| IPM Compatibility: |
PER REQUESTER: VERY GOOD IPM FIT; WILL PROVIDE THE UC IPM GUIDELINES FOR ARMYWORM ON RICE; WORK IS UNDERWAY TO UPDATE THE GUIDELINES AND THE SCOUTING METHODS; CURRENT WORK ON PHEROMONE TRAPPING THE ADULTS HAS LEAD TO PREDICTIONS OF ARMYWORM INFESTATIONS; TOXICITY TO BENEFICIALS IS NOT AN ISSUE WITH CA RICE GROWING PRACTICES; THE STEWARDSHIP PRACTICES PROVIDE MITIGATION WHEN ADDRESSING ENVIRONMENTAL CONCERNS; THE PURPOSE IN PURSUING FOLIAR APPLIC TO RICE IS FOR ARMYWORM CONTROL - A PEST WITH VIRTUALLY NO EFFECTIVE PESTICIDES UNTIL METHOXYFENOZIDE WAS ISSUED AS A SECTION 18 EMERGENCY EXEMPTION; THE CA RICE INDUSTRY IS TAKING A PROACTIVE APPROACH TO RESISTANCE MANAGEMENT FOR LONG-TERM USE OF ALL ALTERNATIVE INSECTICIDES TO CONTROL ARMYWORM; CHLORANTRANILIPROLE WOULD BE A GOOD IPM FIT AS AN ALTERNATIVE ARMYWORM INSECTICIDE:07/19
|
| Reasons for need: |
ARMYWORM (TRUE & WESTERN YELLOW- STRIPED) MYTHIMNA (= PSEUDALETIA) UNIPUNCTA AND SPODOPTERA PRAEFICA; THE TRUE ARMYWORM IS MOST PREVALENT IN CA RICE AND DIFFICULT TO CONTROL; CHLORANTRANILIPROLE IS A PRE-PLANT SOIL APPLIED INSECTICIDE FOR EARLY SEASON INSECT PESTS SUCH AS RICE WATER WEEVIL; THE SECTION 3 LABEL PROHIBITS FOLIAR APPLIC TO RICE; THIS IS A REQUEST TO EXPAND THE USE TO FOLIAR APPLIC TO RICE FOR ARMYWORM CONTROL; ALTERNATIVE INSECTICIDES ARE INEFFECTIVE AND HAVE ADDITIONAL LIMITATIONS WITH HERBICIDE APPLIC; METHOXYFENOZIDE IS AN IGR USED AS A SECTION 18 SINCE 2015; CONCERNS EXIST ABOUT METHOXYFENOZIDE BUILDING RESISTANCE

| Requesting State(s): |
CA:Firoved, R ;
|
| PCR Use Pattern: |
USE PREVATHON INSECT CONTROL; MAKE NO MORE THAN 2 FOLIAR APPLIC OF 20 FL OZ PRODUCT (0.067 LB AI)/A, FROM EARLY TILLERING TO PANICLE INITIATION, AND UP TO FLOWERING; 7-DAY INTERVAL (IF A SECOND APPLIC IS NEEDED), 1-DAY PHI; BEGIN APPLICATIONS WHEN FIRST SIGNS OF FEEDING DAMAGE APPEAR OR WHEN THRESHOLD LEVELS OF FEEDING DAMAGE OCCUR; APPLY BY AIR OR GROUND (MINIMUM 5 GPA); PREPLANT APPLIC OF CHLORANTRANILIPROLE HAVE A WATER HOLDING REQUIREMENT OF 14-DAYS; ASSUME THAT WOULD CARRY FORWARD TO FOLIAR APPLIC, AND POSSIBLY INCREASE; WILL PROVIDE EXAMPLES OF WATER HOLDING REQUIREMENTS FOR CALIFORNIA RICE; THE WATER HOLDING REQUIREMENTS ARE IN PLACE FOR EFFICACY AND FOR PESTICIDE DEGRADATION TO ACCEPTABLE LEVELS BEFORE RELEASE FROM THE FIELD; THE ADDITION OF AGRICULTURAL ADJUVANTS MAY IMPROVE INITIAL SPRAY DEPOSITS, REDISTRIBUTION AND WEATHER-ABILITY; SELECT ADJUVANTS THAT ARE CERTIFIED BY CHEMICAL PRODUCERS & DISTRIBUTORS ASSOC. AND REGISTERED FOR THE SPECIFIC USE PATTERN
