Sulfoxaflor (Transform WG) has been granted an emergency exemption for use on sorghum to control the sugarcane aphid for 2017. You can read the full details here. There are no changes to the rates or other use directions from last year, so the restriction on bloom is still in effect and the PHI is still 14 days. At the end of the document, it is mentioned that next year the product is eligible for a streamlined review for 2018. The exemption goes into effect on April 9.
AgFax published this article on the feral hog situation in South America. The increasing hog populations (up 500% since 2007) have caused an alarming population boom and spread of the native ‘vampire’ bat species, which have now been documented to use the hogs as hosts. Vampire bats feed on the blood of vertebrate animals and may spread rabies and other viral diseases from feral hogs to people and livestock. This is becoming a grave concern for ranchers in Brazil. Thankfully, there are no documented populations of vampire bat species in the United States.
Topdressing continues in wheat this week, and many producers are fertilizing fields in preparation of corn planting. The weather continues to fluctuate heavily with brief cold fronts that give way to 80° temperatures within a couple days.
Wheat is growing fairly quickly and most fields still have good moisture. As was predicted, it’s been a relatively warm winter and the wheat may be growing a little too well. Last year there was a freeze in late March, and producers are rightly concerned that this warm weather may make wheat vulnerable to the same situation this year.
