Aphids no match for winter cereal treatment

Published on 08/06/2016

Kaiso 50WG from Nufarm is a synthetic pyrethroid insecticide that contains 50 g per kg of the active ingredient lambda-cyhalothrin, but its key point of difference is its formulation.
Developed and patented by Nufarm, the Sorbie Technology found in Kaiso 50WG combines the benefits of emulsifiable concentrate (EC) and water dispersable granule (WG) formulations.
It looks like a water dispersable granule, but once added to water, behaves like an emulsifiable concentrate, meaning easy measuring and mixing, with no dust to worry about and no rinsing of measuring jugs or containers required.
This is different to other products available in the market with the same active, which are either EC or SC formulations.
Farmers and contractors appreciate Kaiso 50WG’s unique combination of ease of use and efficacy, Nufarm says.
“It has all the user friendly handling and mixing attributes of a WG, including stability, volumetric measuring and enhanced operator safety e.g. no splash, non flammable and easy clean up if spilt, but it functions with the same efficacy parameters as an EC formulation when it is mixed with water.”
In its first year of sales the biggest demand for Kaiso 50WG was from cereal growers looking for effective aphid control.
Aphids are the primary vector for BYDV, which can be devastating for yields in a bad season, with losses of up to 40 per cent recorded.
Seed treatment protects young wheat and barley seedlings in early stages of establishment but once this wears off the plants are at risk of attack.
Typically, infections occur when infected adult aphids fly into newly emerging crops in the autumn.
If not controlled, these then reproduce to create populations of aphids which are responsible for secondary spread of BYDV
within the crop and further movement into other fields.
The warmer the temperature, the quicker the aphids reproduce, build up and spread. Last season was characterised by rapid rise of aphid numbers in winter cereals, with resultant disease impact.
Cereals are most susceptible to BYDV infection during the first 10 weeks after emergence. Because very low numbers of aphids
can cause widespread BYDV infection, it is essential to control aphid numbers before they become a problem, Nufarm advises.
As well as cereal crops, however, Kaiso 50WG is also creating interest among growers as a valuable option for control of many insect pests in maize, onions, vegetable and forage brassicas and other fruit and vegetable crops.
Nufarm is also continuing to develop it for use in other crops – recent registrations include kumara and squash.
Kaiso 50WG qualifies for Agrecovery.
