On a TreegatorÂ® Original, the water release holes are located on the bottom corners on the front of the bag, just behind the folds. On a TreegatorÂ® Jr. Pro, the emitter valves are located on the underside of the bag. Just turn over an empty TreegatorÂ® Jr. Pro (red fill valve face down) to find them.
Chemical Class: benzimidazole. Introduction: Benomyl is a systemic, benzimidazole fungicide that is selectively toxic to microorganisms and to invertebrates, especially earthworms. It is used against a wide range of fungal diseases of field crops, fruits, nuts, ornamentals, mushrooms, and turf.
Crayfish are much more resistant with a benomyl induced LC50 greater than 100 mg/l. The estimated bioconcentration factor (BCF) ranges from 159 in rainbow trout up to 460 in bluegill sunfish indicating that benomyl does not tend to significantly concentrate in living tissue (2, 8).he compound is very lethal to earthworms at low concentrations over a long time period. The seven-day LC50 was 1.7 mg/l and the 14-day LC50 is 0.4 mg/l (3). Benomyl also decreases the mixing of soil and thatch. The effects lasted for up to twenty weeks (9). The compound is relatively non-toxic to bees (7).
