In 2016, Georgia’s plant disease losses, including control costs, amounted to an estimated $821 million. The value of the crops used in this estimate was approximately $6,596 million, resulting in a 12.8% relative disease loss across all crops included in this summary. The estimated values for most crops used to compute these disease losses are summarized in the UGA Center for Agribusiness and Economic Development’s 2016 Georgia Farm Gate Value Report (AR-17-01). Some estimates for fruits, ornamentals, and turf rely on specialists’ knowledge of the industry and industry sources for information.

Citrus leafminer (Phyllocnistis citrella) is found in Georgia and states along the Gulf of Mexico. Leafminer damage to foliage can stunt the growth of young trees and make trees more susceptible to citrus canker where the pathogen is present. Mature trees can better tolerate the damage although heavy infestations may reduce production. This publication discusses the identification, chemical control, noninsecticidal control, and homeowner control options for citrus leafminers.

Due to cows’ universal exposure to manure, which contains E. coli and other gram-negative bacteria, as well as the requirement to maintain sec as low as possible, all cows should be vaccinated with one of the coliform vaccines available on the market. These vaccines have been proven to significantly reduce clinical coliform mastitis and have been shown to be profitable when incidence of clinical coliform mastitis exceeds 1% of milking cows.

Viticulture Management
This phenology-based viticulture management poster provides a reference for sound viticultural, disease, and insect management practices in a digestible format. Viticultural practices optimize vineyard health, profitability, and sustainability and improve crop quantity and quality. Like pest management, viticultural practices should be implemented in a timely fashion throughout the growing season to maximize practice efficiency and benefit gain. Disease control in grapes is critical, as grapes are susceptible to a wide range of pathogens. Implementing timely and adequate cultural practices will greatly help to suppress diseases.

This publication covers the basics of different weed control options including mechanical, chemical, and environmentally friendly practices. The material provides both consumers and small vegetable farm growers options for weed control in their gardens. Weeds compete for space, steal nutrients and water from crops, and can look unsightly in the home garden. In general, weeds are easier to prevent in the garden than to remove once they start growing. Luckily, gardeners have several possible methods to help in their war on weeds.

The grass lace bug, Leptodictya plana Heidemann (Hemiptera: Tingidae), has been recently reported as a pest of ornamental grasses in Georgia. It is closely related to, and resembles, the sugarcane lace bug, L. tabida (Herrich-Schaeffer). The lace bug thrives in warm, dry conditions, and the recent drought in the Southeastern U.S. may have contributed to the grass lace bug’s recent emergence as a significant pest. This publication provides information about how to identify and manage this pest problem.

Operating a chainsaw is inherently dangerous. Chainsaw cuts are always serious, but this is not the only hazard a saw operator faces. Saw operators are often struck by falling limbs and trunks as the tree moves during felling. Saw operators may fall off ladders or out of trees, or they may trip while moving through brush and uneven ground. Even when the tree is on the ground, danger lurks in wood under tension. Spring poles snap and logs roll unexpectedly. Personal protective equipment (PPE) saves lives every day. The Occupational Safety and Health Administration (OSHA) requires that saw operators wear the PPE described in this publication, including head protection, eye protection, ear protection, chainsaw chaps or pants, and suitable footwear.
