Conserve Plus – Robust and Flexible Grain Protection!

Conserve Plus

Conserve Plus Grain Protectant was launched by Dow AgroSciences twelve months ago to replace Conserve On-Farm Grain Protectant. Conserve On-Farm was registered for use on all cereal grains, except malt barley, maize and rice. Conserve Plus solved this issue by removing chlorpyrifos methyl from the formulation, as residues of this active ingredient are not accepted in domestic and some export markets.

Conserve Plus contains the active ingredients s-methoprene and spinosad, and must be mixed with an organophosphate (OP) partner to control rice weevil. For most cereal growers this will be Reldan™ Grain Protector (active ingredient, chlorpyrifos methyl) but for those growing malt barley and maize, Conserve Plus must only be mixed with fenitrothion.

With’ identity preserved’ systems, in addition to normal global grain marketing idiosyncrasies, being able to store malt barley, in particular, on-farm for extended periods, with the security provided by Conserve Plus, has proven to be a game changer for many growers.

“It allows growers to use another active to mitigate resistance in stored grain pests. It allows older storages to be utilised to put malt barley in and not having to rely on using gas sealed type silos where we’re using phosphine. So it’s going to help prolong the life of phosphine as well. It also gives growers a more flexible opportunity to store, particularly their malt barley, and work with their marketer in terms of the markets they’re wanting to put their particular barley into” explained Australian Grain Producers Association Chair Mr Andrew Weidermann.

Conserve Plus still has a 24 hour withholding period, which allows growers the greatest flexibility in being able to either respond to a market need or to feed to stock soon after application. The higher dose of both spinosad and s-methoprene with Conserve Plus confidently provides nine months control of all key grain storage pests when mixed with an OP.

“The new 5L Conserve Plus pack offers larger storers a better value offer. We’re also retaining our 500 mL bottle, to suit those treating smaller holdings of seed or feed” outlined Mr Jon Dadd, Dow AgroSciences Grain Protection Business Manager.

CRT Agronomist, Ed Blackburn from Cudgegong Rural, detailed how the age and condition of many on-farm storage facilities, coupled with the closure of many local receival sites, had made the grain storage pest issue more widespread: “Many of the on-farm storages around the Dunedoo/Coolah district are unsealed and also don't have aeration, meaning a complete fumigation, and lowering the temperature is often not possible. Now that dichlorvos has been banned, guys with infested grain and old silos have nowhere to go when they come across an infestation.”

“Being able to put Conserve Plus on grain for not much more cost than a product like Reldan™ pluS IGR is a godsend for many’’ he added. “The results to date with Conserve have been as good as anyone could hope for, with no reported infestations of any grain that has been treated.’’

Conserve Plus is sold as an agency product under the control of product supply programme, which requires that agents complete the Conserve Plus on-line learning module as well as face-to-face training. When selling treated grain, a commodity vendor declaration must be provided to the buyer so there is no subsequent use of Conserve Plus, leading to a potential MRL exceedance, and to identify what OP has been used, which dictates which market the grain can be sold into.

“The industry has shown it is able to responsibly handle this situation, with no residue incidences reported to date” stated Jon. “This season there is an updated decision tree and wallchart planner, to assist growers to identify what OP to purchase. This material reflects changes in export markets; there are no associated changes affecting grain to be consumed within the domestic market.”
