Crop Care has collaborated with Nufarm and the Peanut Company of Australia to carry out fungicide residue trials that support the welcomed registration change for the chlorothalonil based Barrack 720 and Barrack Betterstick.
Chlorothalonil based fungicides play an important role in peanut growers fungicide rotations, which are essential for managing the crop’s resistance issues.
The use of on peanut crops has previously precluded peanut growers from later harvesting peanut hay for cattle feed as a second income stream.
Pat Harden, Peanut Supply Manager (Bundaberg) of Peanut Company of Australia explains that “Peanut growers have had to make the decision at the beginning of the season - whether to use chlorothalonil, or whether to bale hay, as one precludes the other.”
The Australian Pesticides and Veterinary Medicine Authority has approved the registration change of chlorothalonil based fungicides Barrack Betterstick and Barrack 720.
Barrack-treated peanut stubble can now be used for grazing and hay baling as cattle stock feed with a number of provisos:
- a 21 day withholding period must be observed;
- chlorothalonil treated peanut stubble is not allowed as feed for dairy cattle that produce milk for human consumption; and
- any livestock potentially destined for exportation, that have been fed with chlorothalonil treated crop stubble are to receive clean feed for 9 weeks prior to slaughter.
Barrack 720, one of the chlorothalonil based fungicides from Crop Care is suitable for the control of a number of harmful peanut crop fungal diseases such as:
- peanut rust,
- early leaf spot,
- late leaf spot,
- net blotch, and
- peppery leaf spot.
