talked about a few things today
first we talked about what research does in terms of impacting plant production.
research its used to find new plant varieties (eg downy mildew resistant lettuce), machines (eg olive harvester), insecticides (eg fungal sprays), management tactics (like IPM) and planting densities and fertilizer rates.
we talked about qualitative and quantitative measurements for plants
a few qualitative factors for lettuce:
FREE OF INSECT PESTS, SNAILS AND SLUGS
- this can be achieved using pellets and insecticides
- one can clear typical hiding places of snailes etc, or use IPM which could include predatory insects such as wasps
- companion crops / aphid repellants such as parsley can be planted to keep aphids away (they dont like the smell)
UNIFORM SIZE AND HEALTHY APPEARANCE (COLOUR)
this can only be done with adequate nutrients (biggest determiner of healthy colour) and lots of water.
the last thing we did was look at pesticide labels, they all basicaly say the same thing in terms of safety. use only as directed, keep out of reach of children, call poisons info centre if you ingest it, if possible try force vomitting.
