Problems solved by technology

[0005] Both dimehypo and hexaconazole are low-toxicity pesticides. When used alone, dimehypo and hexaconazole have their own advantages and disadvantages. For example, dimehypo has good quick-acting effect, but poor persistence

Embodiment 1

[0015] Example 1: Indoor toxicity test of the mixture of dimehypo and hexaconazole to rice leaf roller.

[0016] The indoor bioassay method is as follows: the capillary micro-drop method is adopted, and the volume of the capillary micro-dropper is 1.0 μL. Use a micro-dropper to drip the medicinal solution head by head on the back of the 3rd instar larvae of the rice leaf roller, and treat about 30 larvae at each concentration, and put every 5 larvae into a petri dish with a diameter of 9 cm, and a small amount of feed inside the dish For feeding, another 30 larvae were dripped with acetone as a control. The treated larvae were still placed in the breeding room, and the mortality rate was checked after 48 hours. The data were statistically processed by SPSS software, and the co-toxicity coefficient was calculated by Sun Yunpei's method.

[0017] The joint toxicity of the mixed preparation is expressed by Sun Yunpei's co-toxicity coefficient method:

[0018] The measured toxi...

Embodiment 2

[0026] Example 2: Indoor virulence test of the mixture of dimehypo and hexaconazole against rice sheath blight.

[0027] The calculation method is:

[0028] Toxicity index TI (B) = EC of standard agent A 50 / EC of agent B 50 *100

[0029] Measured Toxicity Index (ATI) = (standard drug EC 50 / Test agent EC 50 )*100

[0030] Theoretical toxicity index (TTI) = Toxicity index of agent A * percentage of A in the mixture + toxicity index of B agent * percentage of B in the mixture

[0031] Co-toxicity coefficient (CTC) = [mixture measured toxicity index (ATI) / mixture theoretical toxicity index (TTI)] * 100

[0032] Evaluation criteria are: co-toxicity coefficient ≥ 120, showing synergistic effect; co-toxicity coefficient ≤ 80, showing antagonism; 80<co-toxicity coefficient < 120, showing additive effect.

Embodiment 3

[0040] Embodiment 3: 12% dimehypo-hexaconazole wettable powder

[0041] Dimehypo: 11 parts;

[0042] Hexaconazole: 1 part;

[0043] Pull open powder; 3 parts;

[0044] Sodium lignosulfonate: 1 part;

[0045] Filler - Kaolin: make up to 100 parts.

[0046] Spray the measured dimehypo liquid on the measured kaolin to make it fully absorbed, stir evenly, then add the fungicide hexaconazole and pesticide adjuvant, and process the dosage form according to the conventional processing method of pesticide wettable powder. 1 kg of 12% dimehypoxaconazole wettable powder was obtained.

[0047]

[0048]

[0049] The above active ingredients dimehypo, hexaconazole and various pesticide adjuvants were processed according to the conventional processing method of pesticide water emulsion to obtain 1 kg of 25% dimehypo·hexaconazole emulsion in water.

Abstract

The invention discloses pesticidal bactericide containing bisultap and hexaconazole; the pesticidal bactericide contains active ingredients: bisultap and hexaconazole, having a weight ratio of 60:1 to 1:60. The pesticidal bactericide as a mixture is in the form of suspension, emulsion in water, wettable powder, water-dispersible granule and the like. The pesticidal bactericide can treat Cnaphalocrocis medinalis, Thanatephorus cucumeris, other rice diseases, and pest damage, can treat pest and disease damages by single application, fewer applications are required, the cost of applying bactericides to control crop harmful organisms can be effectively reduced, farmers feel less difficult to select pesticides, and the pesticidal bactericide is beneficial to organisms and environment and can protect the good ecological environment of farmlands.

Description

technical field [0001] The invention belongs to the field of rice pest control. Specifically relates to a high-efficiency insecticide and fungicide containing dimehypo and hexaconazole. Background technique [0002] The rice leaf roller is the most serious pest during the rice growth period. Rice leaf roller [Cnaphalocrocis medinalis (Guenee)] is a migratory pest that occurs in various rice areas in my country. production cuts. Rice sheath blight has always been an important disease during the rice growth period, causing serious losses all year round. [0003] Bisultap, a nereistoxin biomimetic insecticide, is a nerve agent. Dimehypo has strong contact and stomach poisoning effects on pests, and also has a certain fumigation effect. It can be absorbed and conducted by the leaves, stems, roots, etc. of crops. After pests eat plants containing dimehypo, they will show slow response, slow action, and lose the ability to infringe crops, which will cause pests to stop develop...
