Each month Grow Monthly shares a selection of new and favorite webcasts that provide applied knowledge to practitioners, the Extension community, and those they serve. Formerly behind a paywall, these webcasts from crop protection experts are now freely available.
Featured Webcast

POLLINATORS HUB
The eastern North American migratory population of the monarch butterfly is in serious decline. Adam Baker explains how applying sustainable agriculture theory and butterfly host-finding theory to conservation gardens can help monarchs and other pollinators. This hub also includes a summary webcast, study guide, and slide download.

FOCUS ON CORN 
Soil water-monitoring equipment can determine how much water crops remove from soil. William Kranz explains how to use a modified atmometer to verify that soil water sensors are responding correctly and discusses several water conservation practices.

FOCUS ON COTTON
By assessing crop vigor status and fruit load and using nodes to measure crop progression during the fruiting cycle, cotton growers can make more informed crop management decisions. Randy Norton provides specific examples of this relationship, touching on plant growth regulator applications and end-of-season cotton management techniques.

FOCUS ON CUCURBITS
Common in the southeastern and eastern United States, downy mildew of cucurbits can cause significant yield loss. Rebecca Melanson discusses characteristics of the pathogen; symptoms and signs of disease; and disease detection, identification, and management.

FOCUS ON POTATO
Recent weather patterns have resulted in greater water usage, making mid- to late-season irrigation practices more complicated. Howard Neibling provides suggestions for in-season equipment modification and additional water management options to obtain the highest yield and quality of potatoes with less-than-adequate water.

FOCUS ON SOYBEAN
Some irrigation techniques can increase yield while maintaining or reducing current water usage. Learn more about these techniques in this presentation by Trey Koger, who also discusses irrigation timing specifically for soybeans in the mid-South.

FOCUS ON TOMATO
Great care must be taken in delivering nutrients to tomato plants and ensuring they have sufficient moisture for nutrient uptake and utilization. Josh Freeman explains how growers can give their tomato crops the right amount of nutrients in the right place at the right time.

FOCUS ON WHEAT
Why are we concerned about wheat streak mosaic? What factors contribute to the development of disease outbreaks, and what can we do to reduce the risk of severe yield losses? Learn more in this presentation by Erick De Wolf.

SURVEY
Until recently, the last reported incidence of citrus canker in Texas was in 1943. However, Perez et al. report that the disease appeared again in 2016. The Texas Department of Agriculture collected nearly 2,000 positive strain samples from Harris, Fort Bend, and Brazoria Counties and is currently removing positive trees and continuing surveys.

NOTABLE RESEARCH
Fusarium head blight lowers yield and contaminates wheat and barley with mycotoxins such as deoxynivalenol, which are controlled by applying triazole fungicides at the anthesis or flowering stage, a small window that is easy to miss. Singh et al. tested the efficacy of a new fungicide called Miravis Ace and found that application at 50% head emergence provided significant control.
