Dry weather has significantly reduced forage regrowth and second-cut yields. Many farmers are examining options to increase their forage inventories, including using corn damaged by dry weather for silage. https://fieldcropnews.com/?p=4243 Seeding oats in late-July or early-August following wheat for an early-October harvest can be a useful low-cost option for extending forage supplies. Oats can make […]
Seeding oats in late-July or early-August following wheat for an early-October harvest can be a useful low-cost option for extending forage supplies. Oats can make good feed when harvested at the correct stage of maturity and made into “oatlage” or baleage. Oats are more frost tolerant in the fall than sorghums, and can continue growth […]
The butterfly enthusiasts had a good spring this year with the early arrival of the red admiral butterfly and large flights of other species. Unfortunately for us, that also meant some pests also arrived in great numbers. Speaking of pests has anyone seen this caterpillar in soybeans? This is the larval stage of the painted […]
Dry weather during corn silking and pollination can significantly reduce grain yield expectations. Inadequate moisture can result in poor ear fill or even corn plants without any ear or grain. In extended dry weather situations, farmers can also face the immediate problem of providing adequate forage inventories to feed their livestock. Damaged corn crops with […]
Diagnosing nutrient deficiencies in field crops can sometimes be challenging. That is why I put together the following nutrient deficiency key. Let me know what you think. Click on the above image to download the nutrient deficiency key. […]
Below are examples of corn and soybean injury demonstrated at the FarmSmart field expo, July 12, Elora Research Station (University of Guelph) Scenario 1: Just this past spring, I had contact with a producer who had accidentally applied Guardian Plus (glyphosate + chlorimuron + flumioxazin) post emergent to his glyphosate tolerant soybeans. This mistake is […]
I have had a lot of questions concerning Soybean cyst nematode and rhizoctonia in soybeans recently. In terms of SCN, remember the primary SCN symptom is often no above ground symptoms at all. Growers are advised over the next few weeks to scout for SCN by carefully digging-up plants, gently remove the soil from the […]
Horst Bohner, Soybean Specialist, OMAFRA, Stratford Albert Tenuta, Field Crop Plant Pathologsit, OMAFRA, Ridgetown Prolonged dry conditions can reduce soybean yield at any stage of development, but plants are more susceptible during germination and the reproductive growth stages. Dry soil conditions during germination will reduce plant stands. Severe moisture stress is evident by leaf wilting […]
The hot, dry weather conditions to date have not been very conducive to foliar leaf diseases across most of the province. In most cases, besides high relative humidity, prolonged wet conditions on the leaves are necessary for infection but only under favourable temperatures (16-30oC). What has started to show recently in the southwest are the […]
Soybean growth has been slow in those areas that missed the rains. Fields are now at the R2 (full flower) growth stage. Those areas that received adequate moisture are progressing well and are entering R3 (beginning pod). Soybeans flower over an extended period of time so areas that have been negatively impacted from the lack […]
Harvest is in high gear as far north as Mitchell, and starting in Bruce County. Yields are average, mostly 75 to 95 bu/ac. Poor fields are 60, with best fields at 110. Quality is excellent, with very low fusarium. Protein in hard reds is inconsistent. Sprouting in white wheat is an issue southwest of London […]
Potato leafhoppers (PLH) are being reported at damaging levels in many areas across the province, including areas where they are not typically a problem. PLH dramatically reduces alfalfa yield and forage quality. Reduced stem and root growth, and vigour results in stunting and slow regrowth. New seedings are very susceptible and can be permanently damaged, […]
Our WBC trapping network has been catching relatively few moths over the past weeks but last week some higher numbers were reported. These numbers are still a bit behind what I would have expected considering the warmer weather but the trend is towards increasing numbers. Just last week the scouts were finding quite a few […]
Below is an overview of herbicide injury scenarios presented at the SouthWest Crop Diagnostic Days . Scenario 1: A field of corn has been replanted due to a poor stand. After planting the producer has decided to remove the existing stand as it is effectively a weed to the new crop. Unfortunately weather delayed the graminicide […]
Minutes taken by Dan Docking. Issues Raised. lack of alfalfa regrowth, fungicide on corn, cutworm, leaf hoppers on edible beans, armyworm spraying, yellowing of new growth in soys, adzukis, hail damage in corn – fungicide application and timing, soybean aphids, double cropping soybeans. Alfalfa Regrowth Based on the tough, dry spring many alfalfa plants lack […]
