Pests! Prevent them from ruining your stored crop

Wednesday, July 26, 2017

With harvest now in full flow, your attentions will be turned to storing your crops. Whether you are storing for short periods of time or long periods of time pests are a problem. Stored grain insect infestations rarely begin in the field. Most develop from small numbers of pests already present in or around farm storage bins. An effective sanitation program can eliminate or greatly reduce the chance of having serious problems with these insects.

Grain WeevilGrain Weevil
These pests develop inside of the grain kernels. They can be very difficult to find & cause heating within the stores. These insect numbers can increase rapidly and damage grain stored at temperatures above 15°C.

 

 

Saw-Toothed Grain BeetleSaw-Toothed Grain Beetle
These beetles develop on the surface of damaged grain. If the grain is stored above 15°C their numbers can increase rapidly. They are very active, and can be easily trapped.

 

 

Rust-Red Grain BeetleRust-Red Grain Beetle
These beetles penetrate through minute cracks within the kernels. They thrive within grain stored at temperatures above 15°C. In hot UK summers they can develop the ability to fly.

 

 

 

So what can you do to help prevent these & other insects from infesting your stored crop?
Pre-Storage – Check your store has been cleaned thoroughly before any grain is deposited into it. Remove all debris from the store and handling equipment, ensuring it is disposed of at a reasonable distance away from the store.
Traps - Some traps are designed for use in the store others for use within the bulk of the grain. Traps have been shown to be 10 times more effective than sampling for detecting low populations.
Sampling – Sampling the grain can help detect insects and mites, but it is less reliable than using traps.
Grain Quality – try to ensure grains (excl. malting barley) are below 14.5% moisture content and at a maximum of 5°C. Oilseed should be stored at 7.5-8% moisture content and below 5°C where possible. Malting barley should not be stored below 10°C. (View our range of grain driers >>>)

So how can we help prevent these & other insects from infesting your stored crop?

DryingEnsuring your grain is clean and dry will help reduce the chance of pest infestation. Try to ensure grains (excl. malting barley) are below 14.5% moisture content and at a maximum of 5°C. Oilseed should be stored at 7.5-8% moisture content and below 5°C where possible. Malting barley should not be stored below 10°C. Our continuous mixed flow driers can be situated indoors or outdoors and are available in capacities from 10tph to 150tph. With a full range of options we can design a drier to suit your needs.

Pre-Cleaning – If you do find yourself with a pest problem, after you have treated for pests you can run the crop back through your plant and our aspirator will help by taking the pests out. Our aspirator pre-cleaners not only remove dust and light fines, they also help remove insects/pests that are lighter than the grain. Our range of pre-cleaners are fully galvanised and are available in capacities up to 150tph. You can find out more about our range of aspirator pre-cleaners by clicking here >>>
