The Environmental Fate and Effects Division (EFED ) has reviewed the proposed new use for sp irotetramat on citrus trees speci fically located on residential plot s. The reg istrant, Bayer Cro pScienc e (BCS) , appl ied for this new residential use with l abe l information that i s summarized in Tabl e 1 below. Spirotetramat is already registered on citru s, but in agricultural settings , at the same single and seasonal application rate , and interval between applications, as the proposed label. f n a previous ecological risk assessment (ERA), EFED evaluated the ground, airblast, and aerial app lication s of spirotetramat on citrus as part of a national-level Section 3 New Use Assessment that also concerned a variety of other crops (D398764 , 2012). More recently , a Special Loca l Needs, Section 24(c) assessment was conducted for the control of the Asian citrus psyllid in California (D420542 , June 2014). For that action , BCS prop osed the removal of label lan guage previously proposed for the Section 3 New Use action that included citrus which stated that spirotetramat could be applied at bloom and the bee hazard label language also be removed.Currently, as part of th e previous Section 3 labe l o n citrus , s pirotetramat cannot be applied
w ithin 10 days prior to bloom, during bloom, o r until petal fall is complete

. BCS is prop os in g for this action on residential facility citrus , to maintain the label re strictio n s of application pri or to and during bloom as well as keeping bee h azard language intact from the Section 3 label on citrus. As there have been no new environmental fa te or ecological effects d ata reviewed by the Agency for spirotetramat s in ce the time of the Section 24(c) assess me nt , and given the fact that assessment as well as the Sec tion 3 n ew use assessment whic h included citrus would be protective of the risks id e ntified for this prop osed u se on c itru s trees in r esi dential fac ilities , a new ecological ri s k assessment is no t being co nducted to su pport this action. In s tead , please refer to th e previously mentioned assess ment s. 

### Summary of Use of Spirotetramat on Citrus in Residential Facilities
A summary of the u se informati on can be found below in 

### Tab le 1 for this proposed u se on residentially located citrus trees. The new product l 4ACP703 Insecticide/Mitic ide , containing 22.4% A.I. or 2 lb A.I./gallon, is a s uspension concentrate formu lat i on with the following application restriction: " D o not apply this product within 10 days prior to blo o m , during bl oom, or until petal fall is compl ete." The new product is intended for u se by commercial lic e nsed appl ic ators in outdoor re sidential areas on ly. The maximum single app lication rate is 0.1 6 lb a.i./A and a maxi m um of two appl icatio n s are a ll owed at th e maximum rate , u s ing a minimum interval between applications of 2 1 days. Onl y gro und app lication s are allowed. There are specific directions for s pray drift red uct ion and runoff manage ment. Amon g other targe t pests, there is the Asian citrus psyllid. According to the r eg istrant 's submiss ion , the Asian citru s psyllid "is a seri ous pest of all c itrus and closely related p lant spec ies in the Rutaceae fam il y suc h as o ran ge j asm ine and Indian curry leaf because it can transmit the disease huanglongbing (HLB ) w hen the pest feeds o n the plant' s leaves and ste m s
. HLB is the most devastating di sease of citru s in the world. There is no cure for th e disease and infected trees are remov ed and destroyed to preve nt further spread."

### EN V I RO NM E NT A L HAZARDS
"For Terrestrial Use: This pesticide is toxic to aquatic invertebrates and oysters. Do not apply directly to water, to areas where surface water is present , or to intertidal areas below the mean high water mark. This product may contaminate water through drift of spray in wind. Do not apply when weather conditions favor drift from treated areas. Drift and runoff from treated areas may be hazardous to aquatic organisms in neighboring areas. Do not contaminate water when disposing of equipment washwaters or rinsate.
Thi s chemical has properties and characteri stics associated wi th chemicals detected in ground water. The use of this chemical in areas where soils are permeable , particularly where the water table is s hallow, may res ult in ground-water contamination.
This product is potentially toxic to hon ey bee larvae through residues in pollen and nectar , but not to adult honey bees. Exposure of adult bees to direct treatment or residues on blooming crops can lead to effects on honey bee larvae. See the " Directi ons for Use" section of this label for specific crop application instructions that minimize risk to honey bee larvae."
