Many problems including root feeding insects such as rantipole fofa le fofa motso oa k'habeche are better managed by insect proof mesh than pesticides and the extra shelter leads to better plants and heavier crops.

Stretching mesh, even by placing over hoops, can widen the gaps and reduce efficacy. Check manufacturer’s instructions. The edges of the mesh are best buried under at least 5cms of soil.

Leha ho le joalo horticultural fleece can exclude invertebrates very effectively, it is much less durable and can be easily damaged when removed for weed control. Fleece can also raise temperatures and humidity to levels that might be undesirable.

Phapanyetsano ea lijalo should be practised, as some invertebrates can get through the mesh and might persist until the following year, ready to multiply when the same crop is planted and the mesh replaced.

Boea ba boea should be used where crops need to be provided with extra warmth or frost protection.

Insect proof mesh may last five to ten years but unfortunately cannot be easily recycled. However, local recycling facilities should be checked. Insect netting made from biodegradable plant starch is now available from Andermatt, e fana ka khetho ea eco-friendly ho balemi ba lirapa. 

Khetho ea sehlahisoa

Insect-proof mesh is offered in pre-cut sizes, a variety of widths and any length can be ordered ‘off the roll’. The larger the sheet and the closer it is to manufactured sizes the less it costs per square metre.

Although theoretically capable of penetrating mesh, mammals and larger birds seldom do, so there is rarely any need to add further protection such as bird netting. However, this size is unreliable in excluding small insects such as hoaba, maleshoane, moepong oa lekhasi la allium le leek moth.
