I have whitefly on my sprout leaves, is this the same type that attacks indoor plants, and if not, how do I control them.

The species of whitefly on brassicas is a much hardier strain than that which lives under glass, and will survive the hardest of winters, and it is just as difficult to control.

Fortunately, it doesn't do as much damage as glasshouse whitefly.

To control them, apply two or three sprays of insecticide when you first see them.

It is advisable to alternate varieties of pesticides to cater for the possibility of the aphid developing an immunity to one variety.
