There was some discussion about use of Manipulator on winter wheat. Producers should confirm with the grain receiver whether Manipulator-treated grain will be accepted, particularly where contracts are in place. Conduct a jar test to see how it will tank mix with other products.
Soybean: While some growers on light ground have planted soybeans, most are focused on getting corn seeded or are waiting for soils to dry. Most of the acres that have been planted are around Brant and Oxford. It is expected that Xtend soybeans will offer some advantages for controlling fleabane with dicamba, but post-emergence control of fleabane in soybeans is very difficult. A burndown treatment and a product with residual control is the best approach. More information can be found in recent Ridgetown Breakfast Meeting Minutes from May 30, 2017 and April 10, 2018.
Corn: Progress on corn planting is variable, depending on soil types and rainfall. There has been a fair bit of planting activity around Brant and Oxford, but through eastern Brant and into Haldimand rain has delayed most planters. Clay ground is not yet fit to plant; the top inch may be dry but it is cold and wet below. There were comments that the soil is soft and Haldimand has not yet seen a pounding rain leading to crusting.
Alfalfa: First cut is approaching quickly and the crop has grown more rapidly with the recent heat. Some producers have been testing Priaxor fungicide and visual differences are apparent beside untreated strips in field trials. Priaxor is registered for control of white mould and common leaf spot in alfalfa. Comments at the meeting around the use of Priaxor were that it may help retain bottom leaves, and older stands or fields with more residue may benefit from an application because they are more susceptible to disease.
Lance is also labelled for white mould and common leaf spot, while Fontelis is labelled just for white mould, and Dithane DG and Rainshield NT are labelled for common leaf spot. Priaxor and Fontelis have 14 day pre-harvest intervals, while Lance, Dithane DG and Rainshield NT are only registered for use in seed production.
The next breakfast meeting in Simcoe is on Wednesday May 23 at 7:30 am.
