Sweetcorn Research

Sweetcorn became a popular vegetable in the 1960s which is a sweet version of maize. Several varieties are available, some have white kernels and others have a mix of yellow and white kernels. Varieties differ in sweetness, and recently super-sweet varieties have become available.

In 2015 the total tonnage grown was 69,000 tonnes.

A Smutty Story
Date 2017-03-20 11:24:24
This article was commissioned as a 'review' of head smut with particular reference to sweetcorn. A search of literature published over the past 30 years revealed over 200 scientific papers on head smut of maize, but only 10 specifically on head smut of sweetcorn. Because the fungus does not discriminate between hosts, the information relating to maize is equally applicable to sweetcorn and popcorn. In preparing the article I have utilised information from published papers, a number of 'classic' texts on smuts and drawn on my own experience of over 10 years research on the biology and control of smut fungi in cereals and grasses in Australia, Canada and New Zealand

Greasy Cutworm Caterpillars in Seedling Maize and Sweetcorn

Six replicated field trials were undertaken to evaluate Fastac (alphacypermethrin, 10% EC), Karate Zeon (lambdacyhalothrin, 25% capsule suspension) and Sumi-Alpha (esfenvalerate, 5% EC) applied as broadcast sprays in combination with pre-emergence herbicides, for the control of greasy cutworm (Agrotis ipsilon aneituma) caterpillars in seedling maize and sweetcorn (Zea mays).
