KWS SAAT SE and Bayer CropScience AG are jointly developing and commercializing an innovative system of weed control in sugar beet for the global market under the name of CONVISO SMART. The technology is based on the breeding of sugar beet cultivars that are tolerant to herbicides of the ALS-inhibitor-class with a broad-spectrum weed control. This will give farmers a new opportunity to make sugar beet cultivation easier, more flexible in its timing and more efficient. The use of CONVISO, as new herbicide in sugar beet, will make it possible to control major weeds with low dose rates of product and reduced number of applications in the future. The tolerance is based on a change in the enzyme acetholactate synthase, which is involved in the biosynthesis of essential amino acids. This variation can occur spontaneously during cell division. During the development, sugar beets with this spontaneously changed enzyme were specifically selected and used for further breeding of CONVISO SMART cultivars. As such, these varieties are not a product of genetic modification. Field studies with CONVISO SMART hybrids showed complete crop selectivity and a broad and reliable efficacy against a large range of major weeds. The bio-dossier for an EU-wide registration of CONVISO was submitted in April in 2015. The variety inscription process is in preparation in different countries. The system CONVISO SMART is scheduled to be available to farmers in 2018 at the earliest.

Major Target

ABSTRACTHerbicides mixtures are used in many situations without the adequate knowledge related with the effect on major target weeds. The objective of this study was to evaluate the effects of different herbicides mixtures used in irrigated rice in order to establish the adequate combinations for the prevention and management of herbicide resistance in barnyardgrass (Echinochloa crus-galli). Three experiments were performed at field conditions with all major post-emergent herbicides used in irrigated rice in Brazil. The first experiment was performed with barnyardgrass resistant to imidazolinone herbicides and herbicides applied at label rates. The second and third experiments were performed with barnyardgrass resistant and susceptible to imidazolinone herbicides applied at doses of 50 or 75% of the label rates. The occurrence of additive, synergistic and antagonistic effects was identified at 18, 18 and 64%, respectively, among the total of 50 different associations of herbicide and rates evaluated. In general, the mixture of ACCase inhibitors with ALS inhibitors, quinclorac, clomazone + propanil or thiobencarb resulted in antagonism. Sinergic mixtures were found in clomazone with propanil + thiobencarb, profoxydim with cyhalofop-butyl or clomazone, and quinclorac with imazapyr + imazapic, bispyribac-sodium or cyhalofop-butyl. The mixtures of quinclorac with profoxydim were antagonic. Rice grain yield varied according to the efficiency of weed control. Seveveral mixtures were effective for imidazolinone resistant barnyardgrass control.

Hand Weeding

A field investigation was carried out to evaluate the effect of herbicides and their mixtures on weeds in wheat (<italic>Triticum aestivum</italic> L.) cv. PBW-343. Minimum weed density per m2 and weed dry weight (5.13 and 17.31g) was recorded with sulfosulfuron at 25g ha−1 followed by clodinofop at 60g + metsulfuron methyl at 4g ha−1 (5.19 and 18.45g), metribuzin at 200gha−1(5.85 and 25.98g), pendimethalin at 1000g fb 2,4-Dat400g ha−1 (6.49 and 31.73g) and hand weeding twice(7.01 and 35g), respectively. Also, maximum weed control efficiency was recorded under sulfosulfuron at 25g ha−1 (83.85%) followed by clodinofop at 60g + metsulfuron methyl at 4g ha−1 (83.17%) and metribuzin at 200g ha−1 (75.85%), respectively. All the weed control treatments recorded significantly higher harvest index than the weedy check (40.24). Among various herbicidal treatments, application of clodinofop at 60g + metsulfuron methyl at 4g ha−1 recorded highest harvest index (41.91) followed by sulfosulfuron at 25 gha−1 (41.83) and pendimethalin at 1000g fb2,4-Dat 400gha−1 (41.25) respectively. The harvest index recorded under clodinofop at 60g + metsulfuron methyl at 4g ha−1 and sulfosulfuron at 25 g ha−1 was significantly at par with weed free (42.06).

A field experiment was conducted at the Rajasthan College of Agriculture, MPUAT, Udaipur during Kharif season 2015 and 2016 to adjudge the efficacy of different herbicide and herbicide mixtures against weeds in soybean. Monocot weeds were predominant (55.15%) in the experimental field compared with dicot weeds (44.85%). However, Echinochloa colona (41.56%) and Trianthema portulacastrum (33.16%) were predominant in soybean but, other weeds (Cyperus rotundus, Cynodon dactylon, Commelina benghalensis, Digera arvensis, Amaranthus viridis, Physalis minima, Corchorus spp.) were also present at 60 DAS. Among different weed control treatments, post-emergence and tank mix combination of propaquizafop + imazethapyr (75+75 g ha-1) and imazethapyr + quizalofop-ethyl (75+60 g ha-1) at 21 DAS were most effective in respect of reducing weed density, weed biomass, nutrient removal by weed and promote yield attributes and yield and quality of soybean as compared to rest of weed control treatment.
