New generation broccoli is now available for the coming season, as well as our trusted varieties from last season. These include Alamo, Anaconda, Blackjack, Brutus, Cassius, Diablo, El Camino, Spinks and Viper.

Currently the new varieties Alamo, Brutus, Diablo and El Camino have good colour and smooth dome heads. Of the broccoli range, we have a variety to suit all harvest seasons, including winter, spring and early summer, in different climates around Australia.

Viper, El Camino and Alamo are fastest for their chosen time slots. With Cassius having strong erect plant and thick stems, Blackjack with excellent performance for spring harvest and Spinks showing excellent weight with no side shoots, Lefroy Valley has a broccoli for every market.

Contact your local office or sales representative for more information.

ICON is a brand new gourmet which has shown outstanding potential in WA in all production slots, in Southern Queensland throughout the summer production slot and, and in the winter harvest slot in N Queensland. ICON has a vigorous bush and yields of medium large 150g-190g, firm fruit with a small, neat calyx scar. ICON has a good genetic resistance package listed below but the vigorous bush allows it to continue to yield well even under high leaf disease pressure. HR: Mi, Mj, Ma, Fol1-3, TYLCV, TSWV, Mi - Root knot nematode (Meloidogyna incongnita), Mj - Root knot nematode (Meloidogyna juncea), Ma- Root knot nematode (Meloidogyna arenaria) Fol1-3 - Fusarium wilt races 1-3 (Fusarium oxysporum f.sp.lycopersici), TYLCV - Tomato Yellow Leaf Curl Virus, TSWV - Tomato Spotted Wilt Virus

Cowpea mild mottle virus (CPMMV) is a member of the Carlavirus group of plant viruses. Unlike other Carlaviruses, which are aphid transmitted, CPMMV is transmitted by the silver leaf whitefly. CPMMV has a very wide geographical range, occurring mainly in countries where grain legumes are grown. CPMMV was first detected in Australia in 2016 on bean and soybean in Queensland. French bean, soybean and cowpea are the most commonly infected, with other hosts including mung bean, asparagus bean, adzuki bean and lima bean. A wide range of symptoms can develop including leaf mottling and mosaic. Seed pods may be deformed and surface discolouration may be present. Also referred to as angular mosaic because of the yellow, angular leaf spots.

A high-value herb, basil has aromatic leaves that can be used in cooking or freshly eaten. Production can be greatly diminished by infections of basil downy mildew (BDM).

Doux - literally translating to "Sweet" is s Kale variety that is faster growing and higher yielding than traditional curly kale. The flavour is also milder and sweeter. Plants have attractive, upright, rather dark green leaves. Very vigorous, as it matures the leaves become slightly more serrated than normal kale (Brassica napus). Very versatile, makes attractive salad crops in many different areas. IR: Hb

The history of the carrot can be traced back 5000 years, originating in Afghanistan, and then over the centuries being carried along the trade routes of Arabia, Africa, and Asia, to be sold in regions anxious to cultivate new and productive plants. Even in the early days there were many varieties of carrots, coming in an assortment of colours - purple, white, black, and red but, surprisingly, not orange!

Both the ancient Greeks and the Romans were familiar with carrots, although these early varieties were not the sweet, succulent orange carrots that are grown today. Early carrots were typically not often eaten as food by the Greeks, but were used for medicinal purposes. The Romans were known to have eaten both raw and cooked carrots accompanied with an olive oil dressing containing different herbs.

Carrots were well-known to 16th century botanists and writers, who described red and purple varieties in France, and yellow and red varieties in England. The Dutch cross-bred the yellow and red carrot to produce a variety that was the emblematic colour of the House of Orange. This carrot quickly became popular and was further developed to become the sweet, succulent orange carrot which is the most recognized colour of carrot used throughout the world today.

White Blister (White Rust) on Broccoli - Albugo candida (Ac)

White rust is common on Brassica oleracea (broccoli, Brussels sprouts and cabbage) but also mustards, radish, horseradish and weeds from the Brassica family. In Australia the greatest commercial problem occurs with broccoli. The age at which the plant is infected determines the degree of economic loss. When infection occurs in seedlings, the plants are likely to die but the direct effect of infections later in the crop is generally not as severe. The difference in broccoli is that when lesions occur on fully developed heads, significant economic yield loss can result. Symptoms can occur on different stages of development, affecting cotyledons, true leaves and florets (heads). On cotyledons, the effect...

TOMATO & WATERMELON GRAFTING In vegetable production one of the consequences from continuous cropping is the buildup of soil-borne pathogens such as Fusarium wilt, Bacterial wilt and Nematodes. Grafting of vegetable plants is becoming an effective option to assist to overcome these problems. In addition to disease resistance, grafting of a vigorous rootstock to traditional vegetable cultivars can increase yield and improve water and nutrient uptake. The use of a vigorous rootstock will increase the vigour of the plant due to the stronger root system. This results in improved leaf area and stem diameter and enables the plant to continue growing under cool conditions and extends the productive life of the crop. The use of chemicals against soil diseases can be reduced. Stronger plants reduce the chance of successful attacks by secondary parasites. A graft combination of a vigorous scion on an equally vigorous rootstock can reduce the amount of fertilizer required. Field experience has shown on tomatoes,...

Sweet corn breeders have drawn heavily on the work done by field corn breeders, and have found that in many respects the two crops are essentially alike; in others, however, they differ considerably. Sweet corn, like maize is a hybrid crop requiring at least two parents to create the resultant progeny. Sweet corn breeders focus on a greater number of what can be termed subjective traits such as pericarp tenderness, eating quality and overall ‘bite’ – the experience of what it is like to actually bite into an ear of corn. These are quite complicated traits and ones that are hard to measure with any sort of mechanical device. The simplest method of determining these traits is to just take a bite of cob! The similarity with field corn is more in relation to the agronomic traits such as disease resistance, standability...
