Red Savina – 5g/L fresh weight (about 3 ripe fruits).
Must use personal protection equipment (PPE) when preparing the chillies and spraying:
Collect mature to ripe fruits of selected chili variety.
Crush and pound the chilies, working them into a paste.
Place the paste on a fine muslin cloth and bring the sides together making a cloth bag enclosing the paste. Place the cloth bag in a bucket adding sufficient water to cover the bag for at least 1 hour, preferably overnight.
After soaking, squeeze the juice from the bag with hands protected by rubber gloves or plastic bags.
For each 1L water of the final mix, add 10ml (1 bottle cap) cooking oil and 5g (1/2 bottle cap) bar soap (preferably vegetable Castile soap).
Check to see if the mix contains plant material which might block the sprayer. If it does, strain through fine muslin or a metal strainer.
Add water to achieve final volume; pour into the sprayer, and use.
Adapt formulation to 10L or 15L mixture to fit hydraulic knapsack sprayer.
Used to control aphids on a range of vegetable crops, thrips on eggplant, and to disrupt the symbiotic relationship between ants (e.g., white-footed ant), aphid and scale insects, particularly Icerya seychellarum.
