This critical situation underscores the need for alternative, environmentally friendly pest management strategies. In this context, an experiment was conducted to investigate the biology, life table, and population parameters of the generalist predator <em>Apertochrysa astur</em> Banks (Neuroptera: Chrysopidae) on three aphid species: Aphis craccivora (Koch), <em>Brevicoryne brassicae</em> (Linnaeus), and <em>Lipaphis erysimi</em> (Kaltenbach). <em>A. astur</em> achieved higher survival and shorter developmental durations when fed on <em>A. craccivora</em> compared to the other aphids. The mean generation time (<em>T</em>) was shortest on <em>A. craccivora</em> (53.79 days), followed by <em>B. brassicae</em> (57.78 days) and <em>L. erysimi</em> (59.58 days). Values of intrinsic rate of increase (<em>r</em>) and finite rate of increase (<em>λ</em>) were highest on <em>A. craccivora</em> (0.0868 days⁻¹ and 1.0896, respectively), indicating superior population growth potential. Predation potential was also highest on <em>A. craccivora</em>, with net predation rate (<em>C</em>_<em>0</em>) reaching 349.13 preys/individual, and higher finite (<em>ω</em> = 127.44 preys) and stable (<em>φ</em> = 116.99 preys) predation rates than on <em>B. brassicae</em> and <em>L. erysimi</em>. The results confirm that while <em>A. astur</em> can complete its life cycle on all three aphid species, <em>A. craccivora</em> supports optimal development, reproduction, and predation performance.

The study assessed the impact of residue mulch and various pre-emergence (PRE) and post-emergence (POST) herbicides on mungbean. In both years, mungbean yield was improved with <strong>imazethapyr at 100 g ai ha⁻¹</strong> (by 74–78 %) and <strong>pendimethalin at 750 g ai ha⁻¹</strong> (by 69–74 %) applied as pre-emergence treatments, as well as with <strong>propaquizafop at 100 g ai ha⁻¹</strong> (by 68–76 %) and <strong>quizalofop-ethyl at 50 g ai ha⁻¹</strong> (by 63–64 %) applied as POST treatments, achieving over 75 % weed control compared with the nontreated control. A ready mixture of clodinafop + sodium acifluorfen (165 + 80 g ai ha⁻¹) applied POST resulted in 95 % and 96 % higher yields in 2022 and 2023, respectively, compared with the nontreated control by providing excellent weed control (&gt;90 %). Wheat residue mulch (6 t ha⁻¹) increased mungbean yield by 59 % and 73 % in 2022 and 2023, respectively, compared with the nontreated control, by effectively reducing weed biomass. Pre-emergence herbicide (flumioxazin 250 g ai ha⁻¹, imazethapyr 100 g ai ha⁻¹, pendimethalin 750 g ai ha⁻¹, and pyroxasulfone 127 g ai ha⁻¹) treatments supplemented with wheat straw mulch did not provide an additional advantage for yield when compared to these herbicide treatments without mulch. Halosulfuron at 67 g ai ha⁻¹ applied POST initially caused the crop's toxicity, later recovered and thus resulted in improved yield by 27 % and 42 % in 2022 and 2023, respectively, compared with the nontreated control. These results suggest that pre-emergence herbicides such as imazethapyr and pendimethalin, and POST herbicides such as clodinafop + sodium acifluorfen, propaquizafop, and quizalofop-ethyl can be used in mungbean as a herbicide rotation program for sustainable weed control. Further, these results suggest that residue mulch can be used for effective weed control in the organic production of mungbean.

The main objective of this study was to compare the impact of different ALS-inhibiting residual herbicides on growth of oil-seed rape (<em>Brassica napus</em> L. subsp. <em>napus</em>) and sugar beet (<em>Beta vulgaris</em> L.) in alkaline soil. In this regard, three experiments were conducted in Prague, Czech Republic, during 2021–2023. In spring, six herbicides (amidosulfuron, chlorsulfuron, imazamox, propoxycarbazone, pyroxsulam, sulfosulfuron) were applied at three application rates (1N - full, 0.5N - half, and 0.05N - 5 % of full). One and four months after application, half of each plot was sown with oilseed rape, and the other half was sown with sugar beet. Herbicide phytotoxicity and aboveground biomass were assessed four weeks after crop emergence. Weather conditions during experimental years, herbicides used, herbicide application rates and the period between herbicide application and crop sowing affected herbicide phytotoxicity and aboveground biomass of both crops. The most damaging effects were recorded with the application of chlorsulfuron for oilseed rape (phytotoxicity was 96–98 % at one month after 1N application) and sulfosulfuron and chlorsulfuron for sugar beet (phytotoxicity was 97–100 % and 90–100 %, respectively). Pyroxsulam caused the least damage to both the crops (average phytotoxicity was 18 %). Herbicide phytotoxicity was 3-times higher, and crop biomass was almost half as much as at the first assessment compared to the second assessment. Sugar beet was more sensitive than oilseed rape to chlorsulfuron and sulfosulfuron, especially in dry conditions, where 0.05 N rates caused biomass reduction of 20–60 % in sugar beet.

A survey of broomrapes infestation was conducted to clearly establish the extent of their status in Xinjiang. Results indicated that broomrapes occurred in 34 % of sampling sites with varying degrees of infection.

We conducted five field experiments in two cropping seasons, where we tested pyrethroid insecticide application in autumn targeting <em>C. sulcicollis</em>, in spring targeting <em>C. pallidactylus</em>, as well as combined applications in autumn and spring targeting both species. We evaluated stem injury, emergence of the new generation of weevils and crop yield and oil content. Insecticide treatment in autumn reduced stem injury length and severity by <em>C. sulcicollis</em>, whereas insecticide treatment in spring did not affect stem injury. Emergence of the two species was similar across all treatments, which possibly was an artefact of limited sampling effort and small-scale spatial heterogeneity in emergence. Insecticide treatment in autumn, spring or a combined treatment all increased yield by 8–10 % (185–245 kg ha⁻¹) with minor effects on oil content. Our results show that <em>C. sulcicollis</em> cause significant yield loss that can be reduced by insecticide treatment in autumn, which therefore can be economically motivated, whereas the results for insecticide treatment in spring targeting <em>C. pallidactylus</em> are inconclusive.
