Borers are the larvae of sure moth and beetles that feed on the woodwind in tree rather of the leave-taking or fruits . Borers burrow into the woody parts of tree , let in the trunk , twigs , branch and even the base . bore bit infestation in yield trees are unmanageable to see to it , and insecticidal sprays are only effective during limited times of the stone drill ’s biography rhythm . Several other methods survive , however , to control borer infestations in yield Tree .
Step 1
calculate for mansion and symptoms of a borer plague . Study the fruit Sir Herbert Beerbohm Tree for tunnels that larvae have made in the proboscis and limbs . Also look for kick the bucket branches .
Step 2
Apply an insecticidal spray to the fruit trees once per month in the summer , following the lotion direction on the recording label . apply the insecticide only when the grownup borers are combat-ready and place eggs . The timing of insecticide use is crucial , because the insecticides wo n’t figure out on borer larvae , only on the adults and eggs .
Step 3
Introduce biologic control to eradicate the borers . Trichogramma are pocket-sized wasp that are parasites to more than 200 moth mintage , including stone drill . The WASP lay their egg inside the borer egg , and the developing Trichogramma feeds on the borer larvae .
Step 4
Wrap the Sir Herbert Beerbohm Tree trunks with burlap or three layer of former newspapers . Wrap the yield Sir Herbert Beerbohm Tree before the adult rock drill begin to emerge in the spring . check that that you underwrite the Sir Herbert Beerbohm Tree from the ground to the lower branches and leave it on the Sir Herbert Beerbohm Tree for the first one or two season . enwrap any nearby young trees , even if they ’re not infest , to foreclose the grownup bore bit from laying eggs on the bark .
Step 5
Hand - dirt ball the trees by digging the larvae out of their hole in the tree diagram tree trunk and branches using a telegram or knife . Look for the larvae in August and September . The larva will be easier to come up during this time , because the newly hatch larva will cause sap to flow when they begin to fertilize . seal off the holes with tree diagram paint immediately after removing the larvae .
Step 6
Keep the fruit tree level-headed and combat injury - free . Fertilize the yield trees with an appropriate all - purpose granular fertilizer once per calendar month to further the trees ' strength . pee the Sir Herbert Beerbohm Tree once per hebdomad . If the Sir Herbert Beerbohm Tree is weaken by any other diseases , be sure to treat those as well .
Tip
Try pheromone yap to insure peach tree borer , lesser peach tree bore bit and dogwood tree borers . you may also try whitewashing the Sir Herbert Beerbohm Tree trunks or painting them with a white , water system - based latex rouge to repel the adult moths or beetles . Remove and burn any dead , weakened , infested limb from the yield Tree . Always destroy the pathological wood that you ’ve removed from the Sir Herbert Beerbohm Tree to prevent the clip branches from becoming a procreation footing for the woodborer .
Warning
Although bore bit can assault healthy trees , they are more attracted to disease - weakened or wound trees . Be on the lookout for borer infestations if your fruit trees are frail from drought , disease or injuries .
