Farmers that have not completed corn planting may be considering switching from corn to soybean or keeping corn, but switching to an earlier hybrid. Both of these decisions can be complicated and depend on yield and other information that are imprecise estimates and highly dependent on weather conditions the crops experience throughout the rest of the growing season.
Delayed planting seasons create a lot of frustrations for everyone involved with planting crops. One of the agronomic questions that comes up when planting is seriously delayed is whether farmers should consider switching from their normal full-season maturity hybrids to shorter-maturity hybrids.`
Although UAN (urea-ammonium nitrate) and many pre-emergence products can be applied to emerged corn, using UAN as a herbicide carrier enhances the foliar activity of products and may result in foliar damage.
Forecasts of unusually low temperatures in late May or early June can set off warning bells for corn growers and lead to fearmongering about frost damage to young corn. Even if frost does not form during these cool nights, minor leaf surface damage can still occur as a result of radiational heat loss from the leaves during cool, calm, clear nights. Such leaf damage results in a curious leaf symptom that may remind you of freezer burn.
The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is making available for public review and comment a draft environmental assessment (EA) and preliminary plant pest risk assessment (PPRA) following a petition received from the Monsanto Company.
Monsanto's ongoing efforts to try to take over Swiss agrochemicals firm Syngenta, a rival whose product portfolio offers an array of agricultural chemicals, could spark a sell-off or de-emphasis of a product line that last year brought in roughly $5 billion, or a third of total revenues for Monsanto, according to industry sources.

As is the case in most years, there has been no shortage of discussion and analysis this spring of the potential impact of the timeliness of corn planting on yield prospects. Each effort tends to bring a slightly different perspective to the topic.
