Infectivity

Highly

Wilting bacteria can easily spread from one Bradford pear to another via airborne vectors, contaminated tools or even through the soil.

Lethality

Highly

If left untreated, wilting can lead to complete decay and premature death of the Bradford pear.

FAQs on Bradford Pear

Does high temperature accelerate wilting in the Bradford pear?

Yes, high temperatures encourage bacterial proliferation and hence wilting disease is more prevalent in warmer months.

Can wilting spread to other Bradford pear trees?

Yes, wilting is highly infectious and can quickly spread to nearby Bradford pear trees through various vectors.

Is wilting in the Bradford pear treatable?

Yes, wilting can be treated with non-pesticide and pesticide approaches, but prompt detection and action are crucial.

Can pruning prevent wilting in the Bradford pear?

Pruning can reduce the concentration of the disease but not completely prevent it. It's crucial to sanitize tools after use to avoid spread.

Can wilting bacteria survive in the soil?

Yes, the bacteria can survive in soil for long periods and infect Bradford pear trees planted later.

Is all wilting in the Bradford pear caused by the same bacterium?

While the primary cause is the Erwinia amylovora bacterium, other bacterial and abiotic factors can also contribute to wilting symptoms.
