The use of chlorpropham (CIPC) as a sprout suppressant on stored potatoes is under review by the Advisory Committee on Pesticides following continued detection of exceedances of the Maximum Residue Level in testing by the Pesticide Residues in Food (PRiF) Committee. The outcome of this review is expected after September, and in the meantime Approval Holders have agreed to introduce new recommendations on the product label for 2013/14, with the support of the stewardship group. These are detailed below:
TIMING OF FIRST APPLICATION
First treatment recommended within 3 weeks after harvest (or at the earliest occasion thereafter) even in the absence of signs of breaking dormancy.
TREATMENTS IN COLD STORES
(holding temperature 5oC or below)
Only one application of CIPC up to the maximum individual dose per season recommended. The application should be made before the temperature is reduced below 7°C. Recirculate store air for at least 6 hours without cooling prior to application.
VENTILATION MANAGEMENT DURING APPLICATION
Positive ventilation is recommended in all store types.
There is also a requirement to complete a Stewardship Store Checklist prior to application and this will become a Critical Failure Point in 2013/14 for Red Tractor Farm Assurance.
The Potato Processors’ Association (PPA) has stated that its members will only take supplies from growers who have used an applicator accredited to the National Association of Agricultural Contractors’ CIPC Applicators Group for the coming season. If you are planning to use CIPC next season, it is important to speak with your contractor now to plan your storage and to ensure you follow best practice at all times. Further information, including a list of contractors, appears at: www.cipccompliant.co.uk or contact Sutton Bridge to arrange a briefing session on 0800 02 82 111.

Bud Nip, take a closer look......
The Dangers of Bud Nip in a Compact Sweet Potato Project

The dangers of bud nip, a chemical herbicide also known as Chlorpropham, become clear in a simple yet illuminating message from a young lady named Elise. In the video below, Elise, a slight girl in a blue shirt, is nervous and sweet as she tries to remember her lines and looks down at her cue cards to explain her “Potato Project.”
With the help of her grandma, Elise buys a sweet potato each from three different sources: one from the grocery store, one “organically” labeled from the same grocery store, and one from Roots, a certified organic food market. Each sweet potato is placed in a glass of water in order to track its cultivation of vine sprouts and growth.
The first sweet potato, the one from the grocery store, does not sprout any vines after three weeks. The second one sprouts a “wimpy, little vine” after over a month. The third sweet potato, the one bought from Roots, flourishes with cascading, healthy green sweet potato vines after just one week.
What seems like an innocent fourth-grade science project is actually an informative and effective account of the effects of a commonly used chemical herbicide called “bud nip.” The produce man at the grocery store informs Elise that the first potato won’t sprout any sweet potato vines because it has been sprayed with bud nip. According to the Pesticide Action Network, the dangers of bud nip include toxicity to amphibians and honeybees, important pollinators of crops we eat every day. Bud nip can be found on potatoes, kale, peaches, broccoli and other common fruits and vegetables.
Elise’s sweet potato project is a subtle, but insistent reminder that bud nip and other chemical herbicides harm us as well as the world around us. In her words, “Which potato would you rather eat?”
