Foreword
This standard is one of the national crop pest investigation and forecast series.
This standard replaces GB/T 15791-1995 "Rhizoctonia investigation and forecast."
This standard and GB/T 15791-1995 compared to the main changes are as follows.
--- In the original "Rhizoctonia investigation and forecast" basis, adding the standard cover, preface; text tables all related investigations shift
To the appendix;
--- Summary grassroots investigators throughout many years of experience, it does not affect the accuracy of the survey, based on the specifications of the original investigation were appropriate sample size
Degree cut;
--- Sclerotia increased research and forecasting methods, provide a reliable basis and theoretical support for rice sheath blight prediction;
--- Normative annex to standardize the data format, ensuring data collection consistency; informative appendix as a guide throughout the investigation and rice sheath blight
Prevention and control to provide a reference.
The Standard Annexes A and C are normative appendix, Appendix B is an informative annex.
This standard is proposed and managed by the People's Republic of China Ministry of Agriculture.
This standard by the National Agricultural Technology Extension and Service Center is responsible for drafting, by the Jiangsu Provincial Plant Protection Station, Plant Protection Station of Guangxi Zhuang Autonomous Region, Jiangxi

Rice sheath blight forecasting technical specifications
1 Scope
This standard specifies the rice sheath blight sclerotia system condition survey method and survey a large area of \u200b\u200bforecasting data compilation and filing requirements
Techniques and methods.
This standard applies to rice sheath blight forecasting survey.
2 sclerotia survey
2.1 investigation time
Spring plowing paddy before.
2.2 Sampling Methods
Select the last year the incidence of light, medium and heavy three types of fields each a five-point sampling, each point 0.1m2.
2.3 Survey Methods
The thickness of 1cm of topsoil along with crop residues or be scooped (eg after winter flowers field survey, taking 5cm ~ 10cm thick topsoil)
Placed in the cylinder, add water, stir well, remove the surface scum, calculate the amount of sclerotia, converted into a residual amount of sclerotia per 667m2. Survey data entered in
Table A.1.
3 system disease survey
3.1, see the beginning of the investigation
3.1.1 investigation time
Starting from the end of tillering to find disease.
3.1.2 Survey Methods
Select local high fertilizer levels in previous years, the incidence of heavy early sowing, early planting plots, conducting investigations in Tanabe downwind or northwest corner, every 5d investigation
once.
3.2 Growth Survey disease
3.2.1 investigation time
From the beginning of the disease begin to rice milk stage.
3.2.2 Survey Methods
Select the early, middle, late interpolation type two fields each, linear sampling, each field survey of the incidence of 100 cluster cluster number and the number of trees, and the incidence of cluster computing
The incidence of strains, and select from 10 plexus severity classification (see Table B.1), calculated by the severity of the formula (1), the survey once every 5d, tune
Search results recorded in Table A.2.
A = Σ
(Bi × Bd)
M × Md ×
100 (1)
Where.
A --- severity;
Bi --- all levels of severity strain number;
Bd --- all levels of severity representative value;
M --- survey total number of trees;
Md --- severity of the most senior representative value.
