Weed control by insects is increasingly important, as chemical weed control (the use of herbicides) has an important impact on the environment and, consequently, on all organisms living there. The use of insects to control weeds thus represents an alternative to herbicides. The article presents the suppression of some widespread and persistent weeds in Europe with their natural enemies - insects. The following combinations presented below are: broad-leaved dock (<em>Rumex obtusifolius</em> L.) – <em>Gastrophysa viridula</em> (De Geer, 1775), curly dock (<em>Rumex crispus</em> L.) – <em>Apion violaceum</em> (Kirby, 1808), common ragweed (<em>Ambrosia artemisiifolia</em> L.) – <em>Ophraella communa</em> (LeSage, 1986) and <em>Zygogramma suturalis</em> (Fabricius, 1775), creeping thistle (<em>Cirsium arvense</em> (L.) Scop.) – <em>Cassida rubiginosa</em> (Müller, 1776), cleavers (<em>Galium aparine</em> L.) – <em>Halidamia affinis</em> (Fallen, 1807) and <em>Sermylassa halensis</em> (Linnaeus, 1767), common knotgrass (<em>Polygonum aviculare</em> L.) and black-bindweed (<em>Fallopia convolvulus</em> L.) – <em>Gastrophysa polygoni</em> (Linnaeus, 1758) and as the last one field bindweed (<em>Convolvulus arvensis</em> L.) – <em>Galeruca rufa</em>  (Germar, 1824) and <em>Tyta luctuosa</em> (Denis in Schiffmuller, 1775).

Rumex crispus L. is an invasive species widespread in our country and in particular in the region of North Bulgaria. It is characterized by high biological and ecological plasticity. Owing to its great reproductive potential, the weed has been assigned to the list of economically most important weeds in the country. With the purpose of studying the possibility of chemical weed control in noncropped areas with heavy natural background infestation with R. crispus L. and other dicotyledonous weeds, two field trials were carried out. A ready-to-use herbicide mixture 2,4-D 140.2 g/l-1 + Triclopyr 144 g/l-1, trade product Genoxon 3X (X0050), was tested at two doses of active ingredient, 3552 and 2842 ml/ha-1. It was found that: (1) population density of Rumex crispus L. can be successfully reduced by treatment at the stage of early stem formation; herbicide efficacy with 3552 and 2882 ml/ha-1 doses on the 21st day after treatment was 100% and 90.5%, respectively, at the end of vegetation 94.4 and 85.7%, respectively; (2) herbicidal efficacy was lower when R. crispus L. was treated at the 5 - 6 leaf stage, being 100 - 94.1% and 80 - 76.5% respectively for the indicated doses and time of recording; (3) at the studied doses the herbicide controlled both annual dicotyledonous weeds (Amaranthus spp., Chenopodium album L., Portulaca oleracea L.) and perennial dicotyledonous ones (Cirsium arvense L., Sonchus arvensis L., Convolvulus arvensis L., Carduus acanthoides L.), but it was not toxic to monocotyledonous weeds.

The preemergence efficacy of soil surface applications of aPhomopsis convolvulusgranular formulation to control field bindweed seedlings was compared with its efficacy when inoculum granules were incorporated in soil. In addition, the effect of different doses of soil-applied granules was also determined. Under controlled environment conditions, incorporation of the fungal granules resulted in aboveground biomass reductions between 88 and 96%, with no significant differences observed between incorporation depths of 1.5 and 3 cm. Granule applications on the soil surface were less effective, reducing aboveground biomass 40 to 83%. In a parallel field experiment conducted over two growing seasons, however, surface applications of inoculum granules resulted in greater weed control compared with soil incorporation of the granules. In spring and summer trials conducted in 1996, surface applications resulted in a 93 and 100% aboveground biomass reduction, respectively, whereas incorporated granules reduced biomass 62 and 97%. Similar trends were observed in 1997. Different soil-applied doses ofP. convolvulusdid not affect the level of weed control under both controlled environment and field conditions. In 1995 and 1996 field trials, all rates used (30, 20, and 10 g 0.25m−2plot) resulted in substantial (90 to 100%) field bindweed aboveground biomass reductions. Findings in this study indicate that under field conditions, preemergence applications of the bioherbicideP. convolvuluson the soil surface provide effective control of field bindweed.

Abstract There is interest in alternative weed control methods to herbicide use, especially among those interested in organic approaches. The use of microwave radiation as a weed control method appears to be a good alternative because it does not produce chemical residues in the environment. A study was conducted to determine the impact of plant age on weed control using microwave radiation. Ten weed species, representing monocots and dicots, were selected for this study: southern crabgrass (Digitaria ciliaris (Retz.) Koeler), dallisgrass (Paspalum dilatatum Poir.), false green kyllinga (Kyllinga gracillima Miquel), fragrant flatsedge (Cyperus odoratus L.), yellow nutsedge (Cyperus esculentus L.) common ragweed (Ambrosia artemisiifolia L.), white clover (Trifolium repens L.), pitted morningglory (Ipomoea lacunosa L.), henbit (Lamium amplexicaule L.) and field bindweed (Convolvulus arvensis L.). In general, weed species become more tolerant of microwave treatments as they increased in size, as 8 to 10 week-old plants were injured less than 4 to 6 week-old plants. Most grass species regrew when treated at 90 and 180 joules.cm−2 of microwave radiation. Pitted morningglory and common ragweed showed the highest susceptibility to microwave radiation among all treated weed species. The increase in a weed's biomass over time probably increases the amount of microwave radiation necessary for heating samples to the thermal threshold required for control. Index words: Nonchemical control, microwave, weed age, weed maturity, thermal weed control. Species used in this study: southern crabgrass (Digitaria ciliaris (Retz.) Koeler); dallisgrass (Paspalum dilatatum Poir.); false green kyllinga (Kyllinga gracillima Miquel); fragrant flatsedge (Cyperus odoratus L.); yellow nutsedge (Cyperus esculentus L.); common ragweed (Ambrosia artemisiifolia L.); white clover (Trifolium repens L.); pitted morningglory (Ipomoea lacunosa L.); henbit (Lamium amplexicaule L.); field bindweed (Convolvulus arvensis L.).

A field study was conducted to evaluate the compatibility of herbicide tank mixtures in winter wheat (Triticum aestivum L.) Sagittario cv. in 2017-2019. Weed Index (VI) and Crop Injury (CI) of three mixtures prominent was recorded with mesosulfuron-methyl plus 2.4-D ethylhexyl ester + florasulam (5.8% and 1.5%) followed by pyroxsulam + florasulam  + cloquintocet-mexyl plus 2.4-D dimethylamine salt (6.3% and 1.6%), and mesosulfuron-methyl + iodosulfuron-methyl-sodium plus bromoxynil + MCPA (7.1% and 0.0%), respectively. Weed Control Efficiency (WCE) was maximum with mesosulfuron-methyl + mefenpyr-diethyl plus 2.4-D ethylhexyl ester + florasulam so, Cirsium arvense (90%) heavily damaged; Avena fatua (98%), Avena sterilis (94%), and Papaver rhoeas (96%), Sinapis arvensis (95%) very heavy damaged (severe chlorosis and/or dead leaves); Galium aparine, Phalaris brachystachys, and Ranunculus arvensis were completely killed (100%, dead). Consequently, mesosulfuron-methyl + mefenpyr-diethyl plus 2.4-D ethylhexyl ester + florasulam herbicide mixture is recommended to provide weed control efficiency and wheat production safely. The compatibility of herbicides is necessary for sustainable weed management as it leads to reduced input costs, to prevent economic losses and to less pollution of the ecological environment. In addition, the conditions may require that the herbicides be applied with fungicides, insecticides or foliar fertilizers, and growers wish to know the safety of these mixtures. Therefore, studies on the compatibility of chemicals used in agriculture were considered to be needed.

Canada thistle [Cirsium arvense(L.) Scop.] and field bindweed (Convolvulus arvensisL.) were controlled in asparagus (Asparagus officinalisL. ‘Mary Washington’) fields by repeated applications of dicamba (3,6-dichloro-o-anisic acid) at 0.6 kg/ha or 2,4-D [(2,4-dichlorophenoxy)acetic acid] + dicamba at 1.1 + 0.3 or 1.1 + 0.6 kg/ha. Applications of 2,4-D + dicamba at 1.1 + 0.6 kg/ha in early May and again in mid-June controlled 97% of the Canada thistle in asparagus fields. A third application about August 1 was required to give similar control of field bindweed. Rates of dicamba exceeding 0.6 kg/ha injured the asparagus.

Field bindweed is extremely susceptible to aminocyclopyrachlor compared to other weed species. Laboratory studies were conducted to determine if absorption, translocation, and metabolism of aminocyclopyrachlor in field bindweed differs from other, less susceptible species. Field bindweed plants were treated with 3.3 kBq14C-aminocyclopyrachlor by spotting a single leaf mid-way up the stem with 10 µl of herbicide solution. Plants were then harvested at set intervals over 192 h after treatment (HAT). Aminocyclopyrachlor absorption reached a maximum of 48.3% of the applied radioactivity by 48 HAT. A translocation pattern of herbicide movement from the treated leaf into other plant tissues emerged, revealing a nearly equal aminocyclopyrachlor distribution between the treated leaf, aboveground tissue, and belowground tissue of 13, 14, and 14% of the applied radioactivity by 192 HAT. Over the time-course, no soluble aminocyclopyrachlor metabolites were observed, but there was an increase in radioactivity recovered bound in the nonsoluble fraction. These results suggest that aminocyclopyrachlor has greater translocation to belowground plant tissue in field bindweed compared with results from other studies with other herbicides and other weed species, which could explain the increased level of control observed in the field. The lack of soluble metabolites also suggests that very little metabolism occurred over the 192 h time course.
