Much of the province received welcome showers over the weekend. A few areas were hit with heavy rains that caused flooding in low lying areas. In most cases water drained away quickly but standing water could still be found in some fields two days after the rain. See picture #1. Flooded soybeans on June 1st, […]
Over the last 10 years there has been increased interest in applying foliar fungicides to soybeans in Ontario. Liquid in-furrow fungicide application is also now being used in more US states on soybeans. Many trials have been conducted in Ontario to assess the yield and seed quality benefits of foliar fungicides. Very little work has […]
Various areas in the province received frost in September and there continues to be concern the impact subsequent frost will have on the soybean crop. The extent of injury will depend on the stage of development as well as the length of exposure to frost. MECHANISM Low temperatures injure plants primarily by inducing ice formation […]
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 […]
How late can you apply post emergent soybean herbicides without causing significant injury and yield reductions? Most herbicide labels specify a maximum crop stage (Table 1). A three year study by Dr. Peter Sikkema reveals that of all the herbicides tested, Pursuit (imazethapyr) and Pinnacle SG (thifensulfuron) should not be applied at advanced crop stages […]
Markets continue to move towards quality assurance through IP production whether for IP soybeans or other crops. There is no standard contract for IP or non-GMO production. Each contract reflects the requirements of the end user. Premiums vary with level of management, cost or production risk. Just as “no one shoe fits all”, producing for […]
The Ontario Soybean Growers began a soybean yield competition in 2008. The results were impressive! The winner yielded 72.1 bu/ac near Seaforth. These yields are good examples that with the right weather, soil type, and management, large yields are possible in Ontario. With the big yields and excellent prices in 2008, some producers grossed over […]
