Pseudomonas Bacterial Spot is a disease that causes spots on leaves and yellowing of leaves that eventually can drop off. As many other foliar disease, defoliation increase the risk for sun scald of fruit and lessens overall plant productivity
As nature begins to awaken from its winter slumber, those looking to identify backyard Iowa trees can consult a new video resource from Iowa State University Extension and Outreach forestry specialist Billy Beck. This series of five videos can be found on YouTube, or through the Iowa State University Extension and Outreach video website.
Alfalfa growth and development is affected by many factors, including temperature, soil moisture, stand age and even cultivar. Alfalfa growth has been slow this spring due to cooler than normal weather. This is a reminder that using the calendar date to determine when to harvest the first crop of alfalfa may not be the best method. In order to accurately predict the optimal time for the first cutting, the University of Wisconsin developed the Predictive Equations for Alfalfa Quality (PEAQ) method.
Items moving on and off your farm or ranch can bring disease. Recognizing movement risks can help you prevent them. The Livestock Project has created a Step 1: Movement risks checklist that can help you recognize and think about the types of movements that happen on your operation. In addition, the checklist can help you take the necessary steps to make those movements as safe as possible. The movements themselves and how often they occur are the key ideas to keep in mind. Major categories of movement risks are – animals and animal products, vehicles and equipment, visitors and personnel, and wildlife and pests.
Every five years, the U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) conducts the Census of Agriculture. The goal is to get a complete count of U.S. farms and ranches and the people who operate them. Information collected includes land use and ownership, operator characteristics, production practices, income, and expenditures.
The main focus of our three-state (Iowa, Kentucky, and New York), three-year (2020-2022) project is on finding better ways to manage diseases, insect pests, and weeds in organic systems, and getting that information to growers. Our funding comes from USDA’s Organic Research and Extension Initiative (OREI).
The Intelligent Sprayer is the creation of a team of USDA-ARS engineers at Wooster, Ohio, led by Dr. Heping Zhu. It has been tested on nursery trees, peaches, grapes, and other large-canopy crops, and is now available commercially for retrofitting standard airblast sprayers. Our study is the first to evaluate the Intelligent Sprayer for control of the full range of pests and diseases on apples during the whole growing season.
With summer in full gear it is a good time to evaluate how your fly control program is working. When horn fly numbers are greater than 200 flies per animal we see significant production losses associated with blood loss and decreased feed consumption. Numbers of face flies and stable flies are harder to assess because they only spend a small amount of time feeding on cattle but are still significant pests.
Multiple days of excessive heat can be hard on vegetable crops, especially ones known to be cool-season. Brassicas, lettuce, carrots and spinach are particularly vulnerable to bitterness, wilting, bolting, deformities and coloring that affect the quality of the produce.
