Leaf seasonal febrile diseases and panicle blast investigation method:
Investigate incidence, disease refer to when leaf seasonal febrile diseases, panicle blast stable disease after medicine, and leaf seasonal febrile diseases are per 5 points of samplings of cell, every point
50 plants of investigation, every plant of investigation boot leaf and the following two panels leaf of boot leaf;Every 50 fringes of investigation of panicle blast, record morbidity strain and severity,
Calculate disease index and protection effect.
Leaf pest grade scale is as follows:
0 grade:Disease-free spot;
1 grade:Leaf spot lesion is less than 5, and length is less than 1cm;
3 grades:Leaf spot lesion 6~10, part scab length are more than 1cm;
5 grades:Leaf spot lesion 11~25, part scab is linked to be piece, accounts for leaf area 10%~25%;
7 grades:Leaf spot lesion more than 26, scab is linked to be piece, accounts for leaf area 26~50%;
9 grades:Scab is linked to be piece, accounts for leaf area more than 50% and whole leaves are withered.
Panicle blast grade scale is as follows:
0 grade:It is disease-free;
1 grade:Loss less than 5% (indivedual branch stalk morbidities) per fringe;
3 grades:Loss 6%~20% (morbidity of 1/3 or so branch stalk) per fringe;
5 grades:Loss 21%~50% per fringe (fringe neck or main shaft morbidity, grain half are flat);
7 grades:Loss 51%~70% per fringe (fringe neck is fallen ill, big portion's shrivelled kernel);
9 grades:Loss 71%~100% per fringe (fringe neck is fallen ill, and causes dead ears).
Preventive effect calculation formula:
Diseased plant rate (%)=diseased plant number/investigation strain number × 100
