Cotton bollworm

When to look

Together with the silver Y moth, it infested soya from the budding stage to pod ripening.

No rate and no spray timing here: both come from the label and the register.

Generations a year

It develops in two generations, in places in three (Kherson, Zaporizhzhia and Vinnytsia oblasts), where the third generation overlapped with the second.

Favourable conditions

Warm, moderately humid weather in spring and summer and the presence of nectar plants during moth flight favour development. Under such conditions, hotspots of increased numbers are possible.

Where it is found

It occurs in all regions of the country except Polissia. Together with the silver Y moth and the cabbage moth, it was among the most widespread leaf-feeding noctuid moths.

Every fact rests on a quote from its source, and each quote was checked against the page it is printed on.
