This happens because whiteflies often develop resistance to pesticides and pesticides often kill the natural predators that were helping keep the whiteflies in check. What you need to do is back off from the stronger pesticides, let the natural predators build back up and use gentler chemicals to cut back the whitefly population to a point where the predators -- such as lacewings, minute pirate bugs, big-eyed bugs, lady beetles and parasitic wasps -- can take over. What you need to do is...

Beekeepers at first attributed the losses to bee mites or viruses, ailments in the industry to which they had grown accustomed. Advertisement pollination contributes about $55 million to the value of Pennsylvania crops. Local beekeepers send their bees off, hives and all, on semi trucks to other states to pollinate crops there in Pennsylvania's non-growing seasons.

In recent years, the popularity of glyphosate-tolerant systems stymied chemical companies from developing new herbicides. Status, a tank-mix partner with glyphosate, can be used in both Roundup Ready acres and as a stand alone for broadleaf weed control on conventional corn acres, say BASF officials. However, the specter of glyphosate-resistant weeds is snapping new life back into the agricultural herbicide market. It combines broadleaf control similar to Callisto with improved grass...

State agriculture officials can hire legions of inspectors, and the Legislature can write volumes of new laws, but the abuse of pesticides will remain a threat to farmworkers and consumers until growers improve their record-keeping. Judge Stevenson said he could neither sustain the complaints nor absolve Ag-Mart because the company's records left him unable to tell whether rules were broken. The company appealed, and a judge dismissed more than two-thirds of the charges because the records...

KITTERY, Maine "" There may still be snow on the ground, but area communities are hoping local residents will start thinking now about grooming their lawns. The program's main focus is to encourage residents to forgo the chemicals and instead use gardening techniques that will grow a healthier lawn. Also, grass tends to become hearty and more resistant to crab grass and pests if maintained at three inches, about the length of a credit card. Reinehart, the project engineer who is putting...

Then as it got cold and icy, I received an equal number of calls from Carroll County residents concerned about the cold snap and its impact on their plants or possible ramifications for future insect pests. If you must fertilize in the spring, use no more than a half-pound of nitrogen per 1,000 square feet and use a fertilizer that contains at least 40 percent water insoluble nitrogen or slow-release nitrogen.
