countries in the world. Discover some of the common drugs and medications which are derived from plants.


Caffeine is found in multiple plants and is used in many medicinal and everyday products. According to Chinese legend, the Chinese emperor Shennong discoverd the curative powers of caffeine when he realized dropping tea leaves into boiling water created a restorative drink in around 3000 BCE. Kola nuts were traditionally chewed in West African cultures to reduce the feeling of hunger and increase energy. Cacao pod residue was first found in an ancient Mayan pot, whilst chocolate derived from cacao beans was also used to create a spicy drink called xocolati which fought fatigue.

The first people to harvest coffee beans for their energizing properties were the Ethiopian ancestors of the Oromo people, but caffeine wasn't isolated from coffee beans until 1819 when a German chemist, Friedlieb Ferdinand Runge, researched the plant. Caffeine today is used to relieve the symptoms of a migraine, but most commonly is still enjoyed as an energizing ingredient in food and drinks.


Salicylic acid, which is a key component of aspirin, was first dscribed by the father of medicine, Hippocrates, who referred to a white powder derived from willow bark which alleviated the symptoms of aches, pains and fevers. In 1763, Edward Stone at Oxford was the first chemist to isolate the active ingredient and it has since been used in medicine both for its analgesic and anti-clotting properties.

There are many different varieties of willow tree and the bark of each carries a different potency of salicylic acid. Aspirin is created by a chemical reation between salicylic acid and acetic acid, which is the main component of vinegar, apart from water. … read more
