Abstract
The invention relates to a method for efficiently preventing and treating northern corn leaf blight, which is characterized by comprising the following steps: (1) blending 40% of coumoxystrobin tebuconazole and 25% of azoxystrobin according to a ratio of 1:1, and then adding water according to a ratio of 1:1000 to 15000, (2) using a high-clearance sprayer and a knapsack type sprayer to uniformly spray the leaf surfaces during the growth period, namely the flare opening period, of a susceptible northern corn leaf blight cultivar, (3) if an aviation work is needed, adding water into the blended 40% of coumoxystrobin tebuconazole and 25% of azoxystrobin according to a ratio of 1:20, namely 10 to 15 ml of 40% of coumoxystrobin tebuconazole, and 10 to 15 ml of 25% azoxystrobin are needed every 667m <2 >. According to the method provided by the invention, a formula of bactericide blending is adopted, when carrying out spraying during the flare opening period, the northern corn leaf blight can be efficiently prevented and treated.
Description
Technical field
The present invention relates to a kind of method of the high-efficiency prevention and control corn northern leaf blight, namely the method for mixture chemical bactericide control of maize leaf blight (be commonly called as cecospora spot, coal line is sick, dead leaf is sick) is adopted, and there is the strict time period medicament use age, belong to a kind of corn northern leaf blight reach Control Technology.
Background technology
From 2006, along with the popularity in first beautiful 335 districts northeastward of sense corn northern leaf blight kind, the problem of the corn northern leaf blight was more and more outstanding.The cultivation of domestic corn variety is also mainly with beautiful 335 be first target, and be that kind inbred line basis is cultivated in its male parent, female parent or similar U.S.A, the new varieties of majority cultivation also feel leaf blight.Also do not have good kind can substitute the improved seeds of first beautiful 335, so the plantation of large area susceptible variety brings immense pressure to plant protection work at present.Because weather conditions were suitable for leaf blight generation in recent years, the Northeast's weather is rainy with low temperature, the large weather of air humidity causes corn northern leaf blight outbreak of epidemic for main, and the loss of serious plot is up to 46%.The corn northern leaf blight continues mediumly to lay particular stress on generation for many years, brings serious threat to agricultural production.
Summary of the invention
The object of this invention is to provide a kind of method of the high-efficiency prevention and control corn northern leaf blight, namely adopt the formula of fungicide compounding, spray at corn trumpet period, can the high-efficiency prevention and control corn northern leaf blight.
Technical scheme of the present invention is achieved in that a kind of method of the high-efficiency prevention and control corn northern leaf blight, it is characterized in that concrete steps are as follows: 1), first by the SYP-3375 Tebuconazole of 40%, 25% Fluoxastrobin in 1:1 ratio mixture, and then be watered in 1:1000-1500 times of ratio, 2), utilize high-clearance sprayer, knapsack sprayer to carry out blade face even spraying when feeling corn northern leaf blight kind growth typhon mouth phase breeding time; 3) if need to adopt aviation boat equalization, the SYP-3375 Tebuconazole of 40% of mixture, 25% Fluoxastrobin are watered in 1:20 ratio, i.e. every 667m
2consumption 10 ~ 15 ml 40% SYP-3375 Tebuconazole+10 ~ 15ml 25% Fluoxastrobin.
Described spraying period is in corn growth stage-typhon mouth phase, dispenser when general late June or early July, when weather is beneficial to leaf blight generation, executes the technology of 1 time for interval 7-10 days again to control the generation of the corn northern leaf blight, in dispenser process, spraying first should be early unsuitable late.
Good effect of the present invention is that before breaking, leaf blight starts the idea of dispenser after generally occurring, and compares that to have control efficiency good with other products, and the lasting period is long, retrieve production loss obvious, for height sense and the kind feeling the corn northern leaf blight, average control efficiency can reach more than 83%, remarkable in economical benefits.Concrete test example is as follows:
One, control of maize leaf blight test
1. test material and method
1.1 test materials: corn variety KX3564, bactericide: 40% cloves Tebuconazole (domestic 10% SYP-3375,30% Tebuconazole), 25% Fluoxastrobin (domestic).
1.2 test methods: seeding and fertilizing and field management are equal to common agricultural farms.Start to apply overhead drug delivery of sprayer in the corn typhon mouth phase, spray 2 times, 7 days, interval, spraying time is according to field leaf blight incidence first, produces namely start dispenser as found that there is large spot, dispenser first the time generally in late June or early July.
2. pilot survey
2.1 diseases refer to investigation
To the experimental field corn northern leaf blight, a situation arises investigates, random 3 samplings, often 100 strains, calculates control efficiency.
2.2 survey product
Respectively process community diagonal 5 sampling during autumn harvest, get the long whole fruit ears of 10 meters of row, calculate Sampling Area and spike number, weigh after natural air drying threshing and working sample water content, be converted into standard weight 14% water content, calculate 100-grain weight and output for often.
3. test results and analysis
Cloves Tebuconazole+Fluoxastrobin mixture is at control of maize leaf blight successful as can be seen from Table 2, sprays 3 average preventive effects 31.8%, retrieves production loss and reach 63.7%, sprays 2 average preventive effects large 83.8%, retrieves production loss and reach 41.7%, successful.Research shows that cloves Tebuconazole+Fluoxastrobin is had outstanding performance with retrieving in production loss in control of maize leaf blight, and compared with other medicaments, after dispenser, the lasting period is long, dispenser safety, provides strong guarantee for retrieving production loss.
