On the '9', make sure that the tail of the 9 crosses underneath the rope, unlike on the '6'.

On the first picture, see how the two ropes form a '69' or a 'b' and a 'q'. It also turns out to be very easy to learn with the so-called '69' or 'b & q' method. That it is-it comes loose much more easily than the double sheet bend, let alone the Alpine butterfly bend or the double fisherman's knot. The bend is known to be extremely reliable (you can entrust your airship to one of them!) and easy to untie. I just had to learn the Zeppelin bend in honor of these majestic airships from another era.

Apparently, Charles Rosendahl, an American skipper of rigid airships (who happened to be traveling on the Hindenburg on the day it burned) insisted that the Zeppelins only be moored using what is now known as the Zeppelin bend. The beauty of the black-and-white footage blew me away. 'dirigibles' or 'Zeppelins', as they are commonly known in honor of Count Ferdinand von Zeppelin, who pioneered the design of these ships, and of his company (the Luftschiffbau Zeppelin GmbH), which manufactured its most famous models. The doco retraced the history of rigid airships, a.k.a. This all changed when I watched a documentary about the Hindenburg, an 803-foot long lighter-than-air airship that burst into flames in 1937. For a long time I resisted learning it because I thought I knew enough bends, such as the double sheet bend on this site's main knot page. javanica Meloidogyne arenaria Pennisetum glaucum Vigna unguiculata cover crops cowpea jack bean management mustard pearl millet root-knot nematodes sorghum-sudangrass sunflower.This method of tying two ropes together ('bend') appears in most recent knot books (but not in Ashley) under the names of 'Zeppelin' or 'Rosendahl' bend. The remainder of crops tested had significant levels of galling, J2, and eggs associated with roots, which varied among the Meloidogyne species tested.ĪSD Anaerobic soil disinfestation Brassica juncea & Sinapis alba Canavalia ensiformis Eruca sativa Helianthus annuus M. Arugula, cowpea, and sorghum-sudangrass consistently had low numbers of all three Meloidogyne species associated with roots and are good selections for use in ASD for root-knot nematode control. Sunflower, jack bean, and both mustard mixtures exhibited significant galling in response to M. javanica, and all sunflower cultivars had high numbers of eggs isolated from roots. Jack bean and all three cultivars of sunflower were highly susceptible to M.

Arugula, cowpea, and mustard mixture Caliente 99 did not support M. incognita J2 were isolated from the soil. incognita in roots or exhibit significant galling, although high numbers of M. Several cover crops did not support high populations of M. arenaria J2 isolated from roots than the other sunflower cultivars, less galling than tomato, and fewer eggs than tomato and sunflower cv. arenaria, with the exception of jack bean. The majority of cover crops tested were less susceptible than tomato to M. Rutgers) was included in all trials as a susceptible host to all three nematode species. Sugar Grazer II), and three cultivars of sunflower (Helianthus annuus, cvs. Tifleaf III), sorghum-sudangrass hybrid (Sorghum bicolor × S.

Comum), two commercial mixtures of Indian mustard and white mustard (Brassica juncea & Sinapis alba, mixtures Caliente 61 and Caliente 99), pearl millet (Pennisetum glaucum, cv. Iron & Clay), jack bean (Canavalia ensiformis, cv. Nematode juvenile (J2) numbers in soil and roots, egg production, and host plant root galling were evaluated on arugula (Eruca sativa, cv. Crops were selected based on potential use as organic amendments in anaerobic soil disinfestation (ASD) applications. Several cover crops with potential for use in tropical and subtropical regions were assessed for susceptibility to three common species of root-knot nematode, Meloidogyne arenaria, M.
