Monsanto comments to the SAP

# Performance Inquiries from 2011 - 2013  

## Similar number of performance inquiries each year but geographical distribution has varied from year

- to
- year  

## Total acreage impacted about 50,000 acres (<0.2% of the product acres)  

## Almost all performance inquiries continue to involve single trait technologies (>95%)

# Performance Inquiry Trends and Strategy for BMPs  

## Typically affect a single field per farm with a history of at least three years of corn

- on - corn planting  

## Indicative of performance inquiries arising independently from a similar set of conditions, rather than spreading from a number of focal points  

## Supports a management approach that focuses on problem fields and considers both IRM and CRW population control

# Growers instructed to use one of three options on performance inquiry fields BMP options chosen to meet requirements for responding to “populations of concern” but conservatively were implemented on all performance inquiry fields  

### Rotate to soybeans or alternative crop  

### Plant Genuity ® 

### SmartStax ® 

### RIB Complete TM 

### corn  

### Continue to manage beetles  

### Plant YieldGard VT Triple ® 

### or Genuity ® 

### VT Triple PRO TM 

### and either: 1) 

### Use a soil

- applied insecticide at planting to control larvae 2) 

### Chemigate Brigade or Lorsban to control larvae 3) 

### Use Brigade to control beetles and reduce egg laying

# Performance and Follow - up of BMPs  

## >95% of BMPs resulted in excellent control and minimal CRW populations; these fields are being treated as reset  

## Where BMPs did not provide satisfactory control, fields are being rotated to alternative crops (if at all possible) or non

Cry3Bb1 products  

## Similarly, any new performance inquiry fields that involve SmartStax are being rotated to alternative crops (if at all possible) or non

- Cry3Bb1 products; other new performance inquiries are addressed with any of the full set of BMPs

15 Monsanto comments to the SAP

# IRM strategy for high CRW fields  

## The same set of BMPs are being recommended for all corn

on - corn plantings in high pressure areas  

## Continuing to increase availability of pyramided technologies ( SmartStax RIB hybrids) in high CRW pressure areas  

## Robust solution to compliance issues: in 2013, all Monsanto Bt products (single and pyramided traits) were available in RIB format in the Corn Belt
