Abstract
The present invention relates to a kind of method preventing and treating citrus red mite, according to effective ingredient weight ratio 1-2:3-5:5-10, avilamycin, etoxazole and Cascade are carried out medicament mixture, is then watered dilution, even spraying is on Citrus leaf.The composition pesticide of the avilamycin of 3 kinds of different mechanism of action, etoxazole and Cascade rational mixture is used for preventing and treating citrus red mite by the present invention, there is obvious synergistic function, drug effect can be greatly improved, reduce pesticide mu consumption, thus reduce the harmful effect to environment and pesticide residues, extend the persistent period of drug effect, the shortcoming that single dose easily produces resistance can be overcome simultaneously.
Description
Technical field
The present invention relates to a kind of agricultural planting management technique field, a kind of method preventing and treating citrus red mite.
Background technology
Citrus red mite is because its fertility is very strong, life cycle is shorter, take place frequently, so easily producing acaricide anti-throughout the year
Property and make drug effect be decreased obviously, at present, preventing and treating citrus red mite all use chemical agent to prevent and treat, mainly there is also following difficulty
Point is waited to capture: the lasting period of medicament is short, though can reach preferable effect after dispenser, but usually breaks out again after three or five days；
Reagent toxicity is relatively big, and medicament residual is serious.
Summary of the invention
It is an object of the invention to, it is provided that one is efficiently, low toxicity, quick-acting are good and the lasting period is long, can effectively prevent and treat the red spider of Citrus
The method of spider.
The present invention solves above-mentioned technical problem and is adopted the technical scheme that: a kind of method preventing and treating citrus red mite, by Avermectin
Element, etoxazole and Cascade carry out medicament mixture according to effective ingredient weight ratio 1-2:3-5:5-10, are then watered dilution, uniformly spray
Mist is on Citrus leaf.
The weight ratio of described avilamycin, etoxazole and Cascade is preferably 1:4:7 or 1:3:6.
The invention have the advantages that and remarkable result had by the different avilamycin of mechanism of action, etoxazole and Cascade these 3
The composition pesticide of effect composition rational mixture is used for preventing and treating citrus red mite, has obvious synergistic function, can be greatly improved
Drug effect, reduces pesticide mu consumption, thus reduces the harmful effect to environment and pesticide residues, extend the persistent period of drug effect,
The shortcoming that single dose easily produces resistance can be overcome simultaneously.
Detailed description of the invention
Below with measure the indoor joint toxicity measuring test of biocidal activity and field medicine effect test to technical scheme and
Technique effect is described further, and percentage ratio of the present invention is all weight percentage.
Embodiment 1: avilamycin, etoxazole and Cascade and the different ratio toxicity test to panonychus citri
Test method is with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T1154.12-2006 ".Pick up from the full pawl of Citrus in field
Demodicid mite female one-tenth demodicid mite, through indoor feeding 30 generation, selects the female one-tenth demodicid mite of growth uniformity as examination worm.Use seedling method, i.e.
Little basin Citrus Seedling connects Panonychus citri 50-60 head demodicid mite, after 1 day, checks radix, after choosing except dead demodicid mite, mend to add and live into demodicid mite, retain
Often processing demodicid mite number is about 50.Use spray tower to spray the Seedling having demodicid mite, move into 25 DEG C, under the conditions of relative humidity 90%
Cultivate, check after 15 days, record survival number, carry out statistical analysis with DPS data processing software, calculate regression curve, obtain
LC50, use the abundant co-toxicity coefficient method (CTC) waiting nineteen sixty to propose of Sun Yun to evaluate the potentiation of pharmacy mix.Co-toxicity coefficient
Computing formula is as follows:
Actual measurement toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
In theoretical toxicity index (TTI)=A medicament ATI × mixture in the percentage composition+B medicament ATI × mixture of A the hundred of B
Divide content
Co-toxicity coefficient (CTC)=(mixture ATI/ mixture TTI) × 100
When CTC≤80, compositions shows as antagonism, and as 80 ＜ CTC ＜ 120, compositions shows as summation action,
When CTC >=120, compositions shows as potentiation.
Result of the test is shown in Table 1.
Table 1 avilamycin, etoxazole, Cascade and the different ratio toxicity test (15 days) to panonychus citri
From table 1, when the weight ratio of avilamycin, etoxazole and Cascade carries out mixture between 1-2:3-5:5-10, respectively
Individual proportioning co-toxicity coefficient has all reached more than 120, and compositions shows as obvious potentiation to the virulence of panonychus citri.Ah
The part by weight of dimension rhzomorph, etoxazole and Cascade is that 1:8:11 carries out mixture, and mixed ratio is not when 1-2:3-5:5-10, altogether
Poison coefficient is 106.5, only shows as summation action between mixture.
The compound method of embodiment 2:20% avilamycin etoxazole Cascade suspending agent and medicament field test
By recipe requirements, above component is pressed the amount mix homogeneously of formula, after sand mill grinds, obtain 20% avilamycin second
Demodicid mite azoles Cascade suspending agent.
This embodiment preparation is used for preventing and treating Citrus shatangju garden panonychus citri, and test period is in August, 2014, with conventional blade face spray
Mist is uniformly prevented and treated, and is as the criterion so that blade is moistening.During dispenser, field Panonychus citri becomes demodicid mite more.Test sets 4 process, each place altogether
Manage 4 repetitions.Field insect population radix is investigated before dispenser, 1 day, 7 days and 21 days respectively 1 insect pest situation of investigation after medicine, calculate preventing and treating effect
Really.
Result of the test is shown in Table 2.
The field control effectiveness test of table 2 20% avilamycin etoxazole Cascade suspending agent preventing and treating panonychus citri.
As shown in Table 2, after avilamycin, etoxazole and Cascade carry out rational mixture, complex preparation relatively single dose is used alone,
Improving a lot the prevention effect of panonychus citri, pesticide usage amount significantly reduces, and can effectively reduce the bad shadow to environment
Ring, improve the lasting period of medicament simultaneously, decrease spraying times, significantly reduce the labor intensity of agricultural operation.
The compound method of embodiment 3:8% avilamycin etoxazole Cascade microemulsion and medicament field test
Weigh 1.0% avilamycin, 3.0% etoxazole, 5.0% Cascade, 4%TX-10,5% Nongru-700 #, 6% agriculture breast 500#,
3% agriculture breast 1601#, 15% Ketohexamethylene, 5%N-methyl pyrrolidone, 5% n-butyl alcohol, 1% epoxychloropropane, through dissolving completely
And mix homogeneously, deionized water complements to 100% weight portion, prepares 8% avilamycin etoxazole fluorine worm after stirring
Urea microemulsion.
This embodiment preparation is shown in the harmful demodicid mite of citrus orchard for preventing and treating green grass or young crops, and test period is in June, 2014, field Panonychus citri during dispenser
Become demodicid mite more, use conventional foliar spray uniformly to prevent and treat, be as the criterion so that blade is moistening.Test sets 4 process, each place altogether
Manage 4 repetitions.Field insect population radix is investigated before dispenser, 1 day, 7 days and 21 days respectively 1 insect pest situation of investigation after medicine, calculate preventing and treating effect
Really.
Result of the test is shown in Table 3.
The field control effectiveness test of table 3 8% avilamycin etoxazole Cascade microemulsion preventing and treating Saccharum Sinensis Roxb. citrus red mite
From the result of the test of above field control effectiveness test embodiment it can be seen that the avilamycin etoxazole fluorine of the present invention
Worm urea composition pesticide is outstanding to citrus red mite prevention effect, compositions from quick-acting or the persistency of drug effect all than list
Agent has significant improvement.Meanwhile, process of the test Chinese medicine is safe to fruit tree, not affects natural enemy.
