| Get
aphids out of apple trees(Clare) Wahoo!
For the first time in seven years, my apple (have only one tree) is
aphid free and healthier looking than ever. I had not realized how
very much the aphids affected the vigor of the tree until I had this,
my first aphid-free spring.
I attribute the difference to the "green
lacewings" introduced from eggs last spring. They really did a good
job--there were evidently not enough aphids left to reproduce and
hold siege on the tree this year.
So if you have aphid troubles, consider green
lacewings. One advantage in them over ladybugs is that they hatch
out earlier in spring than do ladybugs. There are weeks of aphid
attack before the ladybugs hatch out. Green lacewings go to work
early in spring.
Get rid of
squash bugs! Adult squash bugs are nearly impervious
to any insecticide, organic or not. In the evening,
place boards on the soil near your plants. Early in the morning,
lift the boards and you'll find clusters of the little critters.
Brush them off into a bowl of soapy water. Look around for
any early risers already on your plants and pick them off and pop
them into the soapy water, too. After harvest, do some prevention
work for next season. Plan to put all of your squash and other
cucurbits in areas where cucurbits (squash, cucumber, gourds, melons)
weren't planted this year. Clear all debris from that area
so the squash bug nymphs won't have food to grow on.
Hornworms
eating your tomato plants? For now, pick them off
by hand and drop them into a bowl of soapy water. If they're
still small, an application of Bt will have good effect. If
the infestation is severe, use a pyrethrum spray.
Tiny
holes in the leaves of your tomato plants are a sign
of flea beetles. Tomato plants can sustain a fair amount of flea
beetle damage without any noticeable harm, but if the leaves start
dying, try a soapy water spray.
Japanese
beetles begone! Handpick early in the morning and
drop into soapy water. For long term control, use milky spore
or beneficial nematodes. For severe infestations, use pyrethrum
spray.
Apple maggots
The apple blossoms were beautiful and you've got tons
of fruit, but apple maggots can make the whole lot inedible.
Trap the flies by hanging 2-4 strips of tanglefoot in each tree.
Or make your own fly trap by filling jars with a mixture of 1 part
blackstrap molasses to 9 parts water. Be sure to collect all
dropped fruit asap.
Collar those cutworms
Protect seedlings and transplants from cutworms by dressing
them up in 3-inch paper collars. Beneficial nematodes and
trichogramma wasps will prey on cutworms.
Attract ladybugs
to your garden Those cute little spotted bugs are
actually voracious predators who feed on aphids, chinch bugs, asparagus
beetle larvae, thrips, alfalfa weevils, bean thrips, grape
rootworms, Colorado potato beetle larvae, whitefly, and mites, and
many other soft-bodied insects and eggs. It is estimated that
one adult ladybug can consume almost 400 aphids a week.
Ladybugs are very territorial. If you can attract them initially,
they'll usually stick around for many generations. Lure them
in by planting sweet alyssum in your garden. The sweet alyssum
will also draw lacewings (another aphid muncher) and as a bonus
you'll have lovely purple or white blossoms.
Make your vegetable
garden invisible to bugs. Marigolds and calendula
mask the odor of food crops and attract beneficial insects.
Plant these flowers as a border around your veggie patch and the
nasty bugs won't know it's there.
