The effectiveness of dimethyl disulfide (DMDS) to control root-knot nematodes (Meloidogyne spp.) and weeds was tested for the first time in Hungary in two consecutive protected cucumber crops with application made only before the first crop. The treatments were Accolade EC (DMDS 94.1%) at 400 l/ha applied by driplines, Nemathorin 10 G (fosthiazate) at 30 kg/ha, and an untreated control. During the first cucumber cycle vigour-index, yield, root-gall index, Meloidogyne juveniles in the soil and germination of weeds were evaluated. All considered parameters were significantly improved by using DMDS compared respectively to the chemical standard and untreated control: (i) vigour-index of 7.0, 4.3 and 3.6; (ii) cumulative yield/sample of 45.1 kg, 30.9 kg, and 16.6 kg; root-gall index (RGI) of 1.2, 4.9, and 5.9; (iii) M. incognita J2/25 g soil of 0.25, 48.5 and 78.0, and (iv) number of weed seedlings/sample in the 20–30 cm soil profile of 1.1, 2.6, and 4.2. During the second cucumber crop, only root-gall index was evaluated. Results showed that a single DMDS treatment applied before the first crop had a prolonged beneficial effect on the following crop. In the second crop cycle, root gall indices were 5.58, 9.18, and 8.44 for DMDS treated plots, chemical control and untreated control, respectively.
Suppose that K and K' are knots inside the homology spheres Y and Y', respectively. Let X = Y (K, K') be the 3-manifold obtained by splicing the complements of K and K' and Z be the three-manifold obtained by 0 surgery on K. When Y' is an L-space, we use the splicing formula of  to show that the rank of (X ) is bounded below by the rank of (Y ) if τ(K 2) = 0 and is bounded below by rank((Z)) − 2 rank((Y)) + 1 if τ(K') ≠ 0.

Horizontal (field) resistance to late blight and common scab that is controlled by numerous genes proved to be quite durable in certain potato varieties in Hungarian trials. Although it is difficult to breed for this type of resistance, it has become the preferable strategy in today's breeding programmes, providing long-lasting and less vulnerable protection. Potato breeding in Hungary has produced some promising cultivars such as White Lady, Százszorszép and Rebeka with multiple disease resistance that may play an important role in the Integrated Pest Management (IPM) of near future.
Species richness and composition of carabid assemblages were investigated on the ground surface of differently treated (abandoned, commercial and IPM) apple and pear orchards in Hungary. Extensive sampling was carried out by pitfall trapping in 13 apple and 3 pear orchards located in ten different regions. 28 230 individuals belonging to 174 species were collected. Additional four species were collected by trunk-traps and 23 species were found during the review of earlier literature. Altogether 201 carabid species representing 40% of the carabid fauna of Hungary were found in our and earlier studies. The species richness varied between 23 and 76 in the different orchards, the average species richness was 43 species. The common species, occurring with high relative abundance in the individual orchards in decreasing order were: Pseudoophonus rufipes, Harpalus distinguendus, Harpalus tardus, Anisodactylus binotatus, Calathus fuscipes, Calathus erratus, Amara aenea, Harpalus affinis and Pterostichus melanarius. The species with wide distribution, occurring in more than 75% of the investigated orchards in decreasing order were: Pseudoophonus rufipes, Trechus quadristriatus, Harpalus tardus, Harpalus distinguendus, Pterostichus melanarius, Amara aenea, Amara familiaris Calathus fuscipes, Poecilus cupreus, Calathus ambiguus, Calathus melanocephalus, Pseudoophonus griseus and Harpalus serripes. Species, which are rare in Hungary, and therefore are interesting in respect of faunal research, were: Amara cursitans, Harpalus progrediens, Notiophilus pusillus, Olisthopus rotundatus, Pangus scaritides and Parophonus hirsutulus.
