Beneficial insects used in integrated pest management (IPM) can sometimes completely eliminate the need for crop chemicals, or at least reduce chemical spraying to a minimum.
One of the crucial factors in seedling production is achieving a high and uniform germination. A loss in germination of just a few percent translates into a similar reduction in profit.
Some farmers, especially at the end of winter, use seedlings for their cucurbit crops in an attempt to get an early-growth advantage and better prices.
As mentioned in one of my previous articles polystyrene seedling trays are made by heating small polystyrene beads in a mould; they expand to fill the mould and thereby form the tray.
When I mention seedlings in my articles, you may take it for granted that I’m referring to professionally grown seedlings in cavity seedling trays. The reason is that it is extremely difficult for the average farmer, let alone a new farmer, to grow seedlings successfully.
When the leaf miner first hit South Africa, the results were nothing short of devastating.
Iceberg lettuce has a good number of outer leaves, which help protect the head during transport and handling.
The African bollworm (Helicoverpa armigera) is normally a sporadic pest; it tends to arrive on lettuce plants in bursts, rather than gradually increasing in number.
One pest that every bean farmer knows is the African bollworm. This tends to appear sporadically, rather than building up its population gradually.
Fresh produce growers often try to plan production to capitalise on high prices.
Garlic (Allium sativum) can be grown in a wide range of soil types. What is more important is good fertility, as this crop has a modest root system.
The purpose of crop rotation is to prevent the build-up of a pest or disease to which a crop is susceptible. But there is more to rotation than merely switching.
