Regarding the control range of chlorantraniliprole, DuPont PPT said this:
Chlorfenapyr has high efficiency and broad spectrum, and has good control effect on LEPIDOPTERA, such as Noctuidae, Mothidae, Mothidae, Mothidae, Lepidoptera, Coleoptera, Lepidoptera, etc. Diptera Muscidae; Bemisia tabaci and other non-Lepidoptera pests.
According to the preliminary test, the effect on LEPIDOPTERA pests is really good, and the control time is very long, but the effect on Bemisia tabaci, flea beetle and ape leaf worm is very uncertain. I hope that those who have used chlorantraniliprole will talk about their experience after using it.

brief introduction
edit
Pesticide residues in agricultural products and their toxicity to animals have always been the focus of attention. In recent years, DuPont has successfully developed a variety of pesticides with high efficiency and low toxicity, which are changing the impact of pesticides on the environment. World pesticide research-successfully developed chlorantraniliprole, trademark: Kangkuan. Generic name: 200g/L (20%) chlorobenzamide suspension. The application technology of this innovative pesticide is introduced as follows:
Product characteristics
edit
1. This product has obtained all certificates of pesticide registration and sales application, and can be widely used. Because the chemical structure of chlorantraniliprole has a brand-new insecticidal principle that no other insecticide has, it can effectively activate insect (muscle) receptors. Excessive release of calcium ions from intracellular calcium pools leads to paralysis and death of insects, which has high activity, wide insecticidal spectrum and good persistence to Lepidoptera insect larvae. According to the current test results, the activity against target pests is 10- 100 times higher than other products, and it can lead to the disorder of mating process of some LEPIDOPTERA insects. Studies have proved that it can reduce the oviposition rate of many Noctuidae pests. Because of its biological characteristics of good durability and rain erosion resistance, these characteristics are actually the comprehensive embodiment of permeability, conductivity, chemical stability, high insecticidal activity and making pests stop eating immediately. Therefore, it is determined that it has a more lasting and stable protection effect on crops than most other pesticides currently used.
2. At present, the dosage form and content are registered in the Prevention and Control of Main Pests in Rice, which can quickly protect the growth of rice, especially for other rice pests that have developed drug resistance, such as rice leaf roller, Chilo suppressalis, Chilo suppressalis and Chilo suppressalis, and also have good control effect on rice gall midge, rice weevil and rice water weevil.
3. The pesticide belongs to micro-toxic level, which is very safe for pesticide users and beneficial insects, fish and shrimp in rice fields. The persistent period can reach more than 15 days, which has no residual effect on agricultural products and good mixing performance with other pesticides.
applied technology
edit
1. According to the application of Zhejiang Plant Protection Department to control rice leaf roller, use 10 ml per mu, spray two barrels with backpack manual sprayer for routine spraying. After seven days, the insecticidal effect reached 94.2% and the leaf protection effect reached 90.0%. After fourteen days, the insecticidal effect reached 86.0% and the leaf protection effect reached 83.9%. Both of them are superior to the commonly used 5% fipronil 40ml/ mu in control effect.
2. According to the application of Sichuan provincial drug inspection department in the control experiment of Chilo suppressalis, 10 ml was used per mu, and two barrels were sprayed with backpack manual sprayer, and conventional spraying was used. After 20 days, the control effect of white spike reached 96. 1%, and the control effect of pest plants reached 98.7%. The insecticidal effect reached 93.6%. The comprehensive control effect is better than the commonly used 5% fipronil 40ml/ mu and 20% triazophos 140 ml.
Comprehensive experiments and demonstrations all over the country show that: 1. In the experiment in Anhui, 5 ml of this pesticide was poured into a bucket with 4 liters of water, and then live goldfish were put in. A few hours later, the goldfish is still swimming, which shows that it is very toxic to fish and can prove that it is safe for aquatic animals. 2. Experiments and demonstrations in Hubei, Jiangsu, Shanghai and other places to control rice leaf roller, Chilo suppressalis and Chilo suppressalis all show that its control effect is better than that of conventional domestic and imported pesticides, and it has great application potential in the control of recurrent pests in rice producing areas in China.
Application and popularization
edit
1. Because of its strong permeability, pesticides can pass through the epidermal cell layer of the stem and enter the xylem, so that they can be conducted along the xylem to other parts that have not been applied. Therefore, when working in the field, it is better to spray or fine spray. However, when the temperature is high and the evaporation in the field is large, the medicine should be used before 10 in the morning and after 4: 00 in the afternoon, which can not only reduce the dosage of liquid medicine, but also better increase the amount and permeability of liquid medicine accepted by crops, which is conducive to improving the control effect.
2, in order to avoid drug resistance, a crop or a pest should be used for 2-3 times, each time the interval is greater than 15 days.
3. The pesticide has different dosage forms, contents and applicable crops when registered in China. Users should choose different pesticide contents and dosage forms according to different crops.
In addition, DuPont Agrochemical Company organized a pesticide-"Puzun" on-site exchange meeting in Fengxian District, a cooperative network for testing, demonstrating and popularizing new vegetable pesticides in Shanghai. The common name of Puzun is 5% chlorantraniliprole suspension concentrate, which is a new pesticide developed by DuPont Company in the United States. Slightly toxic, the control object is Lepidoptera pests. Insects stop feeding 7 minutes after application, the validity period is more than 10 day, and the safety interval is 1-3 days. The product is resistant to rain erosion, and it will rain 2 hours after spraying, so it is not necessary to spray again.
Dupont explained the insecticidal mechanism, product characteristics and application effect of the product in detail, and Fengxian, Songjiang and Jinshan who participated in the experiment also exchanged information. Plant protection leaders from all districts and counties visited the experimental field of Qingcun Town, Fengxian District. Among all the chemical treatments of cabbage, "Puzun" showed outstanding post-control effect on Plutella xylostella. Everyone recognized the use effect of "Puzun", and at the same time exchanged and discussed issues of concern to everyone, such as product price and application technology. Yu, assistant director of Shanghai Agricultural Technology Center, believes that the effect of Puzun is worthy of recognition, whether from the intuitive performance of the test site or the reflection of the test data. In order to popularize new pesticides more strictly, we should be as cautious as possible in the test arrangement, be as realistic as possible in the test implementation process, and make an objective evaluation after the test. It is necessary to make full use of this platform, accelerate the substitution of new pesticides through the continuous introduction of new pesticides, do a good job in the safe use of pesticides, strengthen the training and guidance of new pesticides, and ensure the edible safety of vegetables.

Functional characteristics
edit
1 is an excellent, efficient and broad-spectrum insecticide against LEPIDOPTERA, main beetles and whitefly. Its control effect is reliable and stable at low dose, and it stops feeding immediately, and its efficacy is more lasting, preventing rain erosion and providing immediate and long-term protection at any period of crop growth. Its mechanism of action is different from other kinds of pesticides. It can bind to fish dinin receptor in insects, inhibit insects from feeding, make insects shrink, and eventually lead to pest death.
2. A new generation of pesticides with brand-new mechanism of action is the best pesticide for pest resistance control and crop rotation.
3. It has low toxicity to mammals and is very safe for pesticide users.
4, low toxicity to beneficial arthropods such as birds, fish and bees, and is very suitable for integrated pest management.
5. It is safe for consumers and reaches the maximum residue limit standard.
Main action pathway
–Stomach poison quickly stops eating (7 minutes), and soon loses vitality and vomits. Due to continuous decalcification, muscle paralysis significantly inhibited growth and died within 24~72 hours.

Control of rice leaf roller with chlorantraniliprole
Article source: Jiangsu Agricultural Science and Technology News
20% chlorantraniliprole suspension concentrate is a new generation of super-efficient pesticide developed by DuPont company in the United States. The drug has a brand-new mechanism of action, has a high control effect on LEPIDOPTERA pests such as Plutella xylostella, is not easy to generate cross-resistance with existing pesticides, has low toxicity to fish, bees, aquatic organisms, natural enemies and mammals, and is very friendly to the environment. In 2008, Jiangsu Plant Protection Station and other units carried out the experimental demonstration work of this drug to control rice leaf roller, and achieved good comprehensive application results.
Pharmacodynamic test
edit
The experiment includes two parts: plot experiment and field demonstration. The plot experiments were carried out in Zhangjiagang and Jiangyan, and each acre was treated with 20% chlorantraniliprole suspension 10 ml, 50 ml fipronil suspension, 40% chlorpyrifos EC 100 ml and blank control. Field demonstration was carried out in Zhangjiagang, Jiangyan and Liyang, and 20% chlorantraniliprole suspension concentrate 10 ml was used per mu. The control chemicals in Zhangjiagang are 5% fipronil suspension concentrate and 32% profenofos hexaflumuron EC, and the dosage per mu is 50 ml. The contrast agent of Jiangyan is 20% emamectin benzoate? The dosage of chlorpyrifos wettable powder and 16% fipronil chlorpyrifos EC per mu were100g and120ml respectively; The contrast agent in Liyang is 5% fipronil suspension concentrate, and the dosage per mu is 50 ml. All treatments were used at the peak of the fifth (third) generation of rice leaf roller, which was a peak larva.
The results of plot experiment showed that chlorantraniliprole showed high insecticidal and leaf protection effects after 3- 15 days, among which the insecticidal effect reached 79.2% after 3 days, which was higher than that of the control, especially after treatment (94.3-96.29%) and 10-6544 days. The field demonstration results showed that after 7- 15 days, the effect of killing insects and protecting leaves was over 92.4%, and the control effect was obviously better than that of fipronil single agent and its compound, 32% profenofos hexaflumuron EC and 20% emamectin benzoate chlorpyrifos WP.
The results showed that chlorantraniliprole had good quick-acting and persistent effect on rice leaf roller, and its insecticidal and leaf-protecting effects were better than those of the control. It is suggested that the pesticide should be applied from the peak of egg incubation to the peak of larvae, and 20% chlorantraniliprole suspension 10 ml should be used per mu. The drug is highly toxic to silkworm, so it should be used safely in the mixed cropping area of rice and mulberry.

Dupont has submitted its application for registration of its newly developed pesticide Rynaxypyr (chlorantraniliprole) to pesticide management agencies in several OECD countries. This application has also been submitted to the European Union (represented by Britain and Ireland), Australia, Canada and the United States. Mr. James collins, vice president and general manager of DuPont Crop Science Company, said: "This is an important step for us, because it can ensure that this variety will enter the commercialization road early next year." This pesticide will be sold all over the world under the trade names Altacor and Coragen and applied to agriculture.
Rynaxypyr is the 1 insecticide screened from anthranilic compounds. It has a unique mode of action and can provide a long-term and broad-spectrum control effect on chewing mouthparts pests that harm field crops, fruit trees, vegetables, other special crops and lawns. Dupont has transferred the global right to use Rynaxypyr in composite products to Syngenta.
In the past five years, more than 3500 field experiments and 400 management studies have fully confirmed the effectiveness of this variety in pest control and its extremely low toxicity to mammals, birds and fish. Dupont has applied to the United States and Canada for large-scale field experiments on special crops. They are likely to be realized this year. This variety is expected to be commercialized in 2008.
