AGRICULTURAL USE REQUIREMENTS

Use this product only in accordance with its labeling and with the Worker Protection 

Standard, 40 CFR Part 170. This Standard contains requirements for the protection of 

agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of 

agricultural pesticides. It contains requirements for training, decontamination, 

notification, and emergency assistance. It also contains specific instructions and 

exceptions pertaining to the statements on this label about personal protective equipment 

(PPE), and restricted entry intervals. The requirements in this box only apply to uses of 

this product that are covered by the Worker Protection Standard. 

Do not apply this product in a way that will contact workers or other persons, either 

directly or through drift. Only protected handlers may be in the area during application. 

Do not enter or allow worker entry into treated areas during the restricted entry interval 

(REI) of 12 hours. 

PPE required for early entry to treated areas that is permitted under the worker Protection 

Standard and that involves contact with anything that has been treated, such as plants, 

soil, or water is: 

 Coveralls 

 Chemical resistant gloves, such as barrier laminate or nitrile rubber or neoprene 

rubber or viton 

 Shoes plus socks

NON-AGRICULTURAL USE REQUIREMENTS

The requirements in this box apply to uses of this product that are NOT within the scope 

of the Worker Protection Standard for agricultural pesticides (40 CFR Part 170). The 

WPS applies when this product is used to produce agricultural plants on farms, forests, 

nurseries, or greenhouses. 

Do not enter treated areas without protective clothing until sprays have dried.

MODE OF ACTION

Insecticide: After eating a lethal dose of LEAP®,Biologibal Insecticide, larvae stop feeding 

within the hour, and will die within several days. Dying larvae move slowly, discolor, then 

shrivel, blacken and die. 

Bacteriacide: LEAP® contains methyl salicylate, a known inducer of host plant resistance. Use 

of methyl salicylate in a preventative manner can trigger a defense response independent of 
LEAP/Leap

infection, enhancing the plant’s ability to fight infection, thus preventing, or suppressing 

pathogen damage. 

LEAP may be used in either the field or greenhouse for the control of any labeled pest. 

GENERAL INSTRUCTIONS

LEAP is a highly selective insecticide for use against listed caterpillars (larvae) of Lepidopterous 

insects. Close scouting and early attention to infestations is highly recommended. Larvae must 

eat deposits of LEAP to be affected. Use of LEAP will also induce a systemic response in 

treated plants, enhancing the ability of the plant to resist disease infection and spread. Always 

follow these directions: 

 Treat when larvae are young (early instars) and before economic thresholds of damage have 

been exceeded. 

 Larvae must be actively feeding on treated, exposed plant parts. 

 Thorough spray coverage is needed to provide a uniform deposit of LEAP where larvae feed 

and for maximal disease control. For some crops directed drop nozzles by ground machine 

are required. As crop matures and the canopy increases in size, increase water volume to 

ensure complete foliage coverage. 

 Under heavy pest population pressure, use the higher label rates, shorten the spray interval, 

and/or increase spray volume to improve coverage. 

 Repeat applications at an interval sufficient to maintain control, usually 5 to 14 days 

depending on plant growth rate, moth activity, rainfall after treating, and other factors. If 

attempting to control a pest with a single application, make the treatment when egg hatch is 

essentially complete, but before economic crop damage occurs. 

 For bacterial pathogen suppression, LEAP must be used before the disease is observed in the 

field. For best results, use as part of a plant pathogen control program in rotation or tank 

mixed with other commercial bactericides and fungicides in a preventative manner. If disease 

is already present in the field, LEAP should be tank mixed with other registered funigicides 

or bactericides to ensure adequate control. 

 LEAP is a non-restricted use pesticide and does not require a restricted use permit for 

purchase or use. 

 LEAP may be tank mixed with other labeled insecticides and fungicides to enhance control. 

Use of the resulting tank mix must be in accordance with the more restrictive label 

limitations and precautions. No dosage rates should be exceeded. This product cannot be 
LEAP/Leap 

Page 6 of 9

mixed with any product containing a label prohibition against such mixing. Before tank 

mixing LEAP with other labeled products, including spreader stickers, check for tank mix 

compatibility. 

Crop tolerance: Crop tolerance is acceptable for all crops on the label, however phytotoxic 

response has not been evaluated for all possible rotational and tank mix combinations under all 

conditions. When possible, test on a small section of crops to ensure no phytotoxicity will occur 

under your conditions. 

GROUND APPLICATIONS

LEAP may be applied in ground equipment with quantities of water sufficient to provide 

thorough coverage of infested plant parts. The amount of water needed per acre will depend on 

crop development, weather, application equipment, and local experience. 

Do not spray when wind speed favors drift beyond the area intended for use. 

Avoiding spray drift at the application site is the responsibility of the applicator. The interaction 

of many equipment-and-weather-related factors determine the potential for spray drift. The 

applicator and the grower are responsible for considering all of these factors when making 

decisions. 

Mixing Recommendations: Important - do not add LEAP to the mix tank before introducing 

the desired quantity of water. Start the mechanical or hydraulic agitation to provide moderate 

circulation before adding LEAP. Add the desired volume of LEAP to the mix tank and continue 

circulation. Include rinse water from the container. Maintain the suspension while loading and 

spraying. Do not mix more LEAP than can be used in a 1-day period. Do not leave mixed 

material in the tank overnight. Rinse and flush spray equipment thoroughly following each use. 

Selection of fluid to flush the application system will depend on what type of mixture was used 

during the application period. Use a strainer no finer than 50 mesh in conventional spray 

systems. 

The physical compatibility of LEAP with other agricultural products should be evaluated before 

tank mixing for field use. Using a quart or larger jar, add the field proportional amounts of water 

volume and each product and mix well. If the materials remain mixed after 5-10 minutes, or can 

be re-mixed readily, then the materials are compatible for tank mixture. 

CAUTION: 

LEAP should not be used in combination with Comite®, Bravo®, Captafol, Captan (except seed) 

or Dyrene®. 

Spray Volume Recommendations: For conventional ground application, use at least 20 gallons 

of volume per acre.
