The development of resistance allows individual insects to survive an exposure to insecticide that would kill individuals from a 'normal' population. The sheep blowfly, Lucilia cuprina has developed resistance to at least three classes of insecticides that have been used to treat or prevent flystrike on sheep. To read more about the evolution of resistance please click here. There are a number of management strategies that can be adopted to minimise resistance, or at least delay the onset of resistance:
  • Adopt an integrated pest management strategy that incorporates non-chemical controls such as genetic selection and timing of shearing and crutching to reduce the reliance on chemicals. Only use insecticides when absolutely necessary. This reduces selection pressure.
  • If treatment is needed, make sure it is applied effectively - do it right once!
  • Know which insecticides belong to which insecticide class
  • Use insecticide from different classes for treating and preventing flystrike. This is particularly important if relying on insecticides to kill larvae on flystruck sheep
  • Be aware that resistance to one insecticide may cause a cross-resistance

For more information on treatment options please contact your local TP Jones or Tas Ag Services Representative



Finally, some very welcome rain… Although perhaps a bit much in some regions, most crops will be happy of the break from the hot, dry conditions we have been experiencing.
Poppies are progressing well and most are well into early hook and flowering – water is the most important factor for poppies now and if you have managed to escape systemic mildew you may be well on the way to a rewarding season.
Grass seed and cereals continue to progress well and are really enjoying the warmer weather, especially those under irrigation. Some southern crops experienced a late cold snap resulting in frosted heads (see pics…). Remember that if some weeds have escaped the early weed control program, there is still an opportunity of a salvage spray as the heads dry off, closer to harvest.
Another thing to be mindful of in the later stages of development is the army worm caterpillar, which can nip out the grains from the maturing head. If you suspect the presence of army worm, or any other pests, please contact your local TP Jones Agronomist for identification and control options.
Potatoes have emerged well and most have received a burnoff spray for weed control. By this stage, as with most crops under the current conditions, keeping irrigation at an optimal level is the best way of ensuring the best for your crop leading into the summer months. This is especially important on sandier soils, which are very hard to re-wet once they dry out completely.
Peas are in and emerging quickly, along with the weeds! It is important to remember under these hot, dry conditions to apply herbicides at the optimal time to get the best result.
Applying herbicides following irrigation, in the correct water volume and at the optimal time of the day (generally the cool of the evening) will greatly help in achieving the best possible results. Even though forage crops may be developing quickly under the current warm conditions, it is important to remember the correct days-to-maturity-to-grazing (especially with regard to rapes and brassicas).
The correct date is calculated from crop emergence NOT planting date. Being mindful of correct grazing times will greatly reduce the risk of any stock health issues.
Please contact your TP Jones Agronomist or Animal Health Representative if you have any concerns.


Due to the recent rain activity numerous cases of Blackberry infestation have been reported. Blackberry grows vigorously and can infest large areas quickly. Negative impacts include:
  • reduced available grazing land (most livestock find blackberry unpalatable) and restricted livestock access to water (when growing densely around waterbodies)
  • reduced productivity of land caused by shading out of pastures and crops, and competition for soil moisture and nutrients
TP Jones and Tas Ag Services stock several products to help control Blackberry in your paddocks including:

For the control of environmental and noxious woody and herbaceous weeds as specified in the Directions for Use Table.

For Improved Penetration & Faster Uptake of Roundup® , Weedmaster® and other Herbicides
Contact your local representative for more details.
