New Neonicotinoid Pollinator Protection Labels Updated

👤Angus Catchot, Extension Entomologist 🕔17:03, 1.May 2014

We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met.

Management Practices to Reduce the Development of Fungicide Resistance in Soybean: Part III, Strobilurin-Resistant Frogeye Leaf Spot in Mississippi

Management Practices to Reduce the Development of Fungicide Resistance in Soybean: Part III, Strobilurin-Resistant Frogeye Leaf Spot in Mississippi Updated

👤Tom Allen, Extension Plant Pathologist 🕔15:16, 11.Apr 2014

Strobilurin-resistant frogeye leaf spot continues to be a topic of conversation. During 2012 two MS counties were confirmed to have strobilurin resistant frogeye leaf spot. Since that time a large survey has been conducted in MS to determine how widespread the resistance is within the fungal population in MS.

Management Practices to Reduce the Development of Fungicide Resistance in Soybean: Part II, Choosing Fungicide Products and Rates Updated

👤Tom Allen, Extension Plant Pathologist 🕔23:05, 1.Apr 2014

Fungicides have become an important management alternative for diseases such as frogeye leaf spot. However, with the addition of the strobilurin-resistant fungus responsible for frogeye leaf spot, caution must be taken when applying fungicides to not increase the likelihood of fungicide resistance from developing. The specific characteristics of the main fungicide classes labeled for application in soybean systems are outlined. In addition, a table that includes the specific components of the pre-mix products when the labeled rates are applied is included.

Soybean Disease Update: September 21, 2013 Updated

👤Tom Allen, Extension Plant Pathologist 🕔15:25, 21.Sep 2013

Soybean disease questions still consider to be raised throughout MS. Even though soybean rust has been detected in 45 counties to date it appears we will have another season where yield losses as a result of soybean rust will be extremely limited and may only have occurred in a handful of fields. When making plans for next year consider sampling for nematodes in light textured soil classes. In addition, planting a frogeye susceptible variety in several years in a continuous soybean system may increase the likelihood of frogeye causing substantial yield loss.
