Directions for use
It is an offence for users of this product to cause residues exceeding the relevant MRL in the Food Notice: Maximum Residue Levels for Agricultural Compounds.

Active Bio-Gibb can be used on a 3-4 week cycle. Application is best made in autumn and spring where the optimum soil temperature range of 6-13 degrees Celsius is likely to occur. In winter, Active Bio-Gibb can be applied in most districts apart from Canterbury, Otago, Southland, and in high exposure areas in other parts of the country, where temperatures are likely to be too cold for a growth response.

Applications should be carried out 1-5 days after grazing, ensuring there is enough green leaf present to ensure foliar uptake . Active Bio-Gibb is best suited to rotationally grazed pasture. If set stocking, remove stock prior to application, and keep stock out for 3-4 weeks before grazing. Stock may be grazed sooner in the 3-4 week cycle if the pasture is likely to become rank. If grazing earlier than 5-7 days post treatment, the likely result is little or no benefit. Soil moisture and fertilizer levels need to be adequate to support pasture growth. Do not apply to rank pasture, ungrazed pasture, pasture less than 1 year old, or on paddocks containing livestock. As weeds also respond to Active Bio-Gibb, avoid spraying paddocks with toxic weeds or high weed populations that may taint milk.
