Thrip numbers are now starting to decline and no mirids have been detected yet.

Note that thrips populations will naturally crash in the field at about 50 DAS. This is very typical and this natural decline provides the opportunity for plants to recover. Plants will recover from less severe damage often with no yield loss or delay. This has been shown in southern NSW trials over several seasons.

Early season insecticide spray applications may seem a cheap option at the time but it will have consequences and lead to a reduction in beneficial insect populations.
