Weeds, Diseases and Pests
-
The diamondback moth is a common pest of crops including cabbage, collards, turnip greens, mustard greens, broccoli, cauliflower and other leafy greens.
This insect has a long history of becoming resistant to insecticides beginning with DDT in 1953. Since then, DBM has become resistant to each new class of insecticide arriving to the market whenever those insecticides were used intensively and repeatedly to control a DBM population.
Prevention is critical. To delay the onset of resistance follow the practices listed in this circular. Even if resistance is detected in an area, these tips can inhibit its spread and preserve insecticide effectiveness.

Weed management is one of the most critical and costly aspects for container nursery production. High irrigation and fertilization rates create a favorable environment for weed growth in addition to crop growth. Weeds can quickly out-compete the crop for light and other resources, reducing the rate and amount of crop growth as well as salability. Weed management in nursery production is most effectively achieved by preventative practices, primarily with the use of pre-emergent herbicides. However, there are valid reasons for managing weeds using alternatives to synthetic herbicides. Weed management alternatives to synthetic herbicides include sanitation, exclusion, prevention, hand weeding, mulching and use of cover crops, heat and non-synthetic herbicides. Only some of these alternative methods can be used to control weeds in containers, but all can be used to manage weeds around containers and in non-crop
areas.|

Even with today’s technology, it is critical that growers use directed herbicides in their cotton crop to improve coverage of weeds hiding under the cotton canopy. Precision applications maximizing spray coverage of weeds and minimizing spray contact with cotton, which can cause injury, is critical. Spray fender/cultivator and shield/hood sprayers are commonly used for precision, directed-spray applications.

If deer are overabundant in your neighborhood, and deer herd reduction or management is not feasible, a good way to prevent deer browsing in landscapes is to plant ornamental plants that deer do not like to eat.

It is estimated that 2013 plant disease losses, including control costs, amounted to approximately $821.85 million. The value of the crops used in this estimate was approximately $6,551.91 million, resulting in a 12.55% total disease loss across all crops included in this summary.
Loss estimates for apple, blackberry, blueberry, bunch grape, corn, cotton, muscadine grape, ornamentals, peach, peanut, pecan, soybean, strawberry, turfgrass, vegetables, and wheat in 2013 are presented in this report.

It is estimated that 2012 plant disease losses, including control costs, amounted to approximately $855.98 million. The value of the crops used in this estimate was approximately $6,647.83 million, resulting in a 12.9% total disease loss across all crops included in this summary.
Loss estimates for apple, blackberry, blueberry, bunch grape, corn, cotton, muscadine grape, ornamentals, peach, peanut, pecan, soybean, strawberry, turf grass, vegetables, and wheat in 2012 are presented in this report.
