Large Seeded Bean Seeding Date and Seeding Rate Study

Growers plant beans earlier in regions with fewer crop heat units (CHU) to avoid losses from fall frost, but the Ontario growing season is getting longer. Bean market classes grown, plant architecture and production practices (e.g. row width) are changing over time.  Current guidelines provide recommendations for planting date and seeding rate independently, while seeding…Continue readingLarge Seeded Bean Seeding Date and Seeding Rate Study

Small Seeded Bean Seeding Date and Seeding Rate Study

Current production guidelines have separate recommendations for planting dates and seeding rates, while current seeding rate recommendations varies with row width. Growers typically plant beans earlier in lower crop heat units (CHU) regions, to reduce the risk of damage from fall frost. Many people believe that our growing season is increasing over time, which will…Continue readingSmall Seeded Bean Seeding Date and Seeding Rate Study

Small Seeded Bean Seeding Rate Study on 15″ Rows

Plant population studies from the 1980’s developed recommendations for narrow row production. Since that time, there have been dramatic changes in production practices including row width, market class selection, and the plant architecture of cultivars. Collectively, these changes should have a dramatic effect on grower decisions for plant populations for dry beans. Recent planting technology…Continue readingSmall Seeded Bean Seeding Rate Study on 15″ Rows

Anthracnose Control from Tankmixing a Fertilizer with a Fungicide

Growers often apply fungicides to manage foliar diseases such as anthracnose, and tankmix a foliar fertilizer when they apply a fungicide to reduce application costs. It is unknown if the tankmix reduces anthracnose control from the fungicide. The purpose of this study was to measure fungicide performance under moderate to severe anthracnose pressure, with and…Continue readingAnthracnose Control from Tankmixing a Fertilizer with a Fungicide

Time of Day for Fungicide Application Does Not Impact Disease Control

Sprayer technology is available to apply pesticides at any time – day or night. Some growers rely on this technology to manage a larger crop area. Previous studies have found herbicides such as glyphosate are more effective when applied at certain times of the day. This study looks for a similar response from four day/night…Continue readingTime of Day for Fungicide Application Does Not Impact Disease Control

Sulphur Fertilizer in Dry Bean 2019-2023

A reduction in air pollution has dramatically reduced sulphur deposited into Ontario soils over the last 40 years. Sulphur is highly related to nitrogen in crop plants – sulphur is a key component of leaf chlorophyll and nitrogen fixation nodules. In addition, sulphur is a part of methionine and cysteine, two essential amino acids used…Continue readingSulphur Fertilizer in Dry Bean 2019-2023

Dry Bean Seeding Rate Project Results

With the support of six Ontario dry bean producers located in Huron, Perth and Oxford Counties, a large seeding rate trial was conducted over 3 years on approximately 900 acres of cranberry beans, 600 acres of white beans and 200 acres of black beans. The objectives of the project were to: Demonstrate the use of…Continue readingDry Bean Seeding Rate Project Results

Dry Bean Seeding Rate Project Results (VIDEO PRESENTATION)

A dry bean seeding rate project was conducted from 2018-2020 in Ontario farm fields. White, black and cranberry beans were seeded in large plots in a wide range of seeding rates to evaluate aspects of variable rate seeding and to validate recommended seeding rates.  Below is a 30 minute video summarizing the results. Further reports…Continue readingDry Bean Seeding Rate Project Results (VIDEO PRESENTATION)

Marsh Spot

This article was written by Mylene Corzo Lopez, University of Guelph Summary Marsh spot is due to imbalanced nutrient supply to crops, mainly associated with manganese (Mn) deficiencies in the pea and bean plants and is not caused by pathogens such as virus or bacteria. It is most often found in cranberry bean seed. Marsh…Continue readingMarsh Spot
