One US dollar = 16 L.E. There are broad host range claims by the manufacturer’s product labels which have not necessarily been confirmed in independent trials
^aFigures given for comparative purposes when products are uniformly applied to the soil (except oxamyl for foliar application too). For some products and other, including low-value, crops, product may be incorporated into field soil, potting mix, or applied in greenhouses for which different rates apply
