A kind of preparation method of prevention bradysia odoriphaga pesticide

This case is divisional application, original application it is entitled：A kind of side for the pesticide preparing prevention bradysia odoriphaga using biogas slurry The applying date of method, original application is：2016-01-28, original application application No. is：201610057665.5.

Technical field

The present invention relates to technical field of pesticide, more particularly to a kind of preparation method of prevention bradysia odoriphaga pesticide.

Background technology

Bradysia odoriphaga is the larva of Diptera category Bradysia odoriphaga.Bradysia odoriphaga foraging territories are wider, can endanger Liliaceae, Chenopodiaceae, 30 various vegetables such as composite family, Curcurbitaceae, Cruciferae, Umbelliferae, the wherein aggrieved most serious of leek.The master that leek is planted in China More universal, occurring area up to 90% occurs for producing region, the worm.Leek field attacked trees rate causes fragrant-flowered garlic generally 20% or more Dish production loss is between 30%~80%.Statistics shows the probability that is infected by bradysia odoriphaga of leek after growth 2 years up to 80% Left and right, in particular with the increase of anti-season leek and hotbed chives production, leek is increased year by year by the probability that bradysia odoriphaga infects, some ground Area nearly reaches 100%.Bradysia odoriphaga is a kind of subterranean pest-insect of stubbornness, is the crushing pest for endangering leek growth.Bradysia odoriphaga larva master It is clustered in underground, on the bulb of leek underground part, moth food bulb and tender shoots.After leek is aggrieved, commodity value is gently then influenced, It is heavy then leek bulb is caused partly or wholly to rot, make the ground blade of leek it is thin and weak it is withered and yellow, wilt and rot or even dead in flakes, Greatly compromise the interests of fragrant-flowered garlic agriculture.

A large amount of generations of bradysia odoriphaga are rapid plus its breeding, seriously affected the economic benefit of leek.It is carried to effect a radical cure bradysia odoriphaga Root is gone out and has dialled native Disinsection method, fly net and sugar-vinegar liquid trapping method, foundation earthing, the decomposed deep placement of organic fertilizer, pick root at crop rotation Cool soil, plant ash pull out dry, bioanalysis etc., and still, these methods have heavy workload, and efficiency is low, and input cost is high, goes out except fragrant-flowered garlic The deficiencies of less effective of maggot.Killing bradysia odoriphaga at present, quickly and effectively method is still chemical method.The profession of national approved applications is anti- The drug of bradysia odoriphaga is controlled mostly based on the strong phoxim of absorbability (organophosphorus insecticide) and chlopyrifos, but the harvest time of leek It is short, not up to safety interval of pesticide pollution when leek is gathered in, and fragrant-flowered garlic agriculture has also been unable to get using the quantity and frequency of such drug Effect control；While killing bradysia odoriphaga, soil causes its degradation speed slow the strong adsorptivity of pesticide, on the leek of some areas Excessive pesticide residues also tend to be absorbed into vivo by leek.With the application of such pesticide, bradysia odoriphaga is also more next to the resistance of pesticide It is stronger, force fragrant-flowered garlic agriculture go to apply more high poison in violation of rules and regulations, more effective 3911,1605 etc. pesticides form vicious circle, lead to leek agriculture Medicine residual is exceeded.The leek after bradysia odoriphaga is killed due to the use of highly toxic pesticide, growth and development is unaffected, meanwhile, in leek Can not also it differentiate in appearance, therefore, often this " malicious leek " is eaten in daily life, malicious leek event takes place frequently in recent years, even Continuous malicious leek exposure event causes human body greatly to injure severe patient's even threat to life so that consumer " talks fragrant-flowered garlic color Become ", seriously affect the economic interests of vegetable grower and the food security of consumer.

In addition the applications of pesticide have been arrived in natural environment, although having achieved the purpose that want, also bring pollution simultaneously Problem.If environment and Pesticide Residues amount are exceeded, the mankind, other organisms or even the entire ecosystem can be caused Harmful effect.Pesticide enters after natural ecological environment, can enter human body by approach such as respiratory tract, alimentary canal, skins.Such as Fruit reagent toxicity is larger, it is possible to cause acute poisoning or subacute poisoning, or even cause life danger.Although some medicaments Acute toxicity is little, but if property is stablized, is not easily decomposed, disappears after use, will remain in water, air, crops, agricultural production In product or aquatic products, livestock products, human body is eventually entered into, slow poisoning is caused.Meanwhile pollution by pesticides can also cause other biological Poisoning is even dead, so that destroying the ecological balance, it is therefore necessary to residual and the pollution for controlling pesticide, to reduce to human society Influence and harm.

In addition, the yield of China's kitchen garbage is increasing in recent years, estimation account for the 50% of domestic waste total amount with On；It endangers the appearance of the city health for directly affecting city, leads to insect pest, the plague of rats or even transmission；More seriously, part Kitchen garbage is unprocessed and is processed into " gutter oil " into market or flows to underground farm as feed, seriously threatens people The life and health of the people.The main processing ways of kitchen garbage include both at home and abroad at present：Burning, compost, landfill, Fodder making and detest Aerobe fermentation.A variety of different processing methods and equipment have also been invented in people.Such as application number：201010224280.6 specially The sharp entitled integrated conduct method using kitchen garbage gas system fertilizer.Application number：201110339482.X patent name is a kind of Municipal organic waste combined anaerobic treatment process and equipment.Application number 201210532285.4, the recycling of patent name kitchen garbage Using method etc. be disclose will rubbish carry out anaerobic fermentation after be divided into biogas, biogas slurry and biogas residue handle application respectively.

Biogas slurry is otherwise known as anaerobic fermented liquid, is the various organic matters such as people, animal excrement and agricultural crop straw, weeds through anaerobism Liquid residue after fermentation.The conventional nutrients that crops need in biogas slurry have the multiple elements such as nitrogen, phosphorus, potassium, magnesium, calcium few Amount trace element, active organic component have the plant hormones such as humic acid, heteroauxin, lactic acid bacteria, gibberellin, the basic element of cell division, B Family vitamin has B1, B2, B5, B6, B11, B12, also contain there are many amino acid, protein, hydrolase and a variety of inorganic acids and The organic molecules such as certain antibiotic, coordinative role is present in the form of available nutrient and biological pesticide mutually between these ingredients In biogas slurry, it directly can rapidly be absorbed and kill harmful levels of pathogens and worm's ovum and promote the growth of the plants such as crops and flowers, Therefore biogas slurry could also say that a kind of medicine fertilizer.

But these effective component contents are relatively low in biogas slurry, for concentration generally 10% or so, remaining is all free state Water and plant fiber, silt, bacterium, clay, colloid, pesticide residue, suspended matter and the organic matter containing fishy odor, are used as Often dosage is big when Crop fertilizer, and effect is poor, thus peasant is unwilling to make fertilizer using biogas slurry more.If biogas slurry is arranged everywhere It puts, not only waste of resource, but also pollutes environment, it is of high cost if handled by sewage, and be difficult to handle.Crops and flower The plants such as grass directly apply this biogas slurry, do not meet agricultural health standard, can cause the secondary pollution in farmland, can also be to growth conditions And growing environment adversely affects, also the amount of directly this biogas slurry of application is also bigger, and this certainly will increase biogas slurry Transportation cost and labor intensity still more use fertile season, biogas slurry that cannot be fully used, the unordered discharge of extra biogas slurry non- The pollution and waste for causing environment need further processed in order to avoid transmission and soil pollution as fertilizer Rear is handled to can be used.

The great attention of the leek safety in production of people is aroused in poisoning caused by a large amount of excessive problems of pesticide residue.It is many More agriculture practitioners also recognizes the seriousness of such event, also has lofty ideals for finding environmentally friendly method, also work out The biological agent of some prevention bradysia odoriphagas, but since cost is higher, effect does not obtain on a large scale not as good as reasons such as chemical pesticides It is effective to promote and apply.

Therefore, how it is cheap effectively kill bradysia odoriphaga, improve the safety of food, people made to trust that edible leek is ability One of the important topic of field technique personnel research.And the generation of kitchen garbage, current environment ability to bear is seriously tested, it will Classify after rubbish timely processing and rationally utilize, turns waste into wealth extremely urgent.
