Abstract: Compounds having the formula (I) below:(R.sub.1 R.sub.2 N)CH.sub.2 --CH.dbd.CH--CH.sub.2 (NR.sub.3 R.sub.4)(I)wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different represent hydrogen atoms, an alkyl group having from 1 to 6 carbon atoms, a cycloalkyl group of 3 to 6 carbon atoms, a heterocyclic group, an aryl group, a heteroaryl group having from 3 to 6 atoms, an amidino group or R.sub.1, R.sub.2 and/or R.sub.3 and R.sub.4 together represent a carbocyclic or heterocyclic group comprising from 3 to 6 atoms with the proviso that R.sub.1, R.sub.2, R.sub.3 and R.sub.4 cannot simultaneously represent hydrogen and salts thereof are fungicides especially mildewicides. Preferred compounds are those wherein the groups R represent methyl or ethyl groups.

Abstract: Use of a compound having the general formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 which may be the same or different represent hydrogen atoms or alkyl groups of 1-6 carbon atoms, or NR.sup.1 R.sup.2 and/or NR.sup.3 R.sup.4 together represent a heterocyclic group having 5 or 6 ring atoms, x is 0 or 1 and when x is 0, the dashed line represents a double bond, W represents a saturated or ethylenically unsaturated divalent hydrocarbyl group required to complete a cycloalkane, cycloalkene or cycloalkadiene ring of 3 to 6 ring atoms and from 0 to 2 double bonds, in the form of the free base or an acid addition salt tolerable to plants, as a plant fungicide, as a fungicide, especially as a mildewicide.Some of the compounds of formula (1) are new and are claimed per se.

Abstract: The use of (E)-2-butene-1,4-diamine or a salt thereof with inorganic or organic acids, as a fungicide.

Abstract: An ender and bunching type choker hook are disclosed for use with a hauling cable to releasably interconnect a plurality of choker cables therewith. The choker hook provides an eye for slidable engagement on a hauling cable and an interconnecting, angularly oriented body defining a spatially skewed, key type slot for releasably fastening the ferruled end of a choker cable, upon particular manipulation for placement or release. The ender comprises a choker hook eye and body with a fastening structure carried in the eye to define an orifice that allows sliding motion of a hauling cable therethrough but does not allow passage of a ferrule end of that cable.
