RevisedThis publication provides information on pulse width modulation (PWM) technology including its working principle, components, benefits, and best management practices for its optimal utilization on agricultural sprayers. Pulse width modulation technology was developed to overcome pressure variation issues, as the flow rate is varied by changing the cycle of the electronically actuated solenoid valves while the system pressure remains constant throughout the boom.

NewGeorgia plant disease losses in 2024, including control costs, amounted to an estimated $860.12 million. The value of the crops used in this estimate was approximately $7,772.59 million, resulting in a 11.07% 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 & Economic Development 2024 Georgia Farm Gate Value Report (AR-26-01). Some crop value estimates were adjusted based on Extension specialists’ knowledge of the industry and industry sources for information.

Prevalence of mastitis in unbred, breeding-age and pregnant dairy heifers is higher than formerly realized. Infected mammary quarters 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. 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.
