Young faba bean plants grown in northern New South Wales (NSW) often have crinkly leaves and blackened necrotic growing tips... Crinkly leaf damage in faba beans, as seen in the northern region of NSW, is caused by thrips, not leafhoppers, which are also present when the damage occurs... We also assessed the plant's capacity to compensate for early damage and the effect on yield...

" Developing and demonstrating the role of alternative chemistries and integrated management for crop establishment pests.. Reliance on chemicals to control agricultural pests leads to problems in pest resurgence, secondary pests and the development of pesticide resistance... The findings from the project will improve the way crop establishment pests (including redlegged earth mites) are controlled and lead to a reduction in the unnecessary application of broad-spectrum insecticides...

WA growers are this year being urged to test redlegged earth mites (RLEM) that survive insecticide treatments... As part of a GRDC-funded national project, CSIRO and Department of Agriculture and Food WA (DAFWA) researchers will this year continue to test properties across the State where RLEM are found to survive insecticide treatments... If RLEM survive registered rates of insecticide treatments, or there is suspicion that mites resistant to chemicals are present on a property, contact DAFWA's broadacre entomologists to have mites sampled and tested...

Dr Miles said although preliminary results suggested that insecticide treatments at sowing could potentially provide some crop protection, it was also probable that the insecticides would deter larvae from the zone in which they are active but as roots grow out of the treated zone they could then be damaged by larvae... "It is also possible that the use of seed or in-furrow treatments will have little longer term effect on the density of the population, essentially locking growers into a program of using these treatments to ensure a crop," she said... "Techniques for evaluating the efficacy of seed dressings, in-furrow treatments and possibly side-dressed insecticides are under development which will allow for evaluation at different times post-application to test the longevity of the treatments and their potential toxicity to scarab larvae."..

The extremely low incidence of seed damage assessed in all SA trials is likely to be attributed to the lack of E. behrii pressure during 2005... The aim of the study was to assess the efficacy of several candidate insecticides for the control of E. behrii in lentils... Results obtained from the Vic trial suggest that deltamethrin and esfenvalerate can effectively control damage caused by E. behrii to lentils when applications are timed appropriately...
