Any unauthorised sale of seed of these varieties is an infringement under the Act... Flipper has the highest level of resistance to Ascochyta of current chickpea varieties and is the variety of choice when the risk of Ascochyta is high... Kabulis are extremely susceptible to a range of seed rotting fungi and should always be treated with a fungicidal seed dressing before planting...
GRDC Taxonomy:
" Print the page Marketing and use of mould-affected grain often presents a dilemma for growers and livestock producers, and usually comes down to how much the grain should be discounted... The first group is ergot alkaloids, produced by sorghum ergot growing prior to harvest, and the second is aflatoxins, which are mainly produced if sorghum is stored with high moisture content... The results in: shrunken and pinched grain, following drought or from soil fertility constraints discoloured grain, often covered with black, gray, pink or orange fungal growth (mould), after extensive warm, hu...
GRDC Taxonomy:
" Print the page Wheat growers should aim for a plant population of about 1 million plants per hectare or 100 plants per square metre... In Queensland, over the last 20 years, plant populations of 1 million plants per hectare gave the best wheat crops under most conditions... Higher populations did not adversely affect yield, whereas populations fewer than half a million plants per hectare yielded significantly less (see Figure 1)...

The photo gallery will help growers assess the maturity of peanut crops for Streeton, VB97 and NC7 varieties... Please click on an image or its title to view a larger version... One week early - shells without kernels VB97 88%, one week early, shells without kernels...
GRDC Taxonomy:
Many of the following examples were created using the WhopperCropper (on the Agricultural Production Systems Research Unit website) computer program... As a general principle, long-term simulation results suggest that the median yield is greater from LATER sowings of sorghum when the SOI phase is 'consistently negative' (Figure 1)... Soil water can be estimated with a push probe, soil core, or the HOWWET program ...
GRDC Taxonomy:
lucerne flea or clover springtail damage to lucerne, showing transparent windows lucerne flea or clover springtail damage to lucerne, showing transparent windows.. Feeding damage on pasture legumes can be confused with redlegged earth mite damage... The last generation of females lays oversummering (diapause) eggs on the soil surface that do not hatch until favourable conditions return the following autumn...
GRDC Taxonomy:
Jumping spider attacking a fly... There are seven groups of spiders that commonly occur in field crops... Flower or crab spiders - family Thomisidae, Wolf spiders - Genus Lycoa , Nightstalking spiders - Cheiracanthium spp., Orbweavers - genera Araneus and Agriope, Tangle web spiders - Achaeranea veruculata, Jumping spiders - family Salticidae..
GRDC Taxonomy:
Subsoil acidity is becoming a real problem on many scrub soils and may be constraining plant growth... Toxicities of aluminium and/or manganese can reduce plant growth in acid soils... The rates of acidification in any soil type can be minimised by replacing the basic nutrients removed in crop produce (e.g. calcium, magnesium and potassium) as part of a fertiliser program, and by minimising the losses of soil nitrate by leaching via appropriate rotations of legume and cereal grain crops...
Adult Shoot fly (photo by R Corcoran) Severe damage in millet showing deformed heads (photo by S Mitchell).. The damage only becomes obvious when the seed head fails to emerge, or emerges and is deformed or white... All millets are susceptible to Shoot fly injury, although damage appears more prevalent in cultivars Shirohie and Japanese sown after December...
