Abstract

The present invention provides a compound preparation of an imidacloprid insecticidal agent, particularly imidacloprid-fenobucarb emulsifiable concentrate. The imidacloprid-fenobucarb emulsifiable concentrate belongs to the pesticide technical field and is prepared by that imidacloprid as basal materials, fenobucarb as auxiliary materials, and auxiliary agents, such as an emulsifying agent, dimethylformamide, orthoboric acid, toluene, etc. are mixed into a tank according to a certain weight ratio and sedimentated for a certain time through a sedimentation tank. The compound pesticide can raise drug effects, can enlarge a disinsection range, can prolong the service lives of imidacloprid and fenobucarb, can reach 94.7% of control efficiency, can greatly reduce the production cost, can save peasant labor, can increase yield by 30 kilograms per mou, has the advantages of low toxicity, harmless and high safety, and is a favorable insecticidal agent.

Description

A kind of Pesticidal combination that contains Imidacloprid and Bassa

The present invention be a kind of Imidacloprid and Bassa of containing as the Pesticidal combination of active ingredient, particularly relate to its cream preparation.

The English name of Imidacloprid: Lmidacloprid

Empirical formula: C ₉H ₁₀CIN ₅O ₂

The insecticide that Imidacloprid is a kind of efficient, low toxicity, interior absorption is strong, its mechanism of action uniqueness is the acceptor of nicotinic acid acetylcholinesterase.Pierce-suck type, scratching mouthparts insect such as aphid, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof there is special efficacy.Diptera and coleopteran pest also there is certain effect.But the Imidacloprid formulation is single, mostly is 10% wetting powder, and complex manufacturing, the cost height costs an arm and a leg, is difficult to accept for the peasant.Simultaneously, dosage is few because the Imidacloprid insecticidal activity is high, and control water rice hopper effective dose is 1 gram/mu only.The formulation of high-load often is difficult to the realization dispenser when using even, thereby cause its whole control efficiency to descend, and influences giving full play to of Imidacloprid drug effect.

In order to give full play to efficient, the long-acting characteristics of Imidacloprid, the objective of the invention is to provide a kind of complex preparation-a kind of Pesticidal combination that contains Imidacloprid and Bassa of Imidacloprid, use that this composition is not only same efficient, low toxicity and better effects if, residual lower, and production cost declines to a great extent.

The present invention realizes like this, Pesticidal combination of the present invention, still be that base stock is composite in addition with the Imidacloprid, it takes Imidacloprid, Bassa and auxiliary agent newborn 100# of farming or emulsifier (agricultural newborn 600#+602 emulsion+2201 emulsions), dimethyl formamide, boric acid or citric acid, toluene is equipped with the back by 1～10: 1～50: 8～15: 5～20: 1～5: 30～60 particularly 1: 10～28: 4.8～9: 5～16: 1.2～3.5: 18～50 weight successively and drops in the retort mixed, stir and got mixture in 2 hours, branch jar packing then gets product sedimentation in the above-mentioned gained mixture input subsider more than 24 hours.Solution of the present invention mainly is to carry out composite with Bassa to Imidacloprid, why is selecting Bassa composite dose of Imidacloprid? this is to belong to carbamate chemicals for agriculture because of Bassa, the mechanism of action of carbamate chemicals for agriculture is acetylcholinesterase in the inhibition insect bodies, blocks normal nerve conduction, cause the imbalance of whole physiology course, insect is poisoned to death.This class agricultural chemicals generally has short characteristics of the fast longevity of residure of effect, and Imidacloprid is a kind of nitro-methylene-type agricultural chemicals, use this agricultural chemicals all very stable in acid medium, after composite, do not produce chemical reaction, and because the mechanism of action of these two kinds of agricultural chemicals is different fully, so can make up for each other's deficiencies and learn from each other the tangible synergy of the mutually beneficial generation of advantage.

The English name of Bassa: Fenobucarb

Empirical formula: C ₁₂H ₁₇NO ₂

As mentioned above, Bassa also is a kind of multiple-effect, low toxic pesticide, its mechanism of action is the acceptor of acetylcholinesterase, be mainly used in the control sanitary insect pest at present, on agricultural, be mainly used in paddy rice and prevent plant hopper, leafhopper, rice leaf roller etc., quick-acting is good, but action time is shorter, behind the different agriculture chemical compounding of these two kinds of mechanism, can improve drug effect, enlarge the desinsection scope, can also prolong the service life of these two kinds of single agent, reduce production costs, primary Calculation according to trial production, produce one ton composite dose, its cost is than 1.2 ten thousand yuan more than of Imidacloprid list agent reductions per ton, the preproduction plant hopper test of pesticide effectiveness, and 14 days control efficiency reaches 94.7% after the dispenser, comparison is high 8 percentage points according to the control efficiency of medicament buprofezin, and per season paddy rice only need spray once, only 40 milliliters of every mu of consumptions are amounted to 1.72 yuan of RMB, easily accept for the peasant, for the peasant saves the labour, this Pesticidal combination belongs to low-toxin farm chemicals through probationary certificate, to the person poultry harmless again, safe in utilization, be convenient to large tracts of land and promote, and make every mu of rice field volume increase more than 30 kilograms, and three-waste free discharge in producing, social benefit and economic benefit develop simultaneously, and are a kind of excellent insecticide.

Embodiment 1: get 450 kilograms of 25 kilograms of Imidacloprids, 250 kilograms of Bassas, agricultural newborn 100#120 kilogram, 125 kilograms of dimethyl formamides, 30 kilograms of boric acid, toluene and go into jar mixed, evenly stirred 2 hours, branch jar packing then gets product sedimentation in the above-mentioned gained mixture input subsider more than 30 hours;

Embodiment 2: get 5000 kilograms of 100 kilograms of Imidacloprids, 2800 kilograms of Bassas, agricultural newborn 600#300 kilogram, 300 kilograms of 602 emulsions, 300 kilograms of 2201 emulsions, 1600 kilograms of dimethyl formamides, 350 kilograms of citric acids, toluene totally 10 tons of 0 750 kilograms of raw materials and auxiliary agent be mixed into jar stir treated in 2 hours evenly the back drop in the subsider sedimentation 36 hours Pesticidal combination finished product of the present invention divides a jar packing.
