Stress at one point in a season may have indirect consequences on fibre quality

Cotton Bunchytop Survey - Winter 2011

This survey conducted by CCA members will help to define the potential risk for next season from Cotton Bunchy Top disease and also to help alert growers to these risks.

Responses from this survey will be used for research and extension purposes. Data will be amalgamated and individual enterprises and survey respondents will not be identified in reporting.

It is intended consultants will complete a separate survey for each individual farm or enterprise. Once one farm is submitted users will be forward to a confirmation page that gives them the option of entering another farm.

Section 1 should be completed after surveying fields and non-crop areas to identify areas of potential hosts (Ratoon /volunteers & broadleaf weeds).

Section 2 should be completed after interviewing grower. Survey participants are encouraged to talk with their growers about the risks of Cotton Bunchy Top to yield and the risk factors including areas identified as having over winter hosts.

SECTION 1 - RISK - Assesment Based on Farm Visit

Q1: Based on farm visit, please indicate thickest infestation of overwinter hosts (ratoons/volunteers from last season and broadleaf weeds) seen per hectare. (eg. rare = the worst field for hosts has <1 plant/hectare). *

	U. Unsure- Not done	0. None - Not seen	1. Rare <1/ha	2. Common 1-10/ha	3. Numerous >10/ha
Volunteers, Ratoons
Broadleaf Weeds

Q2: Based on farm visit, for On Farm and Off Farm please indicate the thickest infestation of overwinter hosts (ratoons/volunteers from last season and broadleaf weeds) seen per 100m. (eg. rare = the worst area for hosts in a non-field area has 1 plant/100m.) Off farm refers to other areas that might pose a risk, however are not part of the farm (eg. channels not controlled by the farm, near by public roads, neighbours farm/fields). *
