The effectiveness of selected insecticides against capsule weevils (Neoglocianus maculaalba) and capsule midges (Dasineura papaveris), which are the main pests of breadseed poppy, was verified in a small-plot field experiment in 2015–2017. The effect of foliar application was evaluated according to boreholes on capsule surfaces caused by the feeding of capsule weevil adults and larvae numbers in capsules collected approximately 4 weeks after application. Biological efficacy of the tested biological formulations Spintor (active ingredient spinosad 240 g/l) in dosage 0.4 l/ha and NeemAzal T/S (active ingredient azadirachtin A 10.6 g/l) in dosage 3 l/ha against N. maculaalba larvae in individual years of monitoring ranged from 46.4% to 77.7% and from 67.7% to 82.9%, respectively. The effect of the formulation Prev B2 (boron ethanolamine corresponding to 2.1% of water-soluble boron) in 0.3% dosage was in the range of 59.5–81.9%. Their efficacy did not differ significantly compared to the registered chemical standards Biscaya 240 OD (active ingredient thiacloprid 240 g/l) and Decis Mega (active ingredient deltamethrin 50 g/l). Therefore, these biological insecticides are potentially useful for the effective control of N. maculaalba and D. papaveris population densities and reduction of damage they cause to breadseed poppy.

Poppy seed (Papaver somniferum L.) is an annual autumn or spring plant. This crop is cultivated generally for seed which is used as a foodstuff in food processing industry. The biological efficacy of different tested active ingredients (lambda-cyhalothrin, bifenthrin, aplha-cypermethrin, DE-225 and combination chlorpyrifos + cypermethrin) on poppy weevil (Stenocarus ruficornis S.) was evaluated in comparison with reference active ingredient (carbofuran) used as a standard treatment. The active ingredients were applied against the mentioned pest once in the season and were used in doses which were similar to those used against stem weevils in winter oil seed rape. Reference active ingredient was used in the dose which was authorised in the Czech Republic as standard ones against the poppy weevil. All active ingredients revealed efficacy which was measured (as a size of injuries) both on leaves and roots. Two trials were performed in 2001–2002 in which efficacy and selectivity were assessed.

SUMMARYAbnormally low concentrations of morphine in capsules of poppy (Papaver somniferum L.) in the 1970–1 season were associated with heavy fungal colonization. The effect of fungal colonization on the morphine production of capsules was later studied in a series of field, glasshouse and in vitroexperiments.In a field experiment morphine concentration of severely colonized (> 30% surface cover) intact capsules was 20% less (P <0·01) than slightly colonized (< 10% surface cover) capsules. Colonization of these field-grown capsules was generally localized in the top half and the morphine concentration of the top half was about 20% less than the bottom half for all colonization categories. In contrast, glasshouse-grown capsules were free of fungal colonization and the top and bottom halves had similar morphine concentrations.In a field experiment studying the effect of fungicides, 2 kg benomyl (50% a.i.) + 2 kg mancozeb (80% a.i.)/ha were applied as a spray at 10-day intervals from flowering till 1 month after commercial harvest and plants were harvested at weekly intervals from 10 days after full bloom. The mean dry-matter yield of sprayed capsules was 11% greater (P <0·01) than non-sprayed with a similar trend for morphine concentration and morphine yield. In addition, the sprayed treatment significantly reduced the area covered by sporulating lesions on the surface of the capsule after dry maturity. This superficial fungal cover had a NNE orientation in both sprayed and non-sprayed capsules.In an in vitroexperiment using capsules from the field fungicide study, fungi were isolated from the interior of green capsule wall tissue as early as 17 days after flowering. Colonization increased with successive harvests and culturing of fungi from the interior of capsule wall tissue showed the presence of fungi in both sprayed and non-sprayed capsules with no difference in the degree of colonization.Two of the major fungi isolated from the field experiment were identified as Dendryphion penidllatum (Corda) Fr. and Alternaria alternata (Fr.) Keissler and the individual effect of these was assessed in an in vitro experiment using ground capsule material. D. penidllatuvi and A. alternata reduced the morphine concentration of ground capsules in 24 days to 7 and 11% respectively of non-inoculated controls.

Abstract. The North China plain (NCP) including Beijing is currently suffering from severe haze events due to high pollution level of atmospheric fine particles called PM2.5. To mitigate the serious pollution status, identification of the sources of PM2.5 is urgently needed for the effective control measures. A total of 235 daily samples of PM2.5 were collected in Beijing through the year of 2014, and the variation characteristics of water-soluble ions (WSIs) in the PM2.5 were comprehensively analyzed for recognizing their possible sources. The results indicated that the periodic emissions from farmers' activities made evident contribution to the atmospheric WSIs in Beijing. The unusually high ratio of Cl− to Na+ in summer could be rationally explained by the prevailing fertilization of NH4Cl for planting summer maize in the vast area of NCP. The remarkable elevation of Cl− in winter was ascribed to coal combustion for heating by farmers. The most serious pollution episodes in autumn were coincident with significant elevation of Ca2+ which was ascribed to be from harvest of the summer maize and tillage for planting the winter wheat. The mineral dust emission from the harvest and tillage not only increased the atmospheric concentrations of the primary pollutants, but also greatly accelerated formation of sulfate and nitrate through heterogeneous reactions of NO2 and SO2 on the mineral dust. The relatively high concentration of K+ in winter and autumn further confirmed that crop straw burning made evident contribution to atmospheric PM2.5 in Beijing. The backward trajectories also indicated that the highest concentrations of WSIs usually occurred in the air parcel from southwest/south regions with high density of farmers. In addition, the values of nitrogen oxidation ratio (NOR) and the sulfur oxidation ratio (SOR) were found to be much higher under haze days than under non-haze days, implying that formation of sulfate and nitrate was greatly accelerated through heterogeneous or multiphase reactions of NO2 and SO2 on PM2.5.

Indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid, and maleic hydrazide were applied as foliar sprays to 10-week-old sugarcane plants during initial studies of the interrelationships of growth-regulating materials with the sugar-metabolizing enzymes of sugarcane. Leaf samples were harvested at 1, 3, 9, and 27 days following treatment for sugar and enzyme assays. Sugar analyses were run for total ketoses, sucrose, fructose, and total reducing sugars, with glucose being determined by calculation. A series of acid phosphatase assays were conducted using as substrates the following compounds: ß-glycerophosphate, adenosinetriphosphate, uridine diphosphate glucose, glucose-1-phosphate, glucose-6-phosphate, fructose-6- phosphate, fructose-1,6-diphosphate, and 3-phosphoglyceric acid. Additional enzymes included invertase, amylase, hexokinase, phosphohexose isomerase, aldolase, triosephosphate dehydrogenase, phosphoglyceryl kinase, condensing enzyme, isocitric acid dehydrogenase, transaminase, peroxidase, and glucose oxidase. All enzyme preparations consisted of dialyzed water-soluble protein extracted from freeze-dried leaf tissue and precipitated with ammonium sulfate between 35 and 95 percent of saturation.

The field experiment was undertaken at the District Seed Farm, Kalyani at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during summer season of 2012 and 2013 to study the growth and yield of summer groundnut as influenced by application of water soluble foliar grade fertilizer. Application of liquid grade fertilizerat early growth stage up to 45 DAE did not influence the plant height and dry matter production significantly, but towards maturity varied significantly (P ≤ 0.05). Crop growth rate was faster at early part of the crop age and gradually slows at later part towards maturity. Foliar application of water soluble fertilizer along with RDF 85% had the significant (P ≤ 0.05) influence to increase the number of pods per plant, but shelling percentage and hundred kernel weight did not vary significantly. Liquid grade fertilizer either starter dose or booster dose or in both had the positive response to increased the groundnut pod yield up to 4-6 % over RDF only. The crop was equally responsive in increasing the pod yield, when RDF was reduced by 15% along with foliar application of liquid grade fertilizer. The foliar application of water soluble fertilizer was not the substitute to soil applied inorganic fertilizer. Instead, foliar supplementation of nutrients showed positive response to increase the pod yield, in addition to the fertilizers added to soil. Gross return decreased with reduction in amount of RDF applied for the crop, but gross return increased, when water soluble foliar grade inorganic fertilizer was supplemented with RDF. The maximum gross return of `150399 was obtained. The results obtained from correlation analysis carried out to examine the linear relationship between pod yields with different plant characters. Data obtained in case of dry matter of the plant was 0.995 and 0.997 in the respective years at 1% level of significance. Thus, it was concluded that dry matter content of plant is solely responsible over the yield increase in groundnut and foliar application of inorganic fertilizers in addition to that in soil has helped in better adsorption of nutrients in adequate amount by the crop.

Field investigation was carried out to study the influence of quality parameters and nutrient uptake of brinjal hybrids due to application of various levels of water soluble fertilizer. Foliar spray of NPK (19:19:19) at 0.5 per cent and 1% along with 100 and 75% recommended dose of NPK (200:150:100 kg ha-1) with 5 and 7 sprays, each starting from 30 DAT at 10 d interval, formed twenty treatments in two hybrids. Results showed that among the two different concentrations of foliar applied nutrients, 7 sprays of 1% NPK (19:19:19) along with 100 per cent recommended dose of fertilizer (200:150:100 kg ha-1) recorded the ascorbic acid content, total soluble solids (TSS) and total phenol content. Uptake of major nutrients was found to be the highest due to foliar application of 1 per cent water soluble fertilizer (7 sprays) along with 100 per cent recommended dose of fertilizer.

The article presents data on the study of the effect of foliar water-soluble mineral fertilizer NOVATEK Solub K-Max 10-5-30 on the biochemical composition and commercial quality of apple fruits. A rise in vitamin C from the introduction of NOVATEK at a rate of 2.5 kg/ha indicates the effectiveness of this drug for optimizing the content of ascorbic acid in fruits. An increase in the content of monosaccharides and a decrease in disaccharides were found for all the studied rates of consumption of agrochemicals. The use of mineral fertilizer “Novatek Solub K-Max” contributed to increase the dry weight of fruits. The application of this mineral fertilizer is recommended for inclusion in the industry regulations for Apple cultivation as one of the elements of the technology.
