What new grain protectants are available?

Grain protectants can be applied to grain for protection against insect infestation – they are not allowed to be used in Western Australia.

In recent times, two new products have become available for on-farm use. K-Obiol Combi and Conserve On-farm For more information, click on the names of each product.

K-Obiol Combi

K-Obiol is a synergised grain protectant for use on cereal grains, malting barley and sorghum. It can be used in any type of storage, sealed or unsealed. It is suitable for use by grain growers and grain accumulators. Like all protectants it is a liquid and must be evenly applied as a dilution to the grain as it is fed into the storage. It is not suitable for oil seeds or pulses. It is for use on un-infested grain and is not recommended for eradicating insect pests when they have infested grain.

The active constituent is deltamethrin. Piperonyl butoxide is added as a synergist; meaning it increases the effectiveness of the deltamethrin. As K-Obiol is based on deltamethrin there are none of the insect resistance problems being experienced with other protectants.

Because protectants are residual there can be concern by grain users that the grain does not contain excessive levels. This may come about from incorrect treatment or double treatment as the grain moves along the supply chain. To protect the end user of the grain, and ultimately the Australian grain growers, a Product Stewardship program has been developed to ensure correct use of the product. The Program will also ensure the product is used in the way that minimises the development of insect resistance and increase it usable life.

Conserve

Conserve Plus

Conserve Plus is the latest addition to the Conserve family. Its formulation combines Spinosad and S-methoprene at 100 gm ai per L. Conserve Plus will be able to be used on all cereal grains, including malt barley. The first release will be the in a 500ml bottle that will treat 50 T grain. Conserve Plus will require a mixing partner to control rice weevil, and as such, Dow AgroSciences  released a 1L Reldan Grain Protector in Sept 2016 to partner Conserve Plus. When used on maize, the OP mixing partner is replaced with Fenitrothion 1000.

Conserve On-Farm

Conserve On-Farm is a grain protectant from DOW that has three active ingredients to control most major insect pests of stored grain, including the resistant lesser grain borer (LGB).
Conserve On-Farm provides six to nine months of control and has a nil withholding period (WHP). Maximum residue limits (MRLs) have been established with key trading partners and there are no meat residue bioaccumulation issues. Conserve On-Farm is a combination of two parts that are applied together. Using Part A and Part B together is very important to get control of the complete spectrum of insects.

Part A: 1 x 5 L of chlorpyrifos-methyl and S-methoprene – controls all stored grain insect pests other than the resistant lesser grain borer (Rhyzopertha dominica)

Part B: 2 x 1 L of spinosad – is very effective on the lesser grain borer, including resistant strains, but has little to no activity on other key species.
