Abstract: The effect of weed control (interrow cultivation with and without hoeing ­- untreated control and seven herbicide mixtures) in tobacco fields was evaluated on three types of soil in Croatia during 2001-2003. The total weed biomass was significantly higher (P<0.01) in all localities in 2002 that was more humid than the extremely dry 2003. In untreated control the dominant species in the total weed biomass were the annual grass weed Echinochloa crus-galli (L.) PB. with 75% on sandy loam (SL), 25% on pseudogleyic (P), and the smallest share of 9% on eutric cambisol (EC). Dominant annual broad-leaved weeds were Amaranthus retroflexus L., Chenopodium album L., Portulaca oleracea, Polygonum lapathifolium L. on (SL), and on (EC) among the most abundant weed populations were Ambrosia artemisiifolia L., Abutilon theophrasti Med. and perennial species Sorghum halepense (L.) Pers. and Convolvulus arvensisL. Herbicide variants 1, 2, 3, 4, 6, and 7 reduced well (84-99.6%) the biomass of the annual grass weeds Echinochloa crus-galli (L.) PB. and Setaria glauca (L.) PB. The efficacy of herbicide mixtures in reducing the biomass of annual broad-leaved weeds varied more significantly in different localites and years of investigation (58-98.7%). Regarding the total efficacy in reducing the total weed biomass, the herbicide variants were ranked as follows: 1, 7, 3, 2, 4, 6 and 5.

Abstract:According to an investigation of floristic composition and the structure of weed community of the apple plantation in the region of Sarajevo, it was found the total of 28 weed species. The characteristic group of the community was made of total of 7 species. Studies of vegetation dynamics of weed sinuosity in apple orchards with intensive production in the Sarajevo region have demonstrated that the production area in these orchards can be divided into two microdomiciles, such as: a microdomicile in the rows (under the fruit tress), and a microdomicile between the rows of fruit tress. The microdomiciles were established trough studies of agrophytocoenoses and anthropomeras. They have been represented with high abundance and cover degree, therefore creating the main mass of weeds in the plantation. Weed community had a therophytic character with significant presence of hemicryptophytes and slightly lower representation of geophytes. Weed–ruderal species were more represented than the weed species, while the contribution of meadow and ruderal species was the lowest. Weed community of apple orchard was analyzed as two separate parts: row and spacing area. Significant differences between those two producing spaces were established, especially in the floristic composition both in qualitative and the quantitative sense. The highest similarity in floristic composition was detected between whole weed community and the part of weed community developed in rows. The lowest floristic similarity was found between weed community in the row zone and the spacing area.

Abstract: The objectives of this study were to investigate the influence of an ecological and integrated farming system on development of actual weed infestation. In our experiment were analyzed crop conditions and weed infestation of crops and their dependence of different manuring and fertilizing methods. Field experiments were established at the Slovak Agricultural University Research Station Dolná Malanta on brown clay-loamy soil in 1992. The actual weed infestation was evaluated during eight years, from 1998 till 2005, by standard methods common used by EWRS: a) numerous method; b) numerous-weight method. In integrated system as a weed regulation techniques were used chemical treatments and cultural methods, while in ecological only cultural and mechanical ones. According to the achieved results it is evident, that the farming system showed higher influence on development of actual weed infestation and weed species diversity, which points higher weed infestation and species diversity in ecological than in integrated system. In integrated agricultural system and cereal crops dominant weed species were (according to the level of infestation): Cirsium arvense, Stellaria media, Medicago sativa, Cardaria draba, Tripleurospermum perforatum, Chenopodium album, Convolvulus arvensis, Thlaspi arvense, Capsella bursa pastoris, Lamium purpureum, Avena fatua, Persicaria maculosa, Amaranthus retroflexus. In ecological system dominant weed species were: Tripleurospermum perforatum, Chenopodium album, Cardaria draba, Capsella bursa pastoris, Cirsium arvense, Lamium amplexicaule, Lamium purpureum, Thlaspi arvense, Stellaria media, Galium aparine, Polygonum aviculare. Contamination of live environment in integrated agricultural system and herbicide costs lead as to idea to grow agricultural crops by using only cultural, preventive and mechanical weed regulation methods, the same as in ecological system. This claim is feasibly only in cereal crops.

Rezumat: Atacul principalilor dãunãtori de depozit, intensitatea atacului, numãrul de generaþii, etc. depind de condiþiile de temperaturã ºi umiditate precum ºi tratamentele fãcute în depozit. Fiecare tip de magazie sau depozit asigurã mai bine sau mai puþin bine condiþiile optime pentru pãstrare. S-a obesrvat cã silozurile moderne sunt singurele care pot da rezultate foarte bune în ceea ce priveºte  pãstrarea corespunzãtoare a seminþelor. Controlul depozitelor trebuie efectuat sistematic. În lucrare sunt prezentate date cu privire la infestarea cu specii dãunãtoare depistate în13 depozite din jud.Timiº. În urma analizelor de laborator au fost  identificaþi urmãtorii dãunãtori: Tribolium confusum, Sitophilus granarius, Sitotroga cerealella ºi Mus musculus, cu o evaluare a atacului de la slab la puternic atacat.

Abstract:Biological specialization of Blumeria graminis fungus is concretized through 11 “special forms” and more than 70 physiologic races, intraspecific units generated by a trophic base formed from 9838 angiosperm species that are owned by 1617 plant genera. The most spread physiological races are those that attack Pm1 and Pm8 resistance genes. Alex, Arieºan, Boema, Crina, Ciprian, Delabrad, Farmec, G.K. Othalom, Izvor, Partizanka, Lovrin 34, Bezostaia, Flamura 85, Turda 95, and Turda 2000 wheat varieties are sensitive to those races; for production varieties, if those genes lose their vertical action can determinate an partial resistance. Physiological races with complementary structure for Pm2, Pm3, and Pm5 genes have an average frequency an are attributed to Ardeal, Renan, Fundulea 4, Dropia and Holda wheat varieties, determining a medium resistance, which can be provided by minor genes with medium activity. Bercsy, Dor, Falnic, Gloria and Gruia wheat varieties proved to be resistant because of vertical action of Pm2b and Pm4 genes or because of the new Pm1a and Pm8a oligogenes, and possible because of the action of a minor gene. Biological specialization through intraspecific structures appeared into Blumeria graminis f.sp. tritici species (as f.sp. and physiologic race) results from the great genetic plasticity of the fungus, and creates great difficulties to the plant breeders during the realization of a genetic control of powdery mildew as therapy through resistance genes; in this way we recommend cultivation of resistant varieties mentioned before.

Abstract: We present the results of the research made on the implication of no-tillage culture system and crops rotation over the O.N. Hb attack on corn from Vinga Field. It has resulted that because of the lack of soil till and the maintenance of the vegetal residues on the soil, there appear elements that favour the transition from one year to another and the growth of the insects if the environmental factors are favourable to the population. The frequency of the attack has had a tendency to rise in the no-tillage monoculture system, but as far as the annual dynamics is concerned, only in the third year of no-tillage system implementation has there been achieved a superior level of growth (51,67%), unlike the average (40,0%). The insect attack was appreciated within the limits of average values: 17,33-33,44% frequency of attack, 4,83-5,18% intensity of attack, and 0,93-1,66% degree of attack. The crop rotation contributed to a significant decrease of the frequency of attack.
