High Yields

Phaseolus vulgaris (beans; green beans) as a food of high nutritional value occupies an important place in the human diet. In addition to all the basic growing conditions, one of the key requirements for achieving high yields is successful weed control. Weeds such as Amaranthus retroflexus, Chenopodium album, Datura stramonium, Abutilon theophrasti, Xanthium strumarium, Cirsium arvense, Ambrosia artemisiifolia, Sorghum halepense and others appear as the most dominant species in our agroecological conditions. The application of the concept of integrated weed control implies the application of all available measures (crop rotation, proper and timely tillage, application of herbicides, etc.). Although there is a wider range of registered herbicides for weed control in beans and green beans in the world, preparations based on active substances: clethodim, quizalofop-P-tefuril, imazamox and bentazone have been registered in Serbia.

The Right

The damage from the present weeds in maize crop is shown by the reduction of yield in almost every year and their suppression is completely economically justified. The right selection of herbicides mostly depends on the presence of dominant weed species and the time of application. The paper presents the distribution and existence of economically harmful, invasive and quarantine weed species (Abutilon theophrasti, Agropyrum repens, Amaranthus retroflexus, Ambrosia artemisiifolia, Capsela bursa-pastoris, Chenopodium album, Chenopodium hybridum, Cirsium arvense, Convolvulus arvensis, Datura stramonium, Avena fatua, Calystegia sepium, …) on ten locations of maize crops in the Nisava district. Estimation of the species presence was done in two shootings (May and August) on scale 1-4 (1 - species appears individually and occupy up to 5% of the surface, 2 - appears and occupies 5-25% of the surface, 3 - appears often and occupies 25-50% of the surface, 4 - the species prevails over the cultivated plant and occupies over 50% of the surface).

Goal. To establish the species composition of weeds, their dominant role and determine the type and level of weediness of soybean crops for cultivation in a fixed nine-course stationary, fallow-crop-row rotation and in monoculture in the eastern part of the Forest-Steppe of Ukraine. Methods. The research was conducted by route surveys in field experiments. Results. According to the research of 2011—2017, 30 species of weeds and contaminants were found in soybean crops after winter wheat as forecrop in the stationary crop rotation (spring early and late were 60%, winter and biennial were 17%, perennial were 23%), and 18 species (spring early and late were 72%, wintering and biennial were 6%, perennial were 22%) were found for cultivation in monoculture. They belonged to 16 families, the families Asteraceae (9 species), Poaceae (5 species) and Polygonaceae (5 species) were the most represented. The main weeds in soybean crops in crop rotation and monoculture were Echinochloa crus-galli (L.) Roem. et Schult., Chenopodium album L., Cirsium arvense (L.) Scop. and Panicum miliaceum L. In addition to these weeds for growing soybeans in crop rotation were present Setaria glauca (L.) Beauv., Amaranthus retroflexus L., Solanum nigrum L., Polygonum lapathifolium L., Sonchus arvensis L., Convolvulus arvensis L., and in monoculture were Ambrosia artemisiifolia L. and Xanthium strumarium L. Xanthium strumarium L. was the most dominant in the monoculture (43%), and Setaria glauca (L.) Beauv was subdominant in crop rotation (57%), and Echinochloa crus-galli (L.) Roem. and Schult. was subdominant in monoculture (57%). Six complex types of weeds were formed in soybean crops, cereal-dicotyledonous-dicotyledonous-root-sprouting and dicotyledonous-grass-annual-grass-root-sprouting prevailed. For cultivation in crop rotation cereal annual species predominated, and dicotyledonous annuals predominated in monoculture. At the same time, the monoculture had a higher level of weeding than crop rotation, or it was equivalent. Conclusions. The species composition of weeds in soybean crops in fallow-crop-row rotation and monoculture differs significantly, which should be taken into account by the agronomic service of farms when developing methods of their control.

Imazaquin {2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid} was evaluated in the field for weed control in flue-cured tobacco (Nicotiana tabacumL.) during 1983 and 1984. The 75 DG formulation of imazaquin was used at 0.28 and 0.42 kg ai/ha. Methods of application were: preplant incorporated, over the top immediately after transplanting, postbed incorporated, and early postemergence. Imazaquin controlled 90%, or better, of common lambsquarters (Chenopodium albumL. # CHEAL), common ragweed (Ambrosia artemisiifoliaL. # AMBEL), redroot pigweed (Amaranthus retroflexusL. # AMARE), spiny amaranth (Amaranthus spinosusL. # AMASP), ivyleaf morningglory [Ipomoea hederacea(L.) Jacq. # IPOHE], sicklepod (Cassia obtusifoliaL. # CASOB), and prickly sida (Sida spinosaL. # SIDSP) with all application methods except early postemergence. It controlled 80 to 89% of large crabgrass (Digitaria sanguinalisL. # DIGSA) by the soil-applied methods. Postemergence applications of imazaquin controlled common ragweed, pigweed spp., ivyleaf morningglory, prickly sida, and sicklepod. Imazaquin was less effective postemergence on lambsquarters and large crabgrass. Tobacco tolerated use of imazaquin by all methods of application except preplant incorporation.

Field studies were conducted at Dekalb, Urbana, and Brownstown, IL, in 1996 and 1997 to evaluate corn (Zea mays) injury and weed control from preemergence applications of RPA 201772 alone and tank-mixed with metolachlor, atrazine, or both. No significant corn injury from RPA 201772 was observed at any time for all experiments. Giant foxtail (Setaria faberi) control at 60 days after treatment (DAT) was variable and ranged from 47 to 93% for RPA 201772 applied alone at 105 g ai/ ha. Giant foxtail control of at least 90% was observed by applying metolachlor at 1,120 g ai/ha with 105 g/ha RPA 201772. The addition of atrazine at either 1,120 or 1,680 g ai/ha improved control of giant foxtail compared with RPA 201772 applied alone at 105 g/ha in two of the six studies. RPA 201772 applied at 105 g/ha controlled at least 88% of velvetleaf (Abutilon theophrasti), Pennsylvania smartweed (Polygonum pensylvanicum), and smooth pigweed (Amaranthus hybridus). RPA 201772 controlled 88% or less of common waterhemp (Amaranthus rudis), common ragweed (Ambrosia artemisiifolia), and common cocklebur (Xanthium strumarium). Control of these three species was 92% or greater with RPA 201772 plus atrazine. Control of common lambsquarters (Chenopodium album) was at least 96% with RPA 201772 applied alone at any rate in four of the six studies. However, common lambsquarters control was 68 and 77% for RPA 201772 applied alone at 105 g/ha at Urbana and Brownstown in 1997, respectively, where high common lambsquarters densities were prevalent. Under these conditions, the addition of atrazine to RPA 201772 at 105 g/ha improved control of common lambsquarters. RPA 201772 has excellent potential to provide consistent control of velvetleaf compared with atrazine. In contrast, these studies indicate RPA 201772 may provide inconsistent control of certain weed species in different environments. In order to achieve consistent control of a broad spectrum of weed species, RPA 201772 must be combined with other herbicides.

Abstract. The purpose of the work is to establish the effectiveness of weed in control in crops of grain sorghum with herbicides of soil and leaf action. Scientific novelty. For the first time in sorghum crops for weed control, effective combinations of soil and leaf herbicides have been identified. Methods. Experiments were carried out on the black soils of steppe zone Ukraine. Research methods are generally accepted. The control options were herbicide-free and weed-free. Results. At tillering stage the number of weeds in sorghum crops reached 141 pieces/m2 and their air-dry weight was 218 g/m2. Green amaranth (Amaranthus retroflexus), fat hen (Chenopodium album), field mustard (Sinapis arvensis), ragweed ragweed (Ambrosia artemisiifolia), barnyard grass (Echinochloa crus-galli), bristlegrass (Setaria viridis) were dominant in the crops. The use of foliar-applied herbicides such as Agritox (1 l/ha), Ballerina (0.4 l/ha), Dialen Super (0.7 l/ha) in the stage of three-five leaves and a pre sowing soil-applied herbicide Primextra Gold (3 l/ha) ensured the maximum reduction of weed infestation of grain sorghum crops. The number of weeds with the use of these herbicides decreased by 10.4–19.7 times, and their weight decreased by 4.1–4.8 times in comparison with the options without the use of weed control measures. The conditions for plant growth and development were improved due to the reduction of weed infestation of grain sorghum crops. The growing period of the crop reduced from 125 to 114 days, the height of plants increased by 19–21 cm and their weight increased by 2.7–2.8 times. The sorghum grain yield reached 6.32–6.34 t/ha, which was higher than with the options without the use of weed control measures by 4.01–4.30 t/ha or 3.0–3.1 times. The same results were obtained in production conditions.

A field trial was conducted in Domokos region, in central Greece with Helianthus annuus, hybrid ‘LG 5658’ in order to evaluate the effects of different N fertilization and weed control methods on sunflower yield and weed flora. ANOVA showed that the interaction of fertilization and weed control had a significant effect on grain yield. Moreover, this study revealed that the density of the common weeds Amaranthus retroflexus, Abutilon theophrasti, Xanthium strumarium and Echinochloa crus-galli was increased by 60, 40, 33 and 23% in the plots of high N rate without any herbicide use. On the contrary, weeds like Datura stramonium and Convolvulus arvensis were not significantly affected by fertilization. This different responsiveness of the several weed species could be further exploited through programs of integrated crop and weed management. Moreover, our findings related to the differences in herbicide efficacy resulting from different N levels may alter weed flora and explain possible weed control failures.

In field studies, bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2,2-dioxide] was applied as postemergence sprays over the top of weeds and soybeans[Glycine max(L.) Merr.]. Bentazon at 0.84 to 1.68 kg/ha applied as an early postemergence treatment controlled wild mustard[Brassica kaber(DC.) L.C. Wheeler var.pinnatifida(Stokes) L.C. Wheeler], common ragweed (Ambrosia artemisiifoliaL.), velvetleaf (Abutilon theophrastiMedic.), Pennsylvania smartweed, (Polygonum pensylvanicumL.), common cocklebur (Xanthium pensylvanicumWallr.), and wild common sunflower (Helianthus annuusL.). Pigweeds (Amaranthussp.) were controlled by applications in the three true-leaf stage but became more resistant at later stages. Control of common lambsquarters (Chenopodium albumL.) was erratic. The optimum time for controlling weeds with bentazon was around the first trifoliolate stage of soybeans. Rainfall within several hours after treatment reduced weed control. Eight yield studies, two of which included eight cultivars, were conducted on weed-free soybeans. In none were yields reduced significantly by bentazon at 3.36 kg/ha (the highest rate studied). Eight yield studies were conducted on soybeans infested with common cocklebur or velvetleaf. Weed control was generally excellent with 0.84 kg/ha of bentazon. Where infestations were sufficient to reduce yields, bentazon treatments increased the yields to levels generally comparable with those of the handweeded checks. One exception was an application of bentazon to soybeans growing in a low area that was periodically flooded by heavy rains. In that experiment the benefit of controlling common cocklebur was offset by bentazon injury to the soybeans, and yields from the treated plots were about the same as those of the weedy check.
