Monitoring is a requirement under the NZ Avocado AvoGreen programme. If you are going to export, you must register with an AvoGreen operator before the 1st November each year to be allowed to export your crop the following year.

An IPM (Integrated Pest Management) programme is also being designed for the New Zealand Citrus and Persimmon industries, to be implemented in the near future. If you are concerned about managing your pest problems and reducing sprays, please talk to us.

CropCheck Ltd offers a personal monitoring service with full same day reporting. Our independent monitoring service enables you to make an informed decision on whether or not to spray.  We won’t recommend or sell you sprays, just tell you which pests you may need to spray for. 

We have a philosophy that the more informed you are, the better choices you can make. Therefore, we report, not only the major pests required under the IPM programmes, but all beneficials and others pests we see.

Reporting options:

  • Immediate report by text if  over threshold
  • Monitoring report sheet left at orchard
  • Full report via email, or post to grower, adviser, and/or sprayer
  • One-off monitor for Owner-Operators

Monitoring FAQ’s

lower_decorMOB.png

Q:  Why should I monitor as frequently as you recommend?

A:  Our recommendations, and the recommendations of the Avocado Industry Council, have been worked out over many years, taking into consideration the cost of monitoring to the orchardist versus the loss from insect damage. Those who monitor according to recommendations are regularly achieving packout's of 85-95% with little or no insect damage. Those who choose to try and save money and not monitor are achieving a packout of 40-60% with insect damage of 40-60%. If you add up the average cost of monitoring of $1,000 - $1,500 per year and 3-4 sprays per year (because they are timed properly), the cost is little to achieve a payout that is worth having. Lets look at some figures.

If you have an orchard with 100 trees producing 1 bin of fruit per tree that is paying $1,000 (orchard gate price), that equals $100,000 per year. Now take off the cost of monitoring which equals 1 to 1.5 bins of fruit and the cost of spraying at say 2 bins of fruit. Then take off the cost of insect damage, maybe half a bin of fruit (if sprays went on at the right time), you now have 96 bins of export quality fruit left and $96,000 in the bank.

Now if you try and save on monitoring, you will probably have to spray 1-2 extra sprays to get on top of insect infestations, at a cost of $500 plus per spray. That $500 would have paid for nearly 6 months monitoring. From the 100 bins of fruit, take off 40 bins of insect damaged fruit, less the cost of 2 extra sprays, which equals 3 bins of fruit instead of 2. Plus a saving of .5 bin of fruit from less monitoring costs. Your total payout in the bank will be for 57.5 bins of fruit - $57,500 in the bank.

In short, saving on monitoring is no saving.

Note: this is an example only and does not include other on-orchard costs.

Q:  Why are the thresholds so low and what do they mean?

A:  Pest Threshold Levels are set low to avoid as much insect damage to the fruit as possible. The ideal is to get your fruit to market with little or no insect damage.

A pest monitoring showing pest levels AT OR ABOVE threshold gives the grower justification to spray.

Some insects, particularly Greenhouse Thrip and Six spotted mite, can increase in number very rapidly. Therefore the thresholds have been deliberately set low under the AvoGreen protocol, so sprays can be applied at the earliest opportunity.

Q:  How often should we monitor for Green House Thrip?

A:  Greenhouse Thrip can create large areas of blemish in a very short time. Where Greenhouse Thrip thresholds have been exceeded and no spray has been applied, AvoGreen best practice requires us to monitor again in 7-10 days. Once you are over the 2% threshold, it is recommended that 2 sprays are applied within 21 days, to deal to newly-hatched Thrip eggs. Thrip can be a recurring problem from mid January until the end of April and often into May.

Q:  How frequently should we monitor for Leafroller?

A:  Even where fruit are not touching, small caterpillars can be found under webbing on the stem end of fruit. A great deal of damage can occur between one monitoring round and the next. We strongly urge growers to maintain a fortnightly monitoring routine, even when a spray has been applied, as the pests multiply rapidly in warm conditions.


Please note: CropCheck Ltd act in good faith to assist you to get your fruit to the market in the best condition possible, but have no control over on orchard management, or weather events that may affect the quality of fruit at harvest
