BioCover MLT is an oil spray that kills insects by interfering with their respiration and metabolism and can disrupt feeding and virus spread. Ground application only. Make dilute applications for thorough coverage and to reduce the potential for phytotoxicity. Apply once per week, or twice per week if the crop is growing rapidly and pest pressure is high. Avoid spraying during or immediately prior to hot weather (over 95 degrees F). Phytotoxicity is more likely when plants are stressed. Similar mineral oil sprays are available, but use rates vary depending on the product.

| Aphid (various species) | NC | F-P | See Label | 4 h | Apply when aphids first appear to limit spread of Potato Virus Y, or before aphids are present in large numbers if the goal is to keep aphid numbers in check and virus spread is not a concern. | |
| Potato Psyllid (Bactericera cockerelli) | NC | ND | See Label | 4 h | Apply before psyllids colonize the field (i.e., before nymphs develop into second generation adults) to limit spread of zebra chip disease. | |

2 Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
3 Rate per acre per application. Refer to the product label for maximum use rate per season.
4 Reentry interval.
5The minimum pre-harvest interval. Some products do not list PHI.
Note: always read and follow the directions on the pesticide label.
