Whiteflies are common and recurrent insect pests of cotton in Georgia. The severity of whitefly damage varies from year to year based on the size of the pest population. The most abundant species of whitefly found infesting cotton in Georgia is Bemisia tabaci, commonly known as the silverleaf whitefly (SLWF) or sweet potato whitefly. Another species, bandedwinged whitefly (Trialeurodes abutiloneus), may also be present in Georgia cotton. This publication highlights whitefly biology, damage, sampling procedures, control methods, and tips for managing risk in cotton.

Detection of damaging nematode infestations may allow growers to significantly increase crop productivity and profitability. It is imperative that growers test their soil to determine which nematode species are present in their fields as well as their population densities. The best way to detect and identify nematode problems is through collecting soil and/or plant samples and having those samples analyzed in a reliable nematode diagnostic lab. It is highly recommended that, if you suspect a field has a nematode problem, test the soil and then consult with your local Extension agent or nematologist for advice on how to manage the nematode infection.

2021 plant disease losses, including control costs, amounted to an estimated $889 million. The value of the crops used in this estimate was approximately $7690 million, resulting in a 11.6% relative disease loss across all crops included in this summary. For most crops, the estimated values used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development’s “2021 Georgia Farm Gate Value Report” (AR-22-01). Some estimates for fruits, ornamentals, and turf rely on specialists’ knowledge of the industry and industry sources for information.

Los Arándanos y Su Producción
El arándano alto del sur, es un híbrido que requiere pocas horas de frio—una aproximación de cuantas horas la planta requiere estar expuesta a temperaturas de entre 32 a 45 °F para romper la dormancia y empezar iniciación floral—comparado con el arándano alto del norte. Por lo que permite al estado de Florida y áreas del Sur de Georgia posicionarse en el mercado estadounidense en los meses de Marzo, Abril y Mayo, y es el que ha permitido la producción de arándanos para exportación en países como México y Perú.
