Bangsheng's "Invincible Shi" Brings the Gospel to Zhejiang Farmers
On June 23, 2018, our company held a launch conference of "Shi Wudi" in Haiyan, Zhejiang. We invited leaders of the local agricultural authority, experts in plant protection industry, and friends from dealers to share "Shi Wudi" in Zhejiang against resistance two. The results of the experimental demonstration of chemical pupae prevention and treatment analyzed the characteristics of the use of the agent and formed expert opinions, which laid a good foundation for the promotion of "Shi Wudi" in the Zhejiang market.
At the beginning of the meeting, Professor Gao Congfen of Nanjing Agricultural University introduced the resistance of rice cockroaches to different pesticides in various provinces and cities including Zhejiang in detail, and they basically showed an upward trend. Among them, the resistance to chlorantraniliprole dipyridamum has been increasing year by year since 2014. By 2017, the drug resistance multiples in most areas of Zhejiang have reached 180-400 times, and the control effect has decreased significantly. At present, areas with high to very high levels of resistance to chlorantraniliprole dipyridamide are mainly in southern and central Zhejiang, Poyang Lake and Nancheng in Jiangxi, and Hengyang in southern Hunan.
Later, Professor Gao introduced the technical points of Shi Wudi (10% Avicinyl-Beerazine SC), so that we can understand why the control effect of "Shi Wudi" is very unusual.
In the second item of the meeting, Mr. Kong Weibao, the general manager of the company, introduced the past, present and future development direction of our company to the leaders, experts and dealers, and emphasized our responsibility and responsibility; Strict quality control to ensure compliance with relevant standards; emphasized our persistent efforts to transform cutting-edge scientific and technological achievements into high-end technological products.
The third item of the meeting, the Director of Zhejiang Plant Protection and Quarantine Bureau Shi De introduced the occurrence of rice bollworm in 2018 so far. The main manifestations are as follows: 1. Large amount of insects. According to a survey by the Provincial Plant Protection and Quarantine Bureau in mid-March of single-season and double-season mixed planting areas, the amount of post-winter residual insects was similar to that of last year, with an average of 25,000 heads per mu, of which some fields in Yongkang and Xiangshan exceeded 100,000 head. 2. Moth peaks appear early. 3. The harm situation is unbalanced, and the harm in the coastal single and double season mixed cropping area is more serious. Comprehensive measures such as continuous planting of early rice, overwintering plowing irrigation, water killing, and sexual attractant traps were put in place. The harm of early rice first generation pupae was effectively controlled, and the comprehensive measures of overwintering were not put in place, especially for early rice fields planted with flowers. The second generation of puppets was severely harmed. Fourth, resistance develops quickly.
Later Shi Bureau also showed us the prevention and treatment of P. chinensis in different regions and different generations, and it was shown that 10% carbolic beetle hydrazine SC had a better control effect on P. chinensis, and it was effective for younger, The effect of first hatching larvae is good. In areas with high levels of resistance to avermectin, the performance is more prominent. Dosage: 50 ml / mu, application time: peak egg period.
In the fourth session of the meeting, senior expert Mr. Dong Taohai personally inspected and introduced the specific situation of the demonstration test of 10% carbamazepine SC in Shaoxing.
Shi Wudi (10% carbamazepine SC) was administered in a timely manner from the peak of egg hatching to the 1st instar larvae in the middle of pupae, showing a good control effect, a long-lasting effect, and effective control of The harm of pupae to rice was good in protecting seedlings.
The overall control effect is better than that of the common formula Kangkuan + Avermectin; it is suitable as one of the current alternative agents for the treatment of resistant pupae, and it is demonstrated and promoted in production.
In application technology, 50 ml per acre can be used as a recommended dosage to guide farmers' application. Silicone auxiliaries should be added when applying pesticides to ensure control effect.
At the meeting, Professor Shen Jinliang, Director Chen Zailiu, and Zhu Xiaoqun, etc. also introduced the occurrence status of rice cockroach and its control measures in detail, as well as the demonstration effect and product performance characteristics of the 10% carbamazepine test. Leading experts and friends from the distributors conducted in-depth analysis and discussions, formed expert opinions, and opened a new chapter for the application of "Shi Wudi" in the control of rice resistant diploid pupae in Zhejiang.
