Hatching larvae in late March or April, depending on how many warm winter days we've had, will enter the spaces between bud scales
and make lace out of the tender foliage inside.
Don't forget that if your peaches, nectarines or almonds suffered damaging red and purple leaf blistering caused by the peach leaf curl fungus last year, the infection will still be lurking on the bark and bud scales
, ready to attack this year's new leaves.
The color of pubescence on bud scales
of each plant was recorded as either brown or white.
Budbreak was regarded when a green tinge was seen beneath the bud scales
; this evaluation was performed weekly.
Persistent feeding by large numbers of mites results in reddening and swelling of the base of the bud scales
. Buds appear rosetted, are delayed in their development, and often fail to open.
Trees are so easy to study that most existing field guides emphasize close-up features like bud scales
or leaf hairs.
Dormant lateral buds on most woody plants are protected by a number of overlapping bud scales
. As the bud begins new growth, these scales fall off, leaving bud scale
scars on the stem.
The leaf scar protrudes under the bud, which is shield shaped, and the outer bud scales
. Bud scales
are tiny scales that cover a bud before it opens and begins to grow.
The adults emerge in the autumn and lay eggs under the bud scales
. The eggs hatch in the spring and the larvae infect the growing twig.
The colonies then survive the winter in bud scales
and cracks in the bark ready to infect the young leaves as they appear in spring.
You can then repeat this next February but there is a major warning - do not spray if we have a mild winter and the buds begin to enlarge as the Armillatox can get into the bud scales
. It acts as a total sterilant and is very effective.
Shrubs 2-4 m tall with branches in whorls; branchlets in 3's or subopposite or alternate, dark-brown to yellow-green; buds ovoid, 2 mm long, yellow-brown, the bud scales
persistent, ovate to triangular-lanceolate, keeled, 1-1.5 x 1 mm, yellow-brown to gray-brown.
Peach leaf curl is caused by a fungus (Taphrina deformans); rainwater-spread spores enter and infect leaf buds as the bud scales
separate and expose the leaf tips.
On every living branch and twig of every shrub and tree, tucked within myriad buds blanketed by bud scales
from frigid weather, are countless tiny, fully formed baby leaves.
