Foray - 48B

Foray® 48B is an aqueous suspension formulation of Bacillus thuringiensis subsp. kurstaki (Btk strain ABTS-351); with a potency of 10,600 Cabbage Looper Units [CLU] per milligram). (This is equivalent to 48 CLU per US gallon, or 12.7 CLU per liter.) Foray 48B was specifically developed to protect forests from harmful defoliation caused by destructive caterpillar pests. Btk is a unique, naturally occurring bacterium that affects only caterpillars and, because of the unique chemistry of the caterpillar’s gut, Foray 48B Btk is highly selective in its activity. It has minimal environmental impact and it will not harm other types of insects, fish, birds or mammals.

Caterpillars must ingest Foray 48B for it to be effective. When forest health professionals determine the timing is right, certified applicators apply Foray 48B to caterpillar-infested trees and forests. Shortly after Foray 48B is eaten, it causes a reaction in the caterpillar’s gut; the caterpillar quickly stops feeding, the gut ruptures and the caterpillar dies within a day or two.

Foray 48B can be applied either neat (undiluted) or diluted with water depending on program needs and application criteria; it should always be applied according to label directions for best results. Timing of Foray 48B spray is critical as well as good spray coverage. As caterpillars do not hatch and develop all at the same time, sometimes a second application may be required. Foray 48B is more effective on younger caterpillars, so more than one application may be needed to control later emerging caterpillars. A second spray may also be required when caterpillar populations are extremely high. Various caterpillar species have varying levels of susceptibility to the Btk toxins; consequently there is a wide range of dosages identified on the label to ensure that effective control of the target species is obtained. (See below)

Foray 48B has been certified for use in Certified Organic Production under the National Organic Program (NOP) and it is also listed by the Organic Materials Review Institute (OMRI).

Foray - 76B

Foray® 76B is a high potency, aqueous suspension formulation of Bacillus thuringiensis subsp. kurstaki (Btk strain ABTS-351; potency of 16,700 Cabbage Looper Units [CLU] per milligram) that was specifically developed to protect forests from harmful defoliation caused by specific caterpillar pests. Btk is a unique, naturally occurring bacterium that affects only caterpillars and, because of the unique chemistry of the caterpillar’s gut, Foray 76B Btk is very selective in its activity. Foray 76B has minimal environmental impact and it will not harm other types of insects, fish, birds or mammals.

Caterpillars must ingest Foray 76B for it to be effective. When forest health professionals determine the timing is right, certified applicators apply Foray 76B to caterpillar-infested trees and forests. Shortly after Foray 76B is eaten, it causes a reaction in the caterpillar’s gut; the caterpillar quickly stops feeding, the gut ruptures, and the caterpillar dies within a day or two.

 

Foray 76B can be applied either neat (undiluted) or diluted with water depending on program needs and application criteria; it should always be applied according to label directions for best results. Timing of Foray 76B spray is critical as well as good spray coverage. As caterpillars do not hatch and develop all at the same time, sometimes a second application may be required. Foray 76B is more effective on younger caterpillars, so more than one application may be needed to control later emerging caterpillars. A second spray may also be required when caterpillar populations are extremely high. Various caterpillar species have varying levels of susceptibility to the Btk toxins; consequently there is a wide range of dosages identified on the label to ensure that effective control of the target species is obtained. (See below.)

 

Note: Foray 76B differs from Foray 48B in that Foray 76B was initially developed as a higher potency, more concentrated formulation, primarily used to control defoliators such as Budworms and Tussock Moths in coniferous forests. Foray 76B can be used to control lepidopteran defoliators in deciduous forests too, but caution must be taken to ensure that adequate atomization and foliar deposition occurs. Traditionally higher volumes (with slightly larger droplet sizes) are applied to control defoliators in deciduous forests

Foray XG - For Ground Applications Only (USA)

Foray® XG is an aqueous suspension formulation of Bacillus thuringiensis subsp. kurstaki (Btk strain ABTS-351); with a potency of 10,600 Cabbage Looper Units [CLU] per milligram). (This is equivalent to 48 CLU per US gallon, or 12.7 CLU per liter.) Foray XG was specifically developed to protect urban trees and shrubs from harmful defoliation caused by destructive caterpillar pests. Btk is a unique, naturally occurring bacterium that affects only caterpillars and, because of the unique chemistry of the caterpillar’s gut, Foray XG Btk is highly selective in its activity. It has minimal environmental impact and it will not harm other types of insects, fish, birds or mammals. It is ideal for use to protect shade trees and shrubbery in an urban environment.

Caterpillars must ingest Foray XG for it to be effective. When forest health professionals determine the timing is right, arboriculturists and certified applicators apply Foray XG to caterpillar-infested trees and shrubs. Shortly after Foray XG is eaten, it causes a reaction in the caterpillar’s gut; the caterpillar quickly stops feeding, the gut ruptures, and the caterpillar dies within a day or two.

Foray XG can be diluted with water at various rates depending upon the method of application chosen (hydraulic sprayer, powered mist blower, pump sprayer, etc.); it should always be applied according to label directions for best results. Timing of the Foray 48B spray is critical as well as good spray coverage. As caterpillars do not hatch and develop all at the same time, sometimes a second application may be required a few days later. Foray 48B is more effective on younger caterpillars, so more than one application may be needed to control later emerging caterpillars. A second spray may also be required when caterpillar populations are extremely high. Various caterpillar species have varying levels of susceptibility to the Btk toxins; consequently there is a wide range of dosages identified on the label to ensure that effective control of the target species is obtained. (See below.)

Foray XG has been certified for use in Certified Organic Production under the National Organic Program (NOP) and it is also listed by the Organic Materials Review Institute (OMRI)
