Best Pest Control
Best Pest Control – It is a compliant garments manufacturer with its own setup as well as own knitting and dyeing section in the same premises. Here the final product is a fabric garment, which continues from fabric, cutting, quality and finishing. Raw materials used in this factory is fabrics and in finishing and packing, various accessories like cartoon, poly, papers etc. 40% Emamectin Benzoate • thiamethoxam WG rice pest control experiment showed that 40% of the Emamectin Benzoate • thiamethoxam WG Mixtures and planthoppers on rice leaf roller control slow with quick result, the persistence of long, less medication, and good control effect …
After application 10d, insecticidal effect on the rice leaf roller 99.3% to 100%, 70.3% insecticidal effect planthoppers ~ 76.7%; after application 16d, the control effect of rice leaf roller shell of 99.2% volume ~ 99.5%, 70.9% insecticidal effect on planthoppers ~ 80.5%, in particular, the insecticidal control of rice leaf roller is better than a local harm used fungicides. .
In recent years the water for the rice leaf roller, and highlight trends in rice planthoppers retransmission, increasing difficulty in controlling the actual situation of victims, to promote the efficiency of controlling pests for pesticide reduction project implementation, the author introduced in 2008, 40% benzene, chlorine insects formamide • thiamethoxam WG mixture, the rice leaf roller on the vertical and planthoppers were the control effects of different dosage test. The results now reported as follows.
Materials and methods
for fungicides : 40% Emamectin Benzoate • thiamethoxam WG, Syngenta (China) Investment Co., Ltd. production; 5% fipronil SC, Bayer CropScience (China) Co., Ltd. production.
Experimental Design : Test 5 treatments were: 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2 (A), 120g/hm2 (B), 150g/hm2 (C), 5% fipronil SC 750mL/hm2 (D), the insecticide is not applied as control (CK). 3 repeats, district randomly arranged, each cell area of 64.8m2. In addition to pharmaceutical treatment factors, consistent with other management measures.
Test methods : Select Insert in the mechanical test on the kinds of rice varieties for the Ka 253 (mid-maturing varieties), when spraying began to break early rice growing period; application time for the third (1) on behalf of the vertical leaf roller peak times 2 Age 1 larval stage (June 19 afternoon), the amount of spray liquid at 450 kg/hm2. Weather conditions after application in Table 1. After the drug 3d, 10d, 16d, respectively, leaf roller and planthoppers residual worm investigation, calculation control effect.
Results and Analysis
An important aspect of pest control is denial of access to pests and maintenance of an environment, which discourages the development of infestation. Control and prevention of pest infestations in a workplace and environment requires a nessecity. Therefore, we have a contact with a reknown pest control company. They take Preventive measures to keep the pest population below injury level so that infestation cannot be developed in the stored products. They work as a continuous
The effect of control leaf roller : Control leaf roller results in Table 2. It can be seen after the drug 3d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments compared with the CK area, insects were reduced 87.0%, 93.7%, 80.7%, control volume bud results were 68.4%, 73.5%, 68.4%, 3 no significant difference between the treatments and the control of pharmaceutical Fipronil 5% SC 750mL/hm2 treatment compared to control volume bud similar effect, insects reduced slightly slower rate. After the drug 10d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments compared with the CK area, insects were reduced 99.3%, 100 %, 100%, control volume bud results were 98.2%, 98.4%, 99.2%, 3 still no significant difference between treatments, pest control volume reduction rate and shell effects are slightly better than 5% of the control of pharmaceutical suspension fipronil Agent 750mL/hm2 processing. After the drug 16d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments, the average leaf were 0.13%, 0.09%, 0.09%, control shell volume effects were 99.2%, 99.5%, 99.5%, slightly better than 5% of the control of pharmaceutical SC 750mL/hm2 fipronil treated control volume bud effect. Examine the situation from the 3, 40% Emamectin Benzoate • Prevention leaffolder thiamethoxam larvae generally quick result, but the effect of holding a long,
The effect of control planthoppers : Control planthoppers effect in Table 3. It can be seen after the drug 3d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments, control effect correction were 8.6%, 30.8%, 58.2 %, of which 120 g/hm2 and 150g/hm2 2 treatments is better than 5% of the control effect of fipronil SC 750mL/hm2 processing, 90g/hm2 slightly worse than control effect of fipronil SC 750mL/hm2 treatment. After the drug 10d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments, correction control effects were 70.3%, 71.4%, 76.7%, of which 150g / hm2 control effect is better than 5% fipronil SC 750mL/hm2 processing, 90g/hm2, 120g/hm2 control effect and 5% fipronil SC 750mL/hm2 handle basic similar. After the drug 16d, 40% Emamectin Benzoate • thiamethoxam WG 90g/hm2, 120g/hm2, 150g/hm2 3 treatments, correction control effects were 70.9%, 79.3%, 80.5%, of which 120g / hm2 and 150g/hm2 2 treatments is better than 5% of the control effect of fipronil SC 750mL/hm2 processing, 90g/hm2 control effect a little worse than 5% fipronil SC 750mL/hm2 treatment. Control effect from 3 test results, 40% Emamectin Benzoate • thiamethoxam WG on planthopper quick result is poor, but with time, the control efficiency increased significantly, also showed a longer support effectiveness; finally 120g/hm2 to deal with the basic control effect 150g/hm2 similar and better than 90g/hm2 control effect.
Summary and discussion
The results showed that: 40% Emamectin Benzoate • thiamethoxam WG planthopper control leaf roller and a little slow with the quick result, the characteristics of long persistence, especially for rice leaffolder borer has outstanding insecticidal control efficiency. 4d after administration of the test appeared to move into vertical leaf roller moth peak case, 10d and 16d after the drug test, test area after the peak has not yet appeared shell larvae and the rise in volume, indicating that the agent is a vertical volume control rice Ideally, a new leaf moth control chemicals can be used as the application of the current control leaf roller pesticide application in production. 40% Emamectin Benzoate • thiamethoxam WG longitudinal leaf roller, such as a single control, control time in addition to prevention and treatment in the 2nd instar larvae, but also can be controlled by the peak longitudinal leaf roller to 1 adult larvae for appropriate prevention and control of partial early; the recommended dose (the amount of goods) can be mastered in the 90 ~ 120g/hm2; as to simultaneously control leaf roller and planthoppers, the recommended dose (the amount of goods) to the hands of 120 ~ 150 g / hm2 appropriate.
Since 2008, more than the amount of rice planthoppers occurrence, and the white-backed planthopper planthopper and mainly the same time, the trial planthopper pest control area also show a certain amount of natural decline rate. Therefore, 40% Emamectin Benzoate • thiamethoxam WG Mixtures whether rice brown planthopper control with similar or better results, there will continue to explore. Beside this, we have yellow lights in all floors to prevent pest or insects. There are also insect killer machines in packing areas.
