Abstract
The present invention relates to a kind of mosquito children agent for killing, specifically, the present invention relates to a kind of sustained release agent that is applied to the kill mosquito children of water body.Slow-releasing agent for killing larvel mosquito provided by the invention comprises as the fatty acid of carrier and surfactant and insecticide.After this slow-releasing agent for killing larvel mosquito drops into water body, the slow self-dissolving of fatty acid is emitted wherein contained insecticide gradually, because the effect of surfactant makes insecticide be distributed in water surface, the children plays the most effective killing action to mosquito, the blowing agent that sustained release agent contains makes it float on water meter, guarantees that insecticide only distributes at the movable water meter of mosquito children.The advantage of this slow-releasing agent for killing larvel mosquito is economical and efficient.
Description
The present invention relates to a kind of mosquito children agent for killing, specifically, the present invention relates to a kind of sustained release agent that is applied to the kill mosquito children of water body.
In existing technology, the river has grown in the water bodys such as pool after the mosquito children, generally is directly to be applied to water body with agricultural chemicals to reach the purpose killed.With the shortcoming of the method is that the amount of application of agricultural chemicals is big, and the agricultural chemicals major part of being used slatterns, and pollutes easily, its former because:
1, insecticide can not all reach target organism-mosquito children after using, and most of agricultural chemicals does not have effect.For example, have the mosquito children movable all around in the wide 2 meters zone in one 100 square metres pools, the agricultural chemicals of using can not have mosquito children zone at this.
2, after insecticide is used,, insecticide is decomposed, thereby must constantly increase dose to recover damage owing to expose to the weather and natural various effects such as microorganism, keep drug effect.
3, the part that insecticide is not decomposed, meeting is run off with water, has both caused waste, increases again and pollutes.
The purpose of this invention is to provide a kind of slow-releasing agent for killing larvel mosquito that is applied to water body, in the hope of reaching the purpose of utilizing insecticide rationally, efficiently.
The objective of the invention is to realize by following mode.
The slow-releasing agent for killing larvel mosquito that is applied to water body provided by the invention is characterized by, and this slow-releasing agent for killing larvel mosquito comprises as the fatty acid of carrier and surfactant and insecticide.Described carrier fatty acid is C
12Above long-chain fatty acid.The ratio of fatty acid is to account for 20～40% of slow-releasing agent for killing larvel mosquito gross weight.The hydrophilic and oleophilic ratio of described surfactant (HLB value) is greater than 8.The preferential nonionic surface active agent that adopts.The ratio of described surfactant is to account for 5～10% of slow-releasing agent for killing larvel mosquito gross weight.The preferential polyoxyethylene nonylphenol ether that adopts in the described nonionic surface active agent.The ratio of the insecticide in the described slow-releasing agent for killing larvel mosquito is to account for 5～15% of slow-releasing agent for killing larvel mosquito gross weight.Described insecticide can be organic phosphor type insecticide, comprise Swebate, phoxim, dichlorvos, quinalphos, fenthion, malathion, it can be organochlorine type insecticide, comprise benzethazet acetofenate 7504, can be that carbamate comprises Bassa, unden, can be that pyrethroid comprises decis, cypermethrin, sumicidin.Slow-releasing agent for killing larvel mosquito from the above mentioned also comprises blowing agent in its composition.Described blowing agent can be made of sodium bicarbonate and weak acid, and described weak acid comprises citric acid, oxalic acid.The sodium bicarbonate of described blowing agent and the part by weight of weak acid are approximately 0.5～1: 1～2.Described blowing agent accounts for 5～10% of slow-releasing agent for killing larvel mosquito gross weight.
In described slow-releasing agent for killing larvel mosquito, can also comprise bactericide, such as kitazine or iprobenfos.
Can also comprise synergist in described slow-releasing agent for killing larvel mosquito, described synergist can be piperonyl butoxide, Octachlorodipropyl Ether.
The invention has the advantages that, since as the fatty acid of carrier in water body slow dissolving and the insecticide that will wherein contain is emitted rallentando, thereby make the dispenser water body have the very long insecticide survival time, can be because of the mobile rapid decline that causes insecticide concentration of water.And eliminate fully owing to carrier meeting self-dissolving, so can not cause any residual contamination.Because the effect of the surfactant in this sustained release agent, insecticide is only distributed in water surface, and very low in water body internal insecticides concentration, utilization of pesticides quantity is reduced, simultaneously, play the most effectively killing action for mosquito children in the water surface activity.Prove with this slow-releasing agent for killing larvel mosquito according to the contrast experiment and to save insecticide 1/3, not only reduced use cost but also reduced harm environment than the kill mosquito of spray medicine.
In addition, make sustained release agent density reduce the blowing agent that floats owing to also containing in the composition of slow-releasing agent for killing larvel mosquito provided by the invention, so, make this sustained release agent float on water surface all the time, guarantee effect is played in the water meter distribution of insecticide.
Below the present invention is further illustrated by specific embodiment, and protection scope of the present invention is not done any qualification.
Embodiment:
Adopting the soap stock of Soap Factory is the main source of sodium soap, and its chain length is C after measured
12～C
18Contain the 20%(weight ratio) sodium soap, consumption accounts for 70% of slow-releasing agent for killing larvel mosquito gross weight.Add high carbon acid or stearic acid or tallow fatty acid and account for 10% of slow-releasing agent for killing larvel mosquito gross weight as adding the fatty acid consumption.Use polyoxyethylene nonylphenol ether to be surfactant, its consumption accounts for 8% of slow-releasing agent for killing larvel mosquito gross weight; Insecticide adopts quinalphos, and its consumption accounts for 10% of sustained release agent gross weight; Adopt sodium bicarbonate and citric acid to constitute blowing agent, the weight of blowing agent accounts for 5% of gross weight, and wherein the weight ratio of sodium bicarbonate and citric acid is about 1: 1.2.
The observation of on-the-spot killing mosquito larvae efficacy:
Select 9 environment such as sewage, clear water, half sewage, circulating water, water capacity is respectively at 0.3～5M
3About, every square metre of water surface is thrown one piece of above-mentioned sustained release agent 20 gram, and investigation mosquito children density is fetched water 5 spoonfuls with 500ml aluminium spoon at random in all directions, looks it and has or not mosquito children and counting to try to achieve averag density, observes once, and drops into the mosquito children in good time in per 5 days.The mosquito children who drops into has white palpus yellow-fever mosquito, three bands and Culex pipiens pallens and disturbs the mosquito children who draws Ah mosquito, observed 30 days, except that 7, No. 8 sewage pools after 20 days accidental disturbing draw the Ah mosquito mosquito children, it is movable that other environment there is no the mosquito children, drop into the mosquito children again after each the observation, its survival is not seen in inferior daily inspection yet.
