Riža planthoppers include BPH, Nilaparvata planthopper and Nilaparvata planthopper. The three types of rice planthoppers have the same symptoms, and both adults and nymphs can harm rice. They all use their Piercing-sisa usta to pierce the stems, leaves, and uši of riža i absorb the juice from the the rice plants. Because the plant nutrients are konzumirano, it direktno afekti the growth of the biljka biljka. From the outside, the lišće turn žuto i smeđe, the growth is inhibirano, the plants are prone to Lodging, the heading and Plodonosno Are Are Pogođeno, And The Yield Is Significant Reducirano.
Danas I will introduce to you a compound that can učinkovito control various rice planthoppers-Triflumezopyrim. It is a new mezogenic pyrimidinone insecticide razvijen by Corteva. It is a a a nikotinic acetilkolin receptor inhibitor and can učinkovito control Lepidopteran and Homoptera štetočine. It can učinkovito prevent and control pests such as rice planthoppers and prevent viral diseases transited by rice planthoppers. It has now become a new benchmark za riža planthopper kontrola.
The mehanizam of action and application of Triflumezopyrim
Triflumezopirim djeluje on the nikotin acetilkolin receptor (nAChR) od insekata, but unlike most other insekticides that act on this receptor, it inhibits than activates it, making it a a nikotinic acetilkolin receptor inhibitor. After insect trovanje, the person bes trom and motionless without excitement or spazm, and then bes paralizirano, paralizirano, paralizirano, i na kraju dies.
The International Insecticide Resistance Action Committee (IRAC) classifies triflumezopyrim as Group 4E, a mesionic pesticide, which currently has only one active ingredient. Triflumezopyrim has has no cross-resistance with other insecticides within the group (uključujući neonikotinoid insekticide) or outside the group. Stoga, triflumezopirim can not only učinkovito control rice planthoppers, but is also an important tool for comprehensive management or resistance management of rice planthoppers, setting a new benchmark for rice planthopper prevention and control. Indoor biological results show that brown planthopper populations from Vietnam, Tajland, India and other countries are resistant to imidacloprid, but these resistant populations have no cross-resistance to triflumezopyrim. Even if rice planthopper populations develop metabolic resistance to a variety of insekticidi, uključujući neonikotinoidi, triflumezopyrim can still provide good and dugotrajna kontrola.
Triflumezopyrim is uglavnom korišten on riža, but can also be used on crops tak as pamuk, kukuruz i soja. Triflumezopyrim has good systemic vodljivost i propusnost, and otporan to kišnica erozija. It can be used for foliar prskanje, sjeme preljeva, cijepljenje, tlo liječenje. Field trials have confirmed that can can can control various rice planthoppers (uključujući smeđe planthopper, gray planthopper, bijela podloga Planthopper, itd.) , leafhoppers, etc., with good quick-act effect and long-longing effect. In addition, triflumezopyrim can promote rice growth and has a a good effect on imimproveing quality and ingrow yield.
Triflumezopyrim can be mixed with a variety of active ingredients. It includes not only tetrazoantraniliprole, chlorantraniliprole, cyantraniliprole, mebamektin benzoat, beflufenodiamide, metoksifenodiamid, metoksifenozid, fenmetrin, fentrile, Insekticidi tak as avermektin can also be kombinirani with the fungicides izotiastrobin, tricyclazole, etc., and can be used in nursery boxes, seed treatment, etc.

Sažeti
Riža je an important food crop, and rice planthoppers are one of the most serious pests in rice production. They are explosive, covert and destruktivne, and an important factor restriktivne high and stable rice yields. Due to long-and large-scale use of pesticides, rice planthoppers have developed variying degrees of resistance to konvencional pesticidi tak as pimetrozine, tiametoksam, tiametoksam, i nitenpyram.
As the first commercialized mezogen pyrimidinone pesticide, triflumezopyrim has set a new benchmark for the control of rice planthoppers due to its novel mechanism of action, good control effect, and low dosage. Triflumezopyrim can effective prevent and control rice planthoppers and sorte are are otporne to konvencional insekticidi. It can also prevent a variety of virus diseases caused by rice planthoppers and is appropriateable for resistance management and comprehensive pest control.
At present, triflumezopyrim is still within the patent protection period. As triflumezopyrim is registered in more countries and regions, and more compound products and single-dose products are promoted and applied, its market size will continue to expand.
