Plant health top tips - November: Communicate your biosecurity requirements

If it can move, it can carry pests, weeds and diseases. For this reason, it is important to communicate your biosecurity requirements to all people entering farms. Never assume people know the biosecurity measures you have in place for your farm.

There are a number of ways you can communicate your biosecurity requirements, including:

Water stress and yield potential: the research

Recent research has looked at the impacts of early season water deficits on fruit production, fruit retention, boll distribution, seed and lint yield in high retention Bollgard ll variety Sicot 71BR cotton.

Experiments were conducted over two seasons (2006-07 and 2007-08) at the Gatton Campus of the University of Queensland. The research consisted of four experiments which had different planting dates, area, rainfall and irrigations after the stress period.

All four experiments consisted of three different water treatment scenarios which included:

Plant health top tips - August: Time to start pre-season planning: Consider your IPM strategies for managing pests and beneficials

With the 2020-21 season approaching, now's the time to be undertaking preseason planning to reflect and consider strategies on how to manage pests and beneficials.

Integrated pest management (IPM) uses knowledge of pest biology, behaviour and ecology to implement a range of integrated tactics to supress and reduce pest outbreaks and reliance on insecticides for their management. IPM supports the long-term management of pests, maintains profitability, reduces the risk of insecticide resistance and minimises risks to human health and the environment.

Plant health top tips - July: Set your field up for the best start with disease resistant varieties

Endemic diseases such as Verticillium and Black root rot can inhibit production and be costly for growers and consultants. Integrated disease management (IDM) strategies are important for controlling and reducing the impact diseases can have on farm. In back-to-back cotton fields, the disease risks are higher, increasing the importance of using a range of IDM strategies such as planting resistant varieties.

Plant health top tips - June: Develop a farm biosecurity plan.

Your farm. Your biosecurity risks. Your farm biosecurity plan.

The best defence against unwanted pests, weeds and diseases is to implement on-farm biosecurity practices. Simple measures and practices built into everyday routines can help protect your farm from the introduction and spread of these pests. Developing a farm biosecurity plan helps growers assess the likelihood of how pests, weeds and diseases could potentially be introduced or spread on farm and decide on the appropriate measures to minimise these risks.

Scouting for silverleaf whitefly (it's like an episode of CSI)

This season, three of the CottonInfo REOs decided to do a deep dive in the life cycle of the silverleaf whitefly (SLW). Andrew McKay (Border Rivers) , Janelle Montgomery (Gwydir, Mungindi)  and Amanda Thomas (Macquarie Valley) donned the white lab coats and pulled in some expert advice from Dr Jamie Hopkinson of QDAF fame. A wise man (Dr Robert Mensah) once said to find the insect, you must think like the insect. With that in mind, the three intrepid explorers headed out into the fields in search of SLW populations...
