Different rates of granular formulations ofaldicarb, carbofuran, ethoprop, fensulfothion, and phenamiphos were applied directly onto garlic seed cloves in the seed furrow in sandy clay loam, clay loam, and loam soils at planting to assess efficacy for control of Ditylenchus dipsaci in infected seed cloves. All treatments were compared to hotwater-formalin clove dip disinfection treatment and to...

Calorie values for a wide biological selection of nematodes, determined with a microbomb calorimeter, ranged from 3.86 to 6.85 Kcal/g. The mean of 5.095 Kcal from 16 species was lower than means recorded in three previous studies of other invertebrate groups. The nematode values were skewed to the lowest limit. Larvae of Ditylenchus dipsaci showed lower calorie values after storage, and the cal...

The effects of abamectin B1, diazinon, and methiocarb insecticides on Aphelenchoides fragariae and Ditylenchus dipsaci in Lamium maculatum, Phlox subulata, Rhododendron indicum, and Begonia x tuberhybrida were determined in a series of greenhouse experiments. Abamectin at 0.005 or 0.011 g a.i./liter (0.3 or 0.6 ml/liter Avid 0.15 EC), diazinon at 0.62 or 1.87 g a.i./liter (2.6 or 7.8 ml/liter K...

The stem and bulb nematode, Ditylenchus dipsaci, is a plant parasite that causes significant economic losses to growers of the main host plant, onion. Fungal mycorrhizae can increase growth induce systemic resistance against many diseases pests. However, no evidence detailed study was found regarding relationship with D. dipsaci. In this study, effects fungus, Rhizophagus irregularis, on onion ...

Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis synergistically affected the mortality and plant growth of Ranger alfalfa, a cultivar susceptible to stem nematode and Fusarium wilt. The nematode-fungus relationship had an additive effect on mortality and plant growth of Lahontan (nematode resistant and Fusarium wilt susceptible) and of Moapa 69 (nematode susceptible and Fusarium w...

Stem and bulb nematode, Ditylenchus dipsaci Kühn, 1857 (Tylenchida: Anguinidae), is one of the most important plant parasitic nematodes worldwide. The host range local populations needs to be determined for control using crop rotation. Susceptibility 29 species was tested onion garlic D. from Central Anatolian Plateau in Turkey under growth chamber conditions Karaman 2019. Based on reproduction...

Abstract The stem nematode, Ditylenchus dipsaci , is a severe pest in European sugar beet production. In France, Germany, and Switzerland, D. damage varies among specific geographic areas. this study, the reproduction potential of four geographically distinct populations was determined using sterile carrot disc cultures. addition, virulence pathogenicity were investigated in-vivo beet. No diffe...
