Benefits of technology

This patented technology improves upon existing methods by combining different chemicals together with other substances that improve their effectiveness over time. It also reduces harmful side-effects associated with these treatments while still being effective at controlling various diseased plants such as vegetables, fruits, flowers, nuts, seeds, grains, etc., which can be damaging to human health if consumed without proper treatment. Additionally, this method helps prevent pests from entering agricultural lands through leaks into waterways during raining periods due to heavy use of fertilisers containing sulfur compounds. Overall, this new approach provides an efficient way to control plant disease outbreaks effectively and safely.

Problems solved by technology

This patented technical solution describes how combination chemistry between five chemical substances called pentaerythaimidazolidone, trimetaphosphene, 2-(2'-dimethyno-2', 4 '-trimethenyltriphenyllithium), dichromane, trisporphyrin, pyranesulfonic acid, ironixacrolide, zinc oxysalenirnae, etc., improves their ability to fight various types of germinary plant pathogens such as grey miterries, root rot caused by phytosphasis on crops like rice plants without causing any harmful effects upon them.

Embodiment 1～17

[0041] Embodiment 1~17 wettable powder

[0042] Mix penthiopyrad, active ingredient B, dispersant, wetting agent, and filler in a mixing tank, pulverize them with a jet mill, and then mix them evenly to obtain the wettable powder product of the present invention. For details, see Table 1. Table 1 Embodiment 1~17 each component and parts by weight

[0043]

[0044]

Embodiment 18～34

[0045] Embodiment 18~34 water dispersible granules

[0046] Penthiopyrad, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are air-pulverized together to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

[0049]

[0050] New preparations can be obtained by exchanging cymoxanil, dimethomorph, propamocarb or its salts, valevecarb, captan, chlorothalonil, metalaxyl or their salts in Tables 1 to 2.

Embodiment 35～51

[0051] Embodiment 35~51 suspending agent

[0052] Dispersant, wetting agent, defoamer, thickener (optional), antifreeze agent (optional), after high-speed shearing, mix evenly, add penthiopyrad and active ingredient B, and grind in a ball mill Medium ball milling for 2 to 3 hours, so that the particle size is all below 5 μm, and the balance is supplemented with deionized water, and the suspension product of the present invention can be obtained. See Table 3 for details.

Abstract

The invention discloses a bactericidal composition containing penthiopyrad, which contains an active component A and an active component B, wherein the active component A is selected from penthiopyrad; the active component B is selected from any one of cymoxanil, dimethomorph, propamocarb or salt thereof, iprovalicarb, vondcaptan, chlorothalonil, and metalaxyl or salt thereof; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a synergistic action on multiple diseases jeopardizing agricultural production, reduces the pesticide consumption, lowers the residue level of the pesticide on crops, relieves the environmental pollution, is safe for both human and livestock and has favorable environmental compatibility, and the diseases can not easily generate drug resistance.
