Weeds, Diseases and Pests

It is estimated that 2011 plant disease losses, including control costs, amounted to approximately $823.4 million. The value of the crops used in this estimate was approximately $6285.1 million, resulting in a 13.1% total percent disease loss across all crops included in this summary.

Prevalence of mastitis in unbred, breeding-age and pregnant dairy heifers is higher than formerly realized. Infected
mammary quarters, especially those with Staph. aureus IMI, exhibit reduced mammary gland secretory
potential, marked leukocyte infiltration and the accompanying inflammation. Both nonlactating and lactating
commercial antibiotic infusion products have been used successfully to cure existing infections and reduce SCC,
and nonlactating therapy prevents new IMI with environmental streptococci. However, the goal is to prevent
new infections from occurring in these young dairy animals through management strategies aimed at vaccination,
use of teat seals, fly control and dietary supplementation. As global milk quality standards
become more stringent, management practices based on curing existing infections and preventing new IMI
in heifers will ensure that these young dairy animals enter the milking herd free of mastitis and with low SCC.
Such practices should be considered for incorporation into dairy herd health programs in herds suffering from a
high prevalence of heifer mastitis, especially mastitis caused by Staph. aureus. Not only do these practices reduce
new infections in first-calf heifers at parturition, they also reduce the introduction of Staph. aureus to the milking
herd.|

Peanut Response to Liberty
Liberty® (glufosinate-ammonium) has become a popular postemergence herbicide in Georgia due to its ability to control herbicide-resistant Palmer amaranth when applied in a timely manner. However, the popularity of Liberty®-resistant cultivars (e.g., Liberty-Link® and WideStrike®) has led to an increased potential for off-target movement and sprayer contamination of Liberty® to sensitive crops such as peanut. This publication describes symptoms of peanuts exposed to Liberty.

It is estimated that losses due to plant diseases in Georgia in 2008 amounted to $612.06 million. These losses include actual losses in yield and quality as well as costs of disease control measures. The value of these crops was approximately $4,846.05 million, which resulted in a 12.03% total disease loss for crops grown in 2008.

It is estimated that 2001 plant disease losses, including control costs, amounted to approximately $587.107 million. The value of the crops used in this estimate was more than $4.799 billion, resulting in a 12.23 percent total disease loss across all crops included in this summary.

It is estimated that 2000 plant disease losses, including control costs, amounted to approximately $572.34 million. The value of the crops used in this estimate was more than $4.376 billion, resulting in a 13.07 percent total disease loss across all crops included in this summary.

It is estimated that 1999 plant disease losses, including control costs, amounted to approximately $580.25 million. The value of the crops used in this estimate was $4.124 billion, resulting in a 14.07 percent total disease loss across all crops included in this summary.
