Description
Technical field
The present invention relates to cultural control technical field, the granular pesticide of specifically a kind of prevention sugarcane moth borer.
Background technology
Sugarcane is the major economic crops in Guangxi, and sugarcane borer, sugarcane tortoise are two kinds of primary pests in Guangxi sugarcane producing region, wherein sugarcane
Snout moth's larva is especially prominent to the harm of sugarcane.Sugarcane borer is all harmful in sugarcane entire growth period, and seedling stage growing point of causing harm causes withered heart seedling,
Withered heart rate is generally 10%~20%, serious up to 50% or more, and middle and later periods brill moth causes harm sugarcane stem, destroys sugarcane stem tissue, hinders
Sugarcane production causes windbreak, reduces yield and sugar.From 31 days October in 2013, since terbufos are forbidden producing and make
With rear, sugarcane insect pest especially sugarcane moth borer becomes to be on the rise.Therefore, it is badly in need of having a kind of high-efficiency low-toxicity insecticide, can has
The harm of the control sugarcane moth borer of effect.
Fluorobenzene insect amide, English name：Flubendiamide belongs to novel phthalic amide insecticides, activates blue Buddhist nun
Calcium release channel in alkali recipient cell leads to the runaway release for storing calcium ion, is few in number at present to act on insect
The compound of cell orchid Buddhist nun's alkali receptor, has spectrum preventive effect to lepidoptera pest, with existing insecticide no interactions resistance generate, at
Worm preventive effect is limited, without ovicidal action, is slightly passed to by xylem after infiltration plant is interior, resistance of rainwater washing against.
Phoxim, English name：Phoxim is a kind of organophosphorus insecticide, with tag with stomach toxicity based on, no interior suction is made
With insecticidal spectrum is wide, knocks down that power is strong, also has good action effect to the larva of a variety of lepidoptera pests.Phoxim applies in soil, residual
It stays the phase very long, is suitable for preventingSubterranean pest-insect。
Inventors discovered through research that by fluorobenzene insect amide and phoxim with certain weight ratio mixture, composition is to sweet
Sugarcane borer worm synergy is apparent, can reduce the dosage of each single dose, mitigates drug cost.Currently, being made with fluorobenzene insect amide and phoxim
For active ingredient composition be applied to sugarcane moth borer study on prevention there are no relevant reports.
Invention content
The object of the present invention is to provide a kind of granular pesticides of prevention sugarcane moth borer, have high-efficiency low-toxicity, can be significantly
The advantages of improving drug effect, reducing Pesticide use amount, reduce pesticide mu input cost.
The technical solution used in the present invention is:A kind of granular pesticide of prevention sugarcane moth borer, active ingredient is by fluorobenzene
The weight ratio of insect amide and phoxim composition, fluorobenzene insect amide and phoxim is 1:1-10, it is preferred that fluorobenzene insect amide and pungent sulphur
The weight ratio of phosphorus is 1:5 or 1:8.
Weight percent of the fluorobenzene insect amide in granular pesticide is 0.2-2.0%, and phoxim is in pesticide
Weight percent in granula is 0.4-5.0%.
The adjuvant that the granular pesticide is added includes filler, binder, dispersant, wetting agent, disintegrant, stabilization
Agent or other active ingredients that are beneficial to stablize the substance played with drug effect in the formulation, are all common or fair in field of pesticide preparation
Perhaps the various composition used.
The present invention has the following advantages and significant technique effect:
(1) with the composition of fluorobenzene insect amide and phoxim rational proportion, prevention sugarcane moth borer has synergistic effect, not only
The plurality of advantages of original each single dose is kept, but also makes each component usage amount reduction in the case where activity is not lost in mixture,
Increased to the activity of mixture.
(2) by fluorobenzene insect amide and phoxim compound, pest is made to be difficult to eliminate mode of action different insecticides simultaneously to it
Influence, delay in pest population drug resistance individual to generate.
(3) present invention is prepared into granular pesticide, in conjunction with the plantation of new sugarcane or the big ridging application of sugarcane, alleviates farming behaviour
Make, more saves labor.
Specific implementation mode
Technical scheme of the present invention and technique effect are described further below by way of specific embodiment, institute of the present invention
The percentage stated is weight percentage.
One, indoor joint toxicity measuring test
Embodiment 1：The indoor joint toxicity measuring of fluorobenzene insect amide, phoxim and its mixture to sugarcane moth borer

Quasi- NY/T1154.7-2006》, experiment is with fluorobenzene insect amide, phoxim single dose medicament as a contrast, containing fluorobenzene insect amide, pungent
Comparison medicament, measurement medicament are respectively set by active constituent content at 6 gradient concentrations as medicament is measured for the mixture of sulphur phosphorus
Reason, using the processing without medicament as blank control (CK).
2, test method：Using 10s dip methods, the extra liquid of test worm is drawn with filter paper, test worm is put into insect box later
Middle raising each handles 3 repetitions, and it is 40 each to repeat test worm number used, and 72h checks dead borer population after medicine, calculates dead
Rate and corrected mortality, it is for statistical analysis with DPS data softwares, virulence regression equation (y=a+ is acquired with least square method
Bx), the LC of each medicament and is thus calculated50Value.
According to the co-toxicity coefficient method (CTC) of (1960) SunJohnson come evaluate active insecticidal components fluorobenzene insect amide,
Whether phoxim is mixed has synergistic effect, co-toxicity coefficient (CTC) is calculated, when co-toxicity coefficient (CTC) >=120 table of compounding agent
It is now synergistic effect；CTC≤80 show as antagonism；80<CTC<120 show as summation action.On this basis, it then carries out
Field control effectiveness test.
Statistical result is as shown in table 1.
Table 1：The Toxicity Determination of fluorobenzene insect amide, phoxim and its mixture to sugarcane moth borer (chilo infuscatellus)
As known from Table 1, fluorobenzene insect amide, phoxim show obviously sugarcane moth borer within the scope of specific weight ratio
Synergistic effect, wherein weight ratio be 1:5 or 1:Synergy is most notable when 8, there is good reference value in field control effectiveness test.

(3) test result
Result investigation is carried out after sugarcane moth borer on June 28th, 2014, investigate per the total seedling number of cell and sugarcane
Snout moth's larva, which is caused harm, causes withered heart seedling number, calculates withered heart rate and control effect.
(4) calculation formula：Withered heart rate=withered heart seedling number/total seedling number * 100%.Control effect=(check plot withered heart rate-it applies
Medicine area withered heart rate)/check plot withered heart rate * 100%.
(5) test result is shown in Table 2.
The field control effectiveness test statistical form of 2 fluorobenzene insect amide of table, phoxim and its mixed agent prevention sugarcane moth borer
Can be obtained from the test data table of table 2, test group 1#, test group 2# sugarcane withered heart rate be respectively 4.28% and
5.98%, hence it is evident that less than the withered heart rate of control group 1#, control group 2#, test group 1#, test group 2# also show sugarcane borer control effect
Higher than control group 1#, control group 2#, illustrate the rational mixture of fluorobenzene insect amide and phoxim, synergy is notable, can greatly improve pair
The control effect of sugarcane moth borer advantageously reduces the dosage of each single dose, reduces drug cost, can control the danger of sugarcane moth borer
Evil, there is good application value.
