target weed

Categorised under:

Catalogue: Ground Cover
Small, early tillering weeds should be the target of Group A herbicides; these herbicides are less effective when weed size increases.. Many northern growers are now dealing with grass weeds in fallow that are not well controlled by glyphosate, with grower feedback indicating that alternative solutions to control these weeds are required... Research by the GRDC-funded Grower Solutions Groups has demonstrated that the use of Group A herbicides in fallow can be a viable option to control young grass weeds in certain situations...

The benefits improve crop health and crop competitive ability against weeds and the effectiveness of pre-emergent herbicides... When used as a post-emergent product, little of the herbicide gets to the roots and the control of established weeds is often very poor... benefits arise when the weed is prevented from setting seed as there are no increases to the seedbank and, as a consequence, fewer weeds in the future...

A positive test result confirms the need for alternative tactics or herbicides... Assessing weed population density The most accurate way to estimate the population of a weed in a paddock is to count the number of plants in an area of known size at a number of locations... Estimating potential weed population density Potential weed population density can be estimated in a number of ways, such as: When weeds are setting seed, count the number of seed-heads or pods, and the number of seeds per pod or seed-head, from a given sample area...

integrated weed management relies on a range of tactics, both chemical and non-chemical, and multiple attacks to keep weeds successfully in check... recent surveys have shown that ryegrass numbers in paddocks are very low, even where herbicide resistance has been recorded... crop competition Crop competition is driven by crop type and variety choice and works by using crop uniformity, density, vigour and good agronomy to outcompete weeds...
