Abstract
The invention relates to a bifenthrin and malathion-containing pesticidal composition. The composition is mainly characterized in that: the pesticidal composition comprises 1 to 20 percent of bifenthrin, 2 to 29 percent or 31 to 49 percent of malathion, assistants and other excipients, and is prepared into microemulsion or emulsion in water. The pesticidal composition is used for preventing and controlling aphids, budworms, plant hoppers, cotton bollworms, diamond back moths and lesser green leaf hoppers on cash crops and vegetables.

The invention belongs to technical field of pesticide, be specifically related to the Pesticidal combination of a kind of malathion and Biphenthrin, be used to prevent and treat the insect on fruit tree, economic crops, the vegetables.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active height; (3) selectivity height.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Biphenthrin belongs to chrysanthemum ester insecticide, and the main mode of action is stomach toxicity and tags, suction in not having, fumigation action, and the control spectrum is wide, and the lasting period is longer, does not move in soil, and is safer to environment.Be used to prevent and treat cotton bollworm, two-spotted spider mite, peach fruit borer etc.
In recent years, along with the drug-fast increase of damage by disease and insect, peasant's dosage is synergy thereupon also, and vicious circle is also stepped in the agricultural chemicals use, pollution to environment is more and more heavier, environmental protection, efficient, lasting period length are an urgent demands to the proposition of pesticide producing factory, in order to satisfy the needs of agricultural production, make full use of two kinds of active components be mixed the synergistic effect that produces, improve preventive effect, suspension of pesticide resistance generation, the present invention proposes the Pesticidal combination that contains malathion and Biphenthrin of a kind of efficient, low toxicity, low-residual.
In the present technique field, the different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find malathion and Biphenthrin can produce good synergistic effect after composite, and quick-acting is preferably arranged, reduced the agricultural chemicals access times, suspension of pesticide resistance generation, the lasting period is long.Up to now, composite aqueous emulsion, the microemulsion product of malathion and Biphenthrin do not reported as yet.

Embodiment
Below in conjunction with embodiment to further instruction of the present invention.
Implementation of an application example one:
The Biphenthrin malathion is to tea lesser leafhopper toxicity test and prescription screening
The above embodiment of the present invention is designed 5 concentration respectively by active constituent content to be handled, the worm leaf dipping method is soaked in employing, aphid is immersed 5s in the soup together with tea leaf, take out the back and sop up unnecessary soup on the leaf margin with blotting paper, put it into the raising of preserving moisture in the culture dish of beating, put into 25 ℃ illumination box then, check the survival borer population after 48 hours, every concentration is handled and is repeated 3 times, the every repetition with 90 of examination worms.Calculate the insect population rate that goes down, proofread and correct the insect population rate that goes down, try to achieve virulence regression equation and calculate LC
50
The tea lesser leafhopper corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (with the Biphenthrin is the standard medicament, and its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=Biphenthrin of M
BiphenthrinTI * the P of+malathion
The malathion
In the formula: M is the mixture of different proportionings
P
BiphenthrinBe Biphenthrin shared ratio in composition
P
The malathionBe malathion shared ratio in composition
The different proportionings with the malathion of table 1 Biphenthrin are used the virulence to tea lesser leafhopper with
As shown in Table 1, the composite co-toxicity coefficient to tea lesser leafhopper in Biphenthrin and malathion all greater than 120, shows synergistic effect in 1: 49 to 10: 1 scope, the most obvious with some synergistic effect in 1: 1 to 1: 20.So research and extension of the present invention is significant.
