This study reports on field trials using Magnet formulation with insecticide to determine the effect of applying the attracticide to a centrally located BollgardII (Bt) cotton crop on levels of Helicoverpa spp.

When comparing BollgardII with conventional cotton, the lower water requirement and higher lint yield of Bollgard II was explained by greater insect damage in conventional cotton.

This pilot experiment at Carroll and Narrabri investigated the yield and fibre quality benefits of application of foliar potassium, phosphorus and micronutrients to a high yielding Bollgard II and Roundup Ready variet

Soil moisture extraction under fully irrigated conditions was the same in BollgardII and conventional varieties, except where season length allowed later crop and leaf growth in the conventional variety.

BollgardII accumulated yield faster than conventional cotton due to higher retention combined with a very low proportion of tipped plants.
