(Australian Cotton Growers Research Association, 2004-08-12)Cotton (Gossypium spp.) has retained its prominent position in the international arena despite stiff competition from synthetic fibre. One of the major cotton producing countries in the world, occupying the third place ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Sicot F-1 is a new cotton variety released in 2004. It has been developed specifically in response to the appearance of a new unique strain of the Fusarium wilt pathogen in Australia. This article describes the identification ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Cotton fibres, or lint, are very long single cells containing almost pure cellulose. The fibres develop in the weeks after flowering from single cells on the surface of the young seed. Each fibre cell is small at first but ...
-
(Australian Cotton Growers Research Association, 2004-08-12)One step in the production of transgenic cotton is the regeneration of whole plants from undifferentiated cells (calli) in which the gene of interest has been inserted. The first stage is a crucial one and involves producing ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Cold shock at temperatures below 11C was previously believed to delay cotton development. This paper tested whether exposure to 10C for 10 and 20 nights affected tissue viability. Experiments were conducted using plants ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Airborne volatiles emitted by flowers and other vegetative plant parts that attract insects for feeding and egg-laying could be useful in pest management. Over the last 6 years or so, we have developed blends of plant ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Two of the major fungal diseases of cotton in Australia are fusarium and verticillium wilts caused by the fungus Fusarium oxysporum. F.sp vasinfectum (Fov) and Verticillum dahliae respectively. Both pathogens infect seedlings ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Integrated pest management (IPM) is currently the most acceptable approach to pest control in the Australian Cotton Industry. The adoption of IPM in the cotton industry may be regarded as a continuous journey of discovery. ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Nuclear polyhedrosis virus (NPV) and Bacillus thuringiensis (Bt) are the most commonly used biopesticides for the control of Helicoverpa spp. larvae on cotton crops in Australia. These naturally occurring entomopathogens ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Petroleum spray oils (PSOs) have been used for many decades to control a wide range of crop pests (Beattie et al 1995) and are known to have little impact on natural enemies of crop pests (Mensah et al 1995). They form an ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Petroleum spray oils (PSOs) are now an essential part of many integrated pest management (IPM) programs in agricultural crops (Beattie et al. 1995; Mensah et al. 1995). Despite these benefits, the use of PSOs has been ...
-
(Australian Cotton Growers Research Association, 2004-08-12)The over reliance on, and widespread use of, synthetic insecticides has led to resistance, increased concerns about the long term environmental impacts, and public health issues (Smart et al 1994). These issues of cost, ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Trichogramma pretiosum Riley is an important parasitoid of heliothis (Helicoverpa spp.) eggs throughout the Darling Downs. In the past heliothis have been managed using broad spectrum insecticides such as pyrethroids and ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Trichogramma pretiosum is a key natural enemy of heliothis (Helicoverpa spp. ) on the Darling Downs. The data presented here describe some of the biological parameters of T. pretiosum, and may be useful in future population ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Sorghum is extremely attractive to ovipositing heliothis (Hencoveipo armigero) moths. Some cotton growers on the Darling Downs are intercropping cotton with sorgum because they believe that sorghum may act as a beneficial ...
-
(Australian Cotton Growers Research Association, 2004-08-12)There appears to have been a change in the importance of pests presenting cotton over the last decade. This has involved former secondary pests, such as aphids, A. gossypii, minds, Creontiodes spp. , green vegetable bugs, ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Many beneficial arthropods exhibit life-history omnivory (Polis & Strong 1996), in that they include honeydew, floral nectar, extra-floral nectar and/or pollen in their immature or adult diet (Hagen 1986; Coll & ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Determining the impact of species considered potentially important natural enemies of crop pests is crucial for making robust management decisions as part of an IPM programme (Ives 1980; Johnson et al. 2000; Wilson 2002). ...
-
(Australian Cotton Growers Research Association, 2004-08-12)There is increasing interest in utilising Trichogramma egg parasitoids against helothis(Helicoverpa spp. ) in cotton, and crops that may act as sources of parasitoids for cotton -such as sorghum. Very little has been ...
-
(Australian Cotton Growers Research Association, 2004-08-12)Silverleaf whitefly (SLW) is an introduced pest to Australia, having first been discovered in the early 1990's. It was not until the 2001-02 season that a serious outbreak occurred on the Central Highlands and to a ...
