CONVISO® ONE

Beet crops are slow growing and are very susceptible to weed competition during establishment. Fast growing weeds can swiftly outcompete beet crops, especially in the first 8 weeks of establishment. To maximise beet crop yields and quality it is vital that weed competition is eliminated during this early stage.

The CONVISO SMART beet growing system is an innovative approach that revolutionises controlling weeds by allowing CONVISO SMART cultivars to be treated with CONVISO ONE, a very effective, broad-spectrum grass and broad leaf herbicide.

The CONVISO SMART system comprises two elements: CONVISO SMART sugar and fodder beet cultivars bred and marketed by KWS and CONVISO ONE, a broad-spectrum herbicide specifically developed by Bayer. CONVISO ONE is only available as part of the CONVISO SMART system from KWS.

The CONVISO SMART system has significantly simplified weed control for sugar and fodder beet. Two applications of CONVISO ONE plus Partner (adjuvant) applied with a 10-14 day interval will provide very high levels of weed control. The first application is applied when the indicator weed (normally fathen) reaches 2-4 true leaves which ensures weed competition is removed early in the life of the beet crop.

A simple programme of two applications of CONVISO One controls a broad weed spectrum including ryegrass and broadleaf weeds such as mallow in CONVISO SMART sugar beet cultivars
CONVISO ONE offers a convenient approach to weed control in CONVISO SMART sugar and fodder beet cultivars with two applications applied 10-14 days apart providing excellent weed control
CONVISO ONE exhibits excellent crop safety and can be applied from 2 true leaves of the crop
Applying CONVISO ONE in the early stages of crop establishment removes weeds before they can significantly compete with the crop
The low dose of CONVISO ONE minimises packaging

Crop	CONVISO SMART cultivars of sugar and fodder beet
Weeds controlled	Grass and broad-leaved weeds
Product type	Herbicide – Group 2
Active ingredient	Foramsulfuron 50 g/L Thiencarbazone-methyl 30 g/L
Formulation type	Oil dispersion
Pack size	1 L
Application rate/timing	0.5 L/ha in mixture with 0.5 L/ha Partner applied from the beet two true leaf stage and when the indicator weed (fathen) is at 2-4 true leaves. If fathen isn’t present choose an alternative indicator weed and apply the first application of CONVISO ONE at 2-4 true leaves of this weed. Apply a second application of CONVISO ONE 0.5 L/ha in mixture with 0.5 L/ha Partner 10-14 days after the first application. Apply the second application even if weeds seem controlled as it delivers greater residual control.
Mixing	Ensure spray equipment is thoroughly cleaned before use as per the label instructions. Half fill the spray tank with water and turn on the agitation system. Add the required amount of CONVISO ONE. Add the remaining water and any tank mixture partners. Add the required amount of Partner (supplied). Maintain agitation until spraying is complete. Follow the tank cleaning instructions detailed on the CONVISO ONE label.
Application volume	Apply CONVISO ONE plus Partner in 200 to 300 litres of water per hectare.
Compatibility	CONVISO ONE plus Partner can be applied in mixture with non-ALS (Group 2) herbicides.
Withholding period	70 days
Following crops and crop failure	For details on the required plant-back periods for following crops please contact your Bayer Crop Science representative for the latest information.

Annual Poa

Poa annua

Annual poa (Poa annua), also known as annual meadow grass, is a fast growing annual grass found throughout New Zealand in a wide range of crops. While individual plants tend to be small, populations of this grass weed tend to be large and they then compete for light, nutrients and water. Poa annua is best identified by the boat shaped tips to its leaves and the two parallel veins (often referred to as tramlines) that can be seen if the leaf blade is bent backwards. Germination takes place throughout the year and is set very quickly meaning populations soon increase.

Fathen

Chenopodium album

Fathen (Chenopodium album), pronounced fat-hen and sometimes called fat hen, is one of the most serious weeds of cropping throughout New Zealand. It is an annual that germinates in the spring and early summer and then dies off in the autumn with frosts. Fathen is an extremely vigorous weed that can quickly outcompete and smother crops. An upright plant that can grow to 2 m tall and is a prolific seeder.

Ryegrass - Annual

Lolium multiflorum

Annual ryegrass (Lolium multiflorum) is an important cultivated grass species which becomes a very competitive weed when growing in cultivated crops. Generally germinating at the same time as the crop it grows quickly and competes aggressively for space, light, nutrients and water. Uncontrolled annual ryegrass will significantly reduce yields. To identify look for young plants between the crop rows, young plants are upright and the leaves have prominent veins. As plants get bigger the leaves are shiny underneath and these stand out, especially on breezy days. Later, when in ear look at the seedhead as ryegrasses have one edge of the seed against the axis which means the flat side of the seed is visible.

Broad-leaved Dock

Rumex obtusifolius

Broad-leafed docks (Rumex obtusifolius) grow prolifically throughout New Zealand. This is the most common dock weed found around farmyards, in damp arable & pasture land, wasteland and gardens.

The leaves are very large and broad (up to 35 cm long and 15 cm wide) hairy underneath, and have long stems. The plant can grow to 1 m tall. Flowers appear from July to April and are usually small, green (sometimes red) and inconspicuous, carried above the leaves in clusters. The root is a strong thick perennial taproot, enabling easy regrowth. Seeds are a reddish brown.

Mallow - Giant

Malva spp.

Mallow (Malva spp.) is a term used to describe a group of species. Several of them are difficult to tell apart. Generally, they are described as short-lived perennials meaning the same plant can continue growing for a number of years if conditions favour good growth. If not controlled properly in the first year after germination, control can become more difficult. Generally, older and / or larger perennial plants continue to grow and develop a larger root systems and hardier stems, making the use of higher rates of effective foliar herbicides and good coverage necessary.

Shepherds Purse

Capsella bursa-pastoris

Shepherd's purse (Capsella bursa-pastoris) is a rosette annual with distinctive flower stems that grow to 30 cm high. It is very common throughout New Zealand in cultivated soil and is conspicuously present in the winter although it can germinate at any time through the year.

Wireweed

Polygonum aviculare

Wireweed (Polygonum aviculare) is a widespread annual with wiry, trailing stems that form mats up to 1 m in width. Wireweed (or wire weed) prefers to germinate in wet soils so it is problematic in winter and in spring sown crops as it can be very competitive and smother crops. Once larger than a seedling, is difficult to control, with selective herbicides in crops.
