The Australian cotton industry has now had three seasons of commercial scale use of Bollgard II, the two Bt gene product developed by Monsanto for insertion into cotton for control of Heliothis. This follows seven years of use of the single gene Ingard product. A combination of factors including: excellent efficacy against the target pest, a rapidly expanding suite of varieties containing the product, a stepwise increase in the technology fee, no cap on the percentage of a farm that can be grown to Bollgard II and management benefits associated with its use has seen a rapid increase in the acceptance of the technology across both the irrigated and dryland sectors of the industry
