Abstract
The present invention relates to a kind of composition pesticide, contains active constituent pyraclostrobin, Metalaxyl-M, fludioxonil；Wherein the pyraclostrobin, Metalaxyl-M, fludioxonil weight ratio be 1~10:1~3:1；Composition can be applied to prevent and kill off rice seedling blight, seedling rot and enhancing rice root system；Enhance the method for rice root system under cryogenic conditions, method includes impregnating rice paddy seed with the composition pesticide, being handled rice plants root system, in rice plants cauline leaf progress spraying treatment or application rice plants root growth environment.
Description
Technical field
The invention belongs to technical field of pesticide, and in particular to one kind is effective with pyraclostrobin, Metalaxyl-M, fludioxonil
The synergetic pesticide composition of ingredient；Enhance the method for rice root system；Prevent and treat Achlya spp disease, the purposes of rice seedling blight.
Background technique
Applying chemical agent is to prevent and kill off one of most effective chemical means of corps diseases；With the new agriculture of not cross resistance
Medicine is come to prevent and treat corps diseases be a good solution；But one novel pesticide of exploitation needs to screen up to ten thousand at present
Compound, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, the speed that the upper weeds for being difficult to catch up with develop drug resistance；Other
Method such as crop structure adjustment, different pesticide rotation etc., in the actual operation process, be difficult to play apparent effect.
Reasonable chemical bactericide combination or mixture, which has, expands degrass spectrum, improves control efficiency, extends application period, subtracts
Few dosage reduces phytotoxicity risk, reduces residual, delays the advantages that generation and development of pathogenic bacteria resistance to drugs and drug resistance, institute
With develop it is suitable bactericide compounded or it is mixed be maximally efficient and economic one of the method to solve the above problems.
Exploitation new product fungicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
Root system is the general name of one plant of plant whole root, also referred to as root, and root system is the water in plant absorption root growth environment
Divide, the major organs of nutrient, inorganic salts；The major function of root has: make plant stability in the soil, storage energy resource, such as
Carrot and beet absorb moisture and minerals, round-trip stem transport moisture and minerals from soil；Root stores plant
Food (energy resource), these foods or used by root, or be digested absorption, postdigestive product is strangled skin tissue transmission
Part more than to plant soil；It can make the food of the mankind after the root harvest of some plants；Point of the plant hormone in root
It is synthesized in raw tissue, is passed up to aerial part through xylem, so that the growth of plant be promoted to send out the region between the heart and the diaphragm；Root system is impaired, directly
Affect the healthy growth of plant.
The root growth of rice has certain relationship with its temperature grown, and the seedbed management of rice is with " temperature adjustment, control water " for core
The heart is heated, is kept the temperature, the measures integrated application such as temperature control, guarantees 25-28 DEG C of temperature of shed, maximum temperature is no more than 30 DEG C；It holds
Good film-uncovering time, prevents high temperature burn seedlings.The root growth that low temperature usually seriously affects.Rice chilling injury is often referred to rice incident
Meet and give birth to minimum critical-temperature low temperature effect below, so as to cause rice is unable to normal growth and development and the underproduction.Chilling injury
It is that cold ground rice makees one of the major obstacle produced.Generally betide two periods: first is that the freeze injury that 4-5 month nursery stage occurs,
Both seedling blueness was withered.Second is that Honda phase " ear barren tip ", " empty grain " as caused by cool summer damage due to delayed growth and cool summer damage due to impotency, or even do not ear
Deng.After seeding stage is caused harm by low temperature, complete stool leaf color turns Huang, and plant lower part generates yellow leaf, and brown, partial blade is presented in some blades
Show white or yellow to yellow-white horizontal stripe spot.Daily mean temperature is met in 2-3 leaf seedling stage and is consistently less than 12 DEG C, is also easy to produce seedling rot.Have
Expert thinks that low temperature undergoes phase transition thermophilic crops biomembrane, this is initial reaction of the rice to chilling temperature, and damage to plants caused by sudden drop in temperature
Beginning because.Since the lipid-like substances of film solidify, film quality becomes gel state from liquid crystal state.The hydrocarbon chain of fatty acid is by unordered in film quality
Arrangement becomes ordered arrangement, changes biofilm thickness and external form, and due to the contraction of film, film surface generates duct, is cracked.It is raw
Object membrane permeability increase makes cell people's solute exosmose, hypopnea, the Toxics such as anaerobic respiration accumulation acetaldehyde, ethyl alcohol in cell
Matter causes cell to come to harm, and plant growth is suppressed.The low temperature continuous time is short or intensity is little, and this process is also reversible.Temperature
After degree rise switchs to normally, film mutually switchs to liquid crystal state again, and crop metabolism restores normally.If the low temperature intensity big duration is long, carefully
After birth is degraded to irreversible state, is led to cell and tissue die.Cause plant wilting or withered.China northeast rice workspace, China
Northern rice workspace, northwest rice workspace, Central China rice workspace, south China rice workspace, geographical location north and south locating for southwestern rice workspace are across 31
Latitude, height differ 2700m, and season of growth length great disparity, the ecological conditions such as light, temperature, water are different, form respective rice system
Degree, variety type and planting patterns, it is different that occurrence frequency, type, extent of injury are damaged to plants caused by sudden drop in temperature in various regions.
Summary of the invention
The technical problem to be solved in the present invention first is that by providing a kind of synergistic composition, reduce Pesticide use amount.
The second technical problem to be solved by the present invention is especially enhanced low by providing a kind of method of rice root system enhancing
The method of rice root system under the conditions of temperature slows down or avoids because low temperature is damage caused by rice, and rice restores normal raw after improving low temperature
Long ability.
