short, spray in the evening of a
humid day. To check the humidity,
spray water on the plants and see
how fast it dries. If it is humid,
evaporation will be very slow even
in the day. In this case, you can
spray in the daytime. In green-
houses, you can spray in a rainy
day, or you can increase humidity
and spray. Smartphone apps nowa-
days provide you with information
on humidity and dew point of
each region.
Pesticides need to coat the target in order to be effective. To increase wetting power, you
must use soft water. The more JWA you add, the more wetting power it has. Picture on left is
0.5 L (1.1 lb) of JWA mixed with 500 L (132 gal) of water. Center is 1.5 L (3.3 lb); right is 3 L
(6.6 lb) of JWA. The leaf is taro leaf which even the commercial chemical pesticides cannot
wet easily. Use soft water with JWA for best results.
If you spray pesticide on a clear, dry condition, pesti-
cide that reached the target will soon evaporate and
be gone. If you spray in humid and cloudy condition,
the pesticide will remain on the target for a long time,
and even if the pest moves, there will still be pesti-
cide everywhere.

Natural Pesticides

Selection of nozzle is also important. Nozzles that can make ine particles
are best. Finer particles mean that you can use less pesticide but still have high
pest control. For best results, spray thoroughly so as
to fully and completely wet the plant. In case of
fruit trees, if the trees have lots of water sprouts and
leaves, the pesticide will not reach all corners and
have less effect. Pruning and branch shaping meth-
ods can help increase pesticide effect. Make so that
the tree can receive full sun and air; it is good both
for the trees and pesticide use.
