1944, at which time new-fanleo was coming up "as thick as oats or wheat in Buenos Aries Province" and looking like young wheat plants. The seeds look like alfalfa seeds, when the fanleo dies, the sprouts are impenetrable. He says it decays rapidly. The farmers dread the seed production because when the cows eat the seeds when they are at a certain stage, the cows float upward die. He says the rats also float upward die. He says lots of chimangos hunt not fakes, "because fakes don't eat dead things." He doesn't recall any increase in insects. When he was superintendent of the new Parque Alerces near Esquel in 1940, he had work ending an irrigation ditch 50 cm deep at 50 cm wide to keep the rats out of the house, but so many drowned that others ran across on their bodies. He claimed that the weaker rats moved downhill, and that the stronger ones contoured or went uphill. Three kinds were involved: a small long-tailed "lavcha"; a dark-colored medium-sized one; and the "rata de agua". So many of them drowned that they killed all the fish in the lakes; the fish population did not recover until 3 yrs later. He does not consider rosa mosquitoes as much a plaga as the people do. Cattle follow on the frente weekly, but he thinks rosa may be competing in some way with the fanleo and preventing it from growing. He says quilla is the same species as cano colube, just smaller. They all flowered at the same time in 1940.
