Grandevo® Bioinsecticide Removes Bee Warning from Label

by

Gives growers a tool to protect crops while not harming key pollinators 

Marrone Bio Innovations, Inc. (MBI), has received U.S. EPA approval to delete the bee toxicity warning statement from its Grandevo® Bioinsecticide label following a review. The removal of the toxicity statement is supported by third-party field evaluations that show Grandevo has no increased mortality or detrimental effects to honeybees. The key study was conducted in central North Carolina during the summer of 2012. The month-long hive study compared the mortality rates of Grandevo versus a known toxic pesticide reference treatment and a water treatment control.

by

Findings originally published in Bee Culture magazine, April 2013

Eurofins Agroscience Services, Inc. conducted a study in summer 2012 to determine the effects of exposure of Grandevo® bioinsecticde on honey bees. The results showed: (a) no statistically significant increase in mortality of honeybees during the post application period, (b) a temporary decline in flight intensity was observed during the exposure period, indicating a temporary, but non-lethal repellency effect, (c) the Dimethoate treated tents had rapid and high mortality.

Biopesticides acquire mainstream status

AGROW_NEWSA flurry of corporate activity in biopesticides by big crop protection companies has cast the spotlight on this sector. Sanjiv Rana examines the implications for the biopesticide sector

The intervening year since the publication of Agrow’s first annual
biopesticide supplement in April 2012 has been an eventful
one, to put it mildly. One could even venture to say that the past
several months have transformed the biopesticide sector, firmly
establishing it as an intrinsic part of the crop protection industry.
Things have moved quite some way from Agrow’s proclamation
last April that the sector was no longer considered fringe; when
quite a few people within the biopesticide industry were still
wary of the tag “snake oils”, and when the big crop protection
companies were quite circumspect about their intentions
regarding biopesticides and seemed to be merely testing the
waters.

The Future of Weed Control

MarroneBio_IMG_2022_webWhile high costs are still a hurdle to overcome, bioherbicides are in the works and could be a weapon in the struggle against herbicide resistance.

Researchers in Canada and the United States are developing bioherbicides that will not only give organic and conventional farmers more weed control options, but also, in some cases, control herbicide-resistant weeds.

Bioherbicides are synthetically produced compounds identical to chemicals found in nature. They may be sourced from micro-organisms or plants. Bioherbicides can also include whole microorganisms that infect weeds.

Currently there are no bioherbicides registered for use on agricultural crops in Canada, but researchers with Agriculture and Agri-Food Canada (AAFC) are working to change that.
