GRAIN GUIDE
Risks when purchasing
input resources
The use of untested input resources and the purchasing of input resources from unknown distribu-
tors expose producers to great risks every year. Take note of the following tips when purchasing
and using input resources:
• Make sure that the input provider is a recognised company with a proven record.
• Ensure as far as possible that all recommendations are provided in writing and store these
copies safely.
• Try to keep a record of all purchases as far as possible.
• Check the quality of the input resource. For seed the germination of the seed lot concerned
can be requested, for example.
• Seed treatment should be done by the seed company itself or with certified seed treatment
equipment.
• When purchasing agrochemicals:
– Make sure that the input resource is registered for the purpose for which it is being used.
– Make sure that the company whose input resource is being used is a member of CropLife.
– Make sure that the distribution company is a member of CropLife and that the agent is qualified.
– Consult the 2015 MIG publication of the ARC-Grain Crops Institute.
As a rule, use small control sites to test new input resources before using them on a large scale.
As far as rhizobia bacteria are concerned, it is important to use only registered (L registration in
terms of Act No. 36 of 1947) input resources. The product concerned must also preferably be
recommended by the seed company whose seed is being planted. Do not use new products on a
large scale.
As far as prices are concerned, make sure that you pay the best market-oriented price. Obtain at
least three quotes where possible and do not just accept the first and best price. Members are free
to contact Grain SA with respect to input price trends.

The action of these input resources is not in question, but producers must note that some of these
input resources have not been properly tested or registered in terms of Act No. 36 of 1947. When
considering using such an input resource, you should therefore note the following:
• Make sure it has been registered in terms of Act No. 36 of 1947.
• Insist on long-term statistical and preferably independent local test results.
• Never use such an input resource on a large scale immediately, but rather use it for small-scale
strip trials that can be assessed statistically to measure the performance of the input resource.
• Determine whether it is cost effective to use the input resource.
Grain SA is of the opinion that this type of input resource must first be tested statistically by a
recognised independent local institution for sustainable production improvement with respect to
economic benefit before it can be registered and marketed.
