This guide summarizes the insecticides/miticides registered in North Dakota for control of insect or mite pests of filed crops. Scouting and economic thresholds are listed for the major pest. Keeping in mind that chemical control is only part of an Integrated Pest Management approach. The most effective control may involve integrating culture, host plant resistance and other strategies.
Potato cultivars or selections included in this report were selected from recently released cultivars or from advancing selections or cultivars that are new to the United States. In 2019, two trials were conducted to identify traits of red-skinned and yellow-skinned potato cultivars and advanced selections at Hoople, N.D.
Potato cultivars or selections included in this report were selected from recently released cultivars, advancing selections with release potential (numbered lines progressing through the trial process), or cultivars that are new to the U.S. Standard potato cultivars used by growers served as checks. The agronomic data presented in Tables 1 and 2 were analyzed statistically. These analyses allow the reader to ascertain, at a predetermined level of confidence, if the differences observed among cultivars/selections are reliable, or if they might be due to error inherent in the experimental process.
Table summarizes the agronomic and milling and baking performance of hard red spring wheat varieties test in multiple locations in North Dakota in 2020. These data can be use to guide growers in selecting varieties with the performance and traits desired.
This publication provides summary tables for the performance of spring wheat varieties grown in several locations within the state of North Dakota.
Results of winter wheat trials conducted throughout the state are included in this publication. The result tables provide data that can be used to select winter wheat varieties that performed well in 2020.
Results of winter wheat trials conducted throughout the state are included in this publication. The result tables provide data that can be used to select winter wheat varieties that performed well in 2019.
Repeated use of herbicides with the same site of action alone can result in the development of herbicide-resistant weed populations.
The North Dakota Soybean Variety Trial Results and Selection guide provide producers with data on soybean performance throughout North Dakota and gives information about yield and other agronomic traits, for accurate selection of dry bean varieties for agricultural production in North Dakota.
The North Dakota Soybean Variety Trial Results provide producers with data on soybean performance throughout the state and gives information about yield and other information needed for accurate selection of soybean varieties for agricultural production in North Dakota.
The North Dakota Sunflower Trial Results provide producers with data about Hybrid performance through the state and gives information about yield and other information needed for accurate selection of sunflower hybrids for agricultural production in North Dakota.
The North Dakota Sunflower Hybrid Trial Results and Selection guide provide producers with data on sunflower performance throughout North Dakota and gives information about yield and other agronomic traits, for accurate selection of sunflower hybrids for agricultural production in North Dakota.
The term secondary growth is often described as heat sprouts, tuber chaining and tuber malformations. This physiological disorder decreases yield and quality of all potato tubers. Good management and varietal selection can minimize this.
The Pulse Crop Production Field Guide provides producers with data on field pea, chickpea and lentil production information throughout North Dakota. It addresses issues including variety fertilizing, disease, insect and weed control, harvesting and storing of pulses.
Provides general and management information on leaf, stem and stripe rust of wheat in North Dakota.
This publication provides background information on how to grow safflower in ND, from land selection, fertilizer management, variety selection, seeding, weed management to harvesting and marketing the crop. Safflower is an annual oilseed crop adapted primarily to the central grain areas of the western Great Plains.
Research from 2011 to 2013 has resulted in a data base that supports the use of active-optical sensors to direct side-dress N rate in corn. Previously, rates were determined using a grower's best guess.
This series aids in disease identification.
This publication describes two species of gall midges that infest soybeans. Soybean gall midge is an invasive and economic insect pest of soybeans that occurs in five Midwestern states (Iowa, Minnesota, Missouri, Nebraska and South Dakota). It does not occur in North Dakota yet. The white-mold gall midge is native to North America and is not economic insect pest of soybeans. Larvae of the white-mold gall midge can be found feeding on Sclerotinia white mold disease in stems and pods. This publication describes how to scout and identify the two species based on their location on plants, field symptoms and plant injury symptoms. It also tells pest managers what to do if you find any suspect soybean gall midge in your soybean fields in North Dakota.
The North Dakota Soybean production field guide provide producers with data fo soybean production information throughout the state. It addresses issues from variety selection, growth and fertilizing, disease, insect and weed control, harvesting and storing of soybeans.
This publication summarizes the evaluation of data generated by NDSU soybean field trials conducted during 2008 through 2019 in North Dakota that included planting rates and row spacing.
All of NDSU soil fertility recommendations now have no yield-based formulas. The soybean fertility recommendations were modified to be in line with these new guidelines.
This publication provides an overview of the main growth stages of sunflower with pictures for clarification.
The sunflower production guide provides agricultural producers, consultants and others in the ag-industry with production information. There are sections about agronomy, insect, weed and disease management, harvesting, storage and marketing.
The timing of swathing canola is important for quality and yield. This publication provides information about the proper stage to swath canola and the effect of swathing time on yield, green seed and percent oil. A description is provided about how to set the swather and combine to optimize the yield and quality of canola.
Drainage pump stations are an expensive addition to a subsurface drainage project. This publication provides guidance on the design and location of drainage lift stations. This topic an be difficult to teach in typical Extension presentations, this publication provides more details.
Low pH or soil acidity affects nutrient availability, microbial activity as well as plant growth. This publication covers a definition of soil acidity, causes of soil acidity, effect on soil nutrients and crops, and how to identify this issue.
