Abstract
The present invention a kind ofly is the synergism compound preparation of main active ingredient with fenpropathrin and phoxim (or flolimat).Be mainly used in control cotton, vegetables, insect pest of the fruit tree, it has efficiently, the characteristics of wide spectrum, mite class and lepidopterous larvae etc. are had special efficacy, and being specially adapted to has drug-fast area to chrysanthemum ester or organic squama, and this complex preparation is cheap, it only is 30～50% of fenpropathrin, because its insecticidal spectrum is wide, can reduce spraying times again, the saving of labor, save time, help reducing agriculture use cost, increase economic efficiency.
Description
The invention belongs to the pesticide processing formulation, a kind of complex preparation that is applicable to control cotton, vegetables, insect pest of the fruit tree of saying so in more detail.
Phoxim (or flolimat) is one of organophosphorus insecticides kind, it once with efficient, insecticidal spectrum is wide and welcome, but in recent years along with the growth of service time, particularly because single variety uses continuously repeatedly and consumption is improper, cause insect pest that its resistance is constantly increased, drug effect descends, and dosage obviously improves, and agriculture use cost increases.Fenpropathrin is one of pyrethroid pesticide kind, put the initial stage on market at it, promptly with efficient, low toxicity, dosage is few and account for rapidly in agricultural chemicals market, so that the gesture that superseded organophosphorous pesticide is arranged greatly, but growth along with the operating period, exposed its not good to mite class preventive effect and the insect pest resistance increases sharply weakness very soon, even some original situation of selling well districts becomes the resistance district, lost use value.In order to delay the generation of insect to certain class pesticide resistance, increase the service life, keep drug effect, it is very necessary carrying out dissimilar agriculture chemical compounding research.Though achievement in research is a lot of aspect pesticidal preparations both at home and abroad, multiple complex preparation supply the market is also arranged, up to the present, Shang Weiyou is the agriculture chemical compounding formulation of main active ingredient with fenpropathrin and phoxim (or flolimat).
The objective of the invention is for the resistance that solves aforementioned fenpropathrin and organophosphorous pesticide, improve insecticidal effect, reduce use cost and the complex preparation of a kind of fenpropathrin and organophosphorus insecticide is provided.
Compounded preparation of pesticide of the present invention is that to be with organophosphorous pesticides such as fenpropathrin and phoxim or flolimats that main active ingredient is carried out composite, and it is formulated to add suitable emulsifier, solvent, cosolvent etc., and its formula range is:
Active ingredient (fenpropathrin and organic phosphor total amount) 20～30%
Emulsifier 5～15%
Solvent and cosolvent 55～75%
Active ingredient in the above-mentioned prescription can be fenpropathrin and phoxim, also can be fenpropathrin and flolimat, its ratio each other should be taken all factors into consideration the regional insect pest resistance situation of control, factor such as synergistic effect and use cost is determined, the relative scale of general fenpropathrin and organic phosphor (phoxim or flolimat) should be controlled at 1: the scope of (3～5), laboratory test and field application result show, its best enhancing proportions scope is: 1: (3.5～4.5), through Toxicity Determination, in this scope, its co-toxicity coefficient can reach 140～210.
Selected emulsifier is the mixed emulsifier of nonionic and anionic in this complex preparation, can select commercial goods RQ-3 for use, RQ-10, RQ-11, use wherein a kind of or their mixture, generally be HLB value, to obtain the optimum emulsification effect according to concrete consumption and the ratio and the solvent situation adjusting selection emulsifier of active ingredient.
Employed solvent can be selected benzene,toluene,xylene or their mixture etc. for use in this complex preparation, and employed cosolvent is the low-molecular-weight fat alcohols, as methyl alcohol, ethanol, butanols etc.
The processing process of this complex preparation is seen accompanying drawing 1.
This complex preparation is an emulsion, and outward appearance is light brown, as clear as crystal single-phase even oily liquids, and stability meets GB1603-79 agricultural-chemical emulsion stability criterion.
When using this complex preparation, generally need thin up 2000-4000 doubly, carry out the field spray dispenser, its lasting period is 7～15 days.
This complex preparation is mainly used in crop pests such as cotton, vegetables, fruit tree, control as cotton bollworm, aphid, tortrix moth, cabbage caterpillar, two spotted spider mite, peach fruit borer etc., particularly more obvious in the regional result of use that fenpropathrin or phoxim, flolimat etc. are developed immunity to drugs, its insecticidal effect generally all is higher than independent use fenpropathrin, miticidal effect is particularly outstanding.Its control efficiency sees following each table for details:
