One of the most important treatments of the year is for cochylis, otherwise known as the totrix moth, or rather more fondly, the "cuc del raim" - the grape worm. The larva of this moth can cause havoc in the vineyards, and the farmers spray against it on a strict schedule. The local oenologists monitor the cycle of the moth, and decide on the most appropriate days to spray against it. In Aiguamúrcia, they decided to start on the lower altitude vineyards on July 2nd, progressing to the higher areas on the 4th and 5th.

Although the products used nowadays are progressively less toxic, (and spraying on the correct days requires a less aggressive treatment) a protective mask is in order to avoid inhaling the pesticide, particularly when using the ventilator fan on the back of the tank.
