Fungicide (especially chlorothalonil) withholding periods (WHP) and Export Slaughter Intervals (ESI) on pulse crops.

Dear pulse agronomist, consultants & producers,

(Information provided via Pulse Australia)

To help answers some questions & decipher the label information, the below outlines the current state of play.

Why the different labels with different WHP comments?

There are fundamentally two different labels in existence.

Generic labels; these are older labels and all data supporting the label is publically available and can be used/mirrored by anyone.
Proprietary labels; these are the newer labels which still have data protection associated with them and as such is not available to other companies

There are only three current labels with this data being;

Barrack Betterstick Fungicide
Crop Care Barrack 720 Fungicide
Nufarm Unite 720 Fungicde

Under ‘State Control of Use Legislation’ it is a requirement of all users to follow the label of the product applied and not of a similar product.

This is often an issue with growers as logic would suggest that if both products are 720 gai/L of chlorothalonil then what’s the difference once it has been applied.
The difference is what the law says i.e. you must follow the directions of the label of the product used.

Generic Labels:

Have registered claims for their use on Beans – Broad (Faba), Peanuts, Peas.

NOTE: there is no claim for their use on lentil or chickpea and as such these products cannot be legally used on either lentil or chickpea.

If these products are used on beans then the following conditions apply;

Withholding period (WHP) to harvest is 7 days.

This means that once a crop has been treated none of that crop residue can be grazed by any form of livestock.

Regardless of if it is a failed crop, crop cut for hay or a harvested crop

Proprietary Labels:

Have registered claims for their use on Beans – Broad (Faba), Chickpea, Lentil, Peanuts, Peas (Processing).

If these products are used then the following conditions apply:

Withholding period (WHP) to harvest is 14 days.
Withholding period (WHP) to grazing is 14 days.

With the provisos that the grazing withholding period applies only to stock slaughtered for domestic markets.

Some export markets apply different standards and to meet these standards in addition to complying with the grazing withholding period of 14 days, the Export Slaughter Interval (ESI) of 63 days needs to be observed before stock are sold or slaughtered.

An ESI of 63 days means that livestock that have been grazed on, or fed treated forage, silage, fodder or stubble, should be placed on clean feed for 63 days (9 weeks) prior to slaughter.
I understand that some crops are being cut for hay/silage. If this hay/silage is feed to livestock, then an ESI of 63 days applies to that livestock.

DO NOT graze or feed treated forage or fodder to livestock which may be used to produce milk for human consumption.

Clearly there are some differences between the two label types, this is primarily due to the proprietary labels still being covered by data protection until Dec 14th 2015. Meaning that none of the other companies can access this data for the purpose of changing their labels.

Remember that it is a legal requirement of a producer to follow the label directions of the actual product applied.

Future harmonisation of product labels??

In the new year, when the appropriate data is no longer covered by data protection, I would image that there will be a move by many of the generics to mirror the label claims for chickpea and lentil.

This will require them to adopt the WHP and ESI as outlined above.
