Application Example
In July, 2016, the test of pesticide effectiveness is carried out on paddy rice, be banded sclerotial blight early stage during test, there is scab, the vertical volume of rice on blade
The medium generation of leaf snout moth's larva, medicament formula, 5% chlorobenzene ether amide suspending agent, 5% fluorobenzene ether amide suspending agent, 5% Buprofezin from more than
Wettable powder.Second dispenser after lOd is spaced after first time dispenser, 15d investigation insecticidal effects and sterilization after second dispenser
Effect.
The investigation method of banded sclerotial blight is:Each cell selects 5 fixed point observations, per 2 clumps of paddy rice that disease is investigated before dispenser
Refer to, the sick leaf rate of 15d investigation, disease index, calculate the prevention effect of each medicament after last time dispenser.
Banded sclerotial blight grade scale:
0 grade:It is disease-free；
1 grade:Leaf spot lesion is less than 5, and length is less than 1 cm；
3 grades:Leaf spot lesion 6-10, part scab length is more than 1 cm；
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% or full leaf is withered.
Disease index=[∑ (the sick number of sheets × relative series)/(investigation total number of sheets × total series)] × 100
Prevention effect (%)=[1- (CKoSick index × pt1Sick index/CK1×ptoSick index)] × 100
CkoFor the disease index of the front check plot of dispenser；ck1For the disease index of check plot after dispenser；
ptoFor the disease index before treatment region dispenser；pt1For the disease index of dispenser post processing zone；
The investigation method of rice leaf roller is:15d investigation leaf roll number, calculates prevention effect after last time dispenser.
Leaf roll rate (%)=(investigation leaf roll number/investigation total number of sheets) × 100
Prevention effect (%)=[(blank district leaf roll rate-treatment region leaf roll rate)/blank district leaf roll rate] × 100
The chlorobenzene ether amide of table 1 or fluorobenzene ether amide, Buprofezin test of pesticide effectiveness result
From test, chlorobenzene ether amide or fluorobenzene ether amide and Buprofezin are (after compounding, to rice sheath blight disease and rice leaf roller
Have good prevention effect, after second dispenser 15d to the preventive effect of banded sclerotial blight and rice leaf roller all more than 85%.Peasant one
Secondary medication can effectively prevent and treat banded sclerotial blight and rice leaf roller, because chlorobenzene ether amide or fluorobenzene ether amide and Buprofezin (have height
Effect Uptake and translocation, can significantly extend the lasting period of medicament, reduce times for spraying, reduce planting cost.
