Recent impacts of APMC IPM Programs. Topics include savings to growers from thrips and Lygus resistant ThryvOn Cotton, a project to reduce use of the riskiest pesticides throughout US cotton, collaborations with tribal growers and communities to protect public health, and more.
Goss’s bacterial wilt and leaf blight
(Goss’s wilt) was first recorded in Nebraska in the late 1960s
and is now distributed widely in most states throughout
the Corn Belt. The disease was first detected on field corn
in southeastern Arizona in 2018.
Alternaria leaf spot of cotton is also known as Alternaria leaf blight. The disease was first identified in cotton in the US in 1918 and is now distributed worldwide. Alternaria leaf spot has been considered a minor disease in the cotton growing areas of Arizona.
Do Antimicrobial Water Sanitizers Affect Insecticide Efficacy in Desert Produce?
Food safety issues have become increasingly important in the production of leafy vegetables in the desert. Recent concerns about microbial contamination of produce grown in the desert prompted the Arizona Leafy Greens Marketing Agreement (AZLGMA) to develop new Food Safety Guidelines for lettuce and leafy greens.
The bagrada bug, Bagrada hilaris, became a major pest of cole crops in the fall of 2010 where widespread out breaks of the invasive stinkbug pest were reported throughout the desert SW. The resulting yield losses in broccoli, cauliflower, cabbage, and other Brassica crops were economically significant.
Weed Interference with Insect Management in Desert Crops 2020
Effective weed management is critical for the profitable production of vegetable crops in the desert southwest for all the obvious reasons. However, weed management is also essential for another important, but often overlooked reason.
Local weather patterns can have a significant impact on the abundance of insect pests in vegetable crops, particularly in the southwestern U.S. where weather extremes are the norm. Components of weather, mainly temperature, moisture, and wind can either promote insect population growth or cause populations to decline. As we approach the normal cool, dry weather of winter, growers can expect insect activity to decrease. Why is that?
2019 Guidelines for Diamondback Moth Management in Desert Cole Crops
List of Guidelines prepared in response to the diamondback moth (DBM) outbreaks that occurred in 2016-17 in Arizona. Following these guidelines can help keep the moths from spreading. There is also a list of insecticides and their respective efficacy against DBM.
In 2016 there was a outbreak of Diamondback Moths. This article covers a bit of the history of that outbreak and how the were handled in the next two years. The event was partially documented by some surveys found in this article.
