Abstract
The present invention relates to an imidacloprid preparation and application of nonylphenol polyoxyethylene ether in said imidacloprid preparation. The described pesticide includes surfactant and imidacloprid, their weight mixing ratio is 1:10-10:1. Said invention uses nonylphenol polyoxyethylene ether as surfactant, so that it can produce good synergistic effection.
Description
Technical field
The present invention relates to the application in this Imidacloprid preparation of a kind of Imidacloprid preparation and polyoxyethylene nonylphenol ether.
Background technology
Agricultural chemicals tends to add certain surfactant in the preparation processing process, as missible oil, microemulsions etc. on the one hand make agricultural chemicals in use can form uniform and stable dilution in water, are convenient to spray; On the other hand, can be crop, insect or weeds surface are wetting fully, soup is contacted with these targets fully, with the assurance drug effect, yet, the always not simple positive correlation of the result of use of agricultural chemicals and wetability, promptly always wetability is not good more, and the result of use of agricultural chemicals is good more.Surfactant joins that the influence to drug effect is complicated in the pesticidal preparations, and some can increase the result of use of agricultural chemicals, and some is then opposite.Imidacloprid is a kind of nitro-methylene-type systemic insecticide, it is the acting body of nicotinic acid acetylcholinesterase acceptor, it is malfunctioning to disturb the pest movements nervous system that chemical signal is transmitted, no cross resistance problem, be used to prevent and treat sucking pest such as aphid, aleyrodid etc., it usually adds surfactant in use, but the adding of surfactant generally can not played synergistic effect to insecticide.
Polyoxyethylene nonylphenol ether is the surfactant of a class routine, a large amount of be applied in washing, daily use chemicals, aspects such as printing ink, its amphipathic property is relevant with polyoxyethylated number, in general, number is big more, hydrophily is strong more, a kind of emulsifier of agricultural sprinkling oil is disclosed for CN200510101977.3 as Chinese patent application number, the percentage by weight proportioning of its component is: polyoxyethylene nonylphenol ether 20～80%, and fatty alcohol-polyoxyethylene ether 20～80%, the polyethylene glycol dioleic acid ester is or/and polyethylene glycol monooleate 0～20%, butanols or certain herbaceous plants with big flowers alcohol 0～1%, polyoxyethylene nonylphenol ether is wherein used as a kind of basic emulsifier of conventional pesticide, can use as emulsifier in the agricultural chemicals in a lot, but itself does not have tangible insecticidal synergistic effect to most pesticide species.
Summary of the invention
The objective of the invention is to solve the effect that surfactant in the prior art can not synergy in the agricultural chemicals preparation, provide a kind of and can prepare the Imidacloprid preparation that synergistic effect is arranged surfactant and Imidacloprid insecticide.
Another object of the present invention provides the application of a kind of polyoxyethylene nonylphenol ether in this Imidacloprid preparation.
For solving the problems of the technologies described above, the invention provides a kind of Imidacloprid preparation, described preparation comprises surfactant and Imidacloprid, the proportioning of this surfactant and Imidacloprid counts 1 by weight: 10-10: 1.
Described surfactant is a polyoxyethylene nonylphenol ether, and its chemical structural formula is:
In the formula: n=4-15, EO represent oxirane (ethylene oxide).
The proportioning of described surfactant and Imidacloprid counts 1 by weight: 4-4: 1.
Described surfactant can be that one or more surface-actives in the said structure formula combine.
Also include suspending agent, micro emulsion, water and milk, missible oil, wetting powder, aqua, soluble liquid in the described insecticide.
The content of described Imidacloprid and surfactant accumulative total is counted 0.5-99 by weight.
The present invention also provides a kind of polyoxyethylene nonylphenol ether as the application of surfactant in the Imidacloprid preparation.
The present invention compared with prior art, the beneficial effect that is brought is: by using polyoxyethylene nonylphenol ether as surfactant in the Imidacloprid preparation, by suitable proportioning Imidacloprid is had good synergistic effect.
Further specify effect of the present invention below in conjunction with embodiment:
Embodiment
Embodiment 1
In order to study the synergistic effect of polyoxyethylene nonylphenol ether surfactant to agricultural chemicals, we have carried out mutual composite synergy research with Imidacloprid, and concrete grammar is:
With the control cotton aphid is example, the polyoxyethylene nonylphenol ether kind is right-n-nonyl phenol-polyoxyethylene (4) ether, be that n is 4 in the structural formula, producer provides former medicine, be mixed with the preparation that needs by my research department of company, the examination worm is the cotton aphid nymph of picking up from the field, the indoor feeding three generations, select growth even to two age nymph, insert to put cotton leaf (assorted No. 10 of Hunan, outer blade) culture dish that diameter is 9 centimetres, every ware connects 30, and every processing connects three wares, sprays under 50PSI pressure with the POTT spray tower, ware of each spray, 3 milliliters of every ware spraying liquids.General each processing is provided with 6-7 concentration gradient.The culture dish of handling is put into 25 ℃, cultivates in the 12H/12H illumination box, checks the survival borer population in 48 hours, calculates the insect population rate that goes down.The contrast surface activating agent is a Tween 80, blank spray equivalent clear water, calculate virulence equation and lethal concentration of 50 LC50 with method of least squares, calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC value) according to the abundant method of Sun Yun, the CTC value greater than 100 for synergistic effect, equaling 100 and be addition, is antagonism less than 100.Each medicament adding Nonyl pheno (4) ether different disposal the results are shown in Table 1 to the toxicity test of cotton aphid:

Table 3
Find out that from the result of table 3 Nonyl pheno (15) ether has good synergistic effect to Imidacloprid control thrips, co-toxicity coefficient reaches 142.4-686.6 in the ratio of test, and fast penetrant T does not have synergistic effect.Use Nonyl pheno (15) ether invalid separately to thrips.
The former medicine of conventional pesticide generally will add emulsifier etc. and could use as preparation, surfactant of the present invention is used for emulsification agricultural chemicals base oil, base oil is fully disperseed, adjustable being fitted in all mineral oil as the agricultural chemicals base oil also can directly be formulated in the mixed agricultural chemicals that above-mentioned mineral oil and other agricultural chemicals mix.
