Problems solved by technology

In recent years, plant virus diseases have become more and more harmful to fruits, vegetables, flowers and various economic crops. At present, plant virus control agents widely used in production, such as morpholine hydrochloride · copper acetate, succinic acid copper · hydrochloride Long-term use of guanidine, octoprodil · morpholine hydrochloride, etc. has caused plant viruses to produce strong resistance to it, and the dosage and cost are constantly increasing. For this reason, it is very important to develop a new type of plant virus control composition. urgent

Embodiment 1

[0015] Example 1: Indoor Toxicity Test and Formula Screening of Tobacco Mosaic Virus Disease Compounded by Morpholine Hydrochloride and Copper Quinoline

[0016] Test materials: Tobacco mosaic virus diseased leaves were collected from the field, and the virus filtrate was obtained by grinding and filtering in the laboratory and stored for later use.

[0017] Test method: The composition of the present invention (morpholine guanidine hydrochloride, quinoline copper) is tested for indoor synergism by conventional methods. Calculation of Inhibitory Medium Concentration EC by Least Squares Method 50 (95% confidence limit), and then calculate the co-toxicity coefficient (CTC) by Sun Yunpei's method.

[0018] Co-toxicity coefficient (CTC) ≥ 120 represents synergistic effect; co-toxicity coefficient (CTC) ≤ 80 represents antagonism; 80 < co-toxicity coefficient (CTC) < 120 represents additive effect.

[0019] .

[0020] Table 1 shows the indoor toxicity test results of differe...

Embodiment 2

[0025] Embodiment 2: 80% morpholine hydrochloride quinoline copper water dispersible granules.

[0026] Morpholine hydrochloride 56.5%, quinoline copper 23.5%, sodium lauryl sulfate (wetting agent) 5%, polycarboxylate (dispersant) 3%, sodium chloride (disintegrant) 2%, poly Ethylene glycol (binder) 3%, soluble starch (stabilizer) 3%, kaolin (carrier) to make up to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 80% morpholine hydrochloride quinoline copper water dispersible granules.

[0027] This embodiment is used for preventing and treating capsicum tobacco mosaic virus disease, and 80% morpholine hydrochloride quinoline copper water dispersible granule active ingredient consumption 210 grams / hectare is watered and sprayed, and the control effect is 88.6% in 10 days after the medicine; 80% Morpholine guanidine hydrochloride water dispersible granule active ingredient dosage 1200 g / ha mixed water spray, 10 days aft...

Embodiment 3

[0028] Embodiment 3: 40% morpholinidine hydrochloride quinoline copper suspension concentrate.

[0029] Morpholine hydrochloride 35%, copper quinoline 5%, sodium methylnaphthalene sulfonate formaldehyde condensate (wetting agent) 10%, Nongru 600# phosphate (dispersant) 3%, xanthan gum (thickener) ) 1%, ethylene glycol (antifreeze) 4%, soluble starch (stabilizer) 3%, deionized water to make up to 100%. Mix the above formula evenly in proportion, grind and high-shear to prepare 40% morpholine guanidine hydrochloride quinoline copper suspension concentrate.

[0030] This embodiment is used for preventing and treating potato Y virus disease, and 40% morpholine hydrochloride quinoline copper suspending agent active ingredient consumption 400 grams / hectare is watered and sprayed, and control effect is 89.1% in 10 days after the medicine; 80% morpholine hydrochloride The dosage of water dispersible granules is 1200 g / ha mixed with water and sprayed, and the control effect is 82.7% 1...

Abstract

The invention relates to a pesticide composition for preventing and treating plant virus diseases. The pesticide composition comprises two active components of moroxydine hydrochloride and oxine-cooper, wherein a weight part ratio of the moroxydine hydrochloride to the oxine-cooper is 10:1-1:5. According to a combination of the two active components of the pesticide composition provided by the present invention, a synergistic effect is provided, control efficiency is improved, generation of the plant virus resistance is delayed, the use amount of the pesticide is reduced, such that cost is reduced and environmental pollution is decreased.

Description

technical field [0001] The pesticide composition involved in the invention uses morpholine hydrochloride and copper quinoline as active ingredients, and is suitable for preventing and controlling plant virus diseases in agriculture. Background technique [0002] Virus disease is a kind of important disease that harms crops. It is called plant cancer because of its serious harm and difficulty in prevention and control. In recent years, plant virus diseases have become more and more harmful to fruits, vegetables, flowers and various economic crops. At present, plant virus control agents widely used in production, such as morpholine hydrochloride · copper acetate, succinic acid copper · hydrochloride Long-term use of guanidine, octoprodil · morpholine hydrochloride, etc. has caused plant viruses to produce strong resistance to it, and the dosage and cost are constantly increasing. For this reason, it is very important to develop a new type of plant virus control composition. u...
