Reduced Risk Status: |
THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
|
IPM Compatibility: |
Per Requester: Very Good Fit; Phytophthora species are well known to develop resistance to site specific fungicides so more than one active ingredient is needed to alternate. Currently, Segovis is registered for use on non-bearing plants but other registered products do not control Phytophthora:08/23; CA/Our nursery greenhouses (non-bearing) plants need this badly, as stated above... for resistance management:08/23; GOOD FIT: REGISTRATION WOULD OFFER AN UNIQUE MODE OF ACTION: NCR
|
Reasons for need: |
Phytophthora root rot; Segovis is registered for non-bearing plants but there is no other product for Phytophthora registered for resistance management. Plantlets may originate from the field and Phytophthora is commonly encountered.

PCR Use Pattern: |
Use Subdue at 21.7 ml/1000 sq. ft; Drench application; 1 application; apply as a drench at planting/transplanting in greenhouse; PHI: 1 day; Per mfg, applications are not to be made made in the field and that the “at transplant” refers to the planting of plantlets into pots while in the greenhouse; the plantlets would be planted into their final container, a drench applied, grown for several weeks in the greenhouse and then sold to consumers at retail:09/23

Comments: |
Mfg supports as "researchable, residue & e/cs data needed and applications are not to be made made in the field and that the “at transplant” refers to the planting of plantlets into pots while in the greenhouse; the plantlets would be planted into their final container, a drench applied, grown for several weeks in the greenhouse and then sold to consumers at retail:09/23/sb; commodity changed from Strawberry (GH) to Strawberry (GH Transplant):09/23/sb; Possible ChemSAC(?):09/23/sb; EPA Green 12/23; this study will be covered by ChemSAC for residue so the status of Researchable, Residue & E/CS Data needed is being updated to "tolerance to be pursued with no data proposal/petition" and once the E/CS protocol is signed it can be updated to E/CS data ongoing:01/24/sb; Status updated to ECS ongoing 05/24/drs;
