Problems solved by technology

At present, chemical pesticides are mainly used to control D. destructor with exogenous substances. In China, phoxim, dicarbicarb, carbofuran, thiazophos and other organophosphorus pesticides are mainly used for root irrigation or poisonous soil spraying to prevent nematodes. Most of the pesticides are highly toxic, the dosage is large, and the control is difficult. The long-term application of chemical pesticides is not conducive to the sustainable development of agricultural safety, environmental protection, and has become an urgent problem in agricultural production today.

Embodiment 1

[0059] Embodiment 1: compounded by following weight ratio:

[0060] A: Take 100 grams of betel nut and pumpkin seeds in total (areca nut: pumpkin seed weight ratio = 1:1); add 100 g of the Chinese herbal medicine material with the weight ratio, add appropriate amount of water, extract with boiling water for 30 minutes, and then dilute to 500ml;

[0061] B: 50 grams of Tween 80, 25 grams of sodium dodecylbenzenesulfonate;

[0062] C: The remainder is water.

[0063] Mix the above formulas evenly and set the volume to 4000ml for later use. It can be diluted 1 to 10 times. The effect of direct root irrigation on D. destructor is determined by the insect soaking method, and the killing effect is 55 to 90%. It can also be processed into water in any proportion and directly used for the control of nematodes.

Embodiment 2

[0064] Embodiment 2: compounded by following weight ratio:

[0065] A: Take 100g of betel nut and pumpkin seeds in total (areca nut: pumpkin seed weight ratio = 4:6); add 500ml of 70% ethanol to 100g of the said weight ratio Chinese herbal medicine material, extract it for 7 days, evaporate the ethanol for later use;

[0066] B: A total of 100g of cocklebur and flavescens (weight ratio of cocklebur: flavescens = 1:1); extract 100g of the Chinese herbal material with the weight ratio and 500ml of 70% ethanol for 7 days, evaporate the ethanol for later use;

[0067] C: 50 grams of Tween 80, 25 grams of sodium dodecylbenzenesulfonate;

[0068] D: remaining water.

[0069] Mix the above component formulas evenly and set the volume to 5000ml for later use; the above formulas can be diluted 1 to 10 times, and the effect of direct root irrigation on D. destructor is determined by the method of soaking insects, and the killing effect is 60 to 94%. It can also be processed into water...

Embodiment 3

[0070] Embodiment 3: compounded by following weight ratio:

[0071] The total amount of the formula is 2 kg.

[0072] A: Pumpkin seeds and betel nut dry powder total 1000g (pumpkin seeds: areca nut weight ratio = 2:1);

[0073] B: 1000g of fermented products of cocklebur, flavescens, licorice, pomegranate and pulsatilla in total (take one part for each of the five materials)

Abstract

The invention discloses a medical fertilizer for preventing and controlling nematodes and an application method. Betel nuts, pumpkin seeds, paris polyphylla, dahurian patrinia herb, cocklebur fruits, sophora flavescens, liquorice, pomegranate, Chinese pulsatilla roots, melia azedarach, rhizoma cibotii and other Chinese herbal medicine extracting solutions are used as a plant pesticide, compound pesticide prepared by the plant pesticide and a biological pesticide is used for preventing and controlling the nematodes, especially ditylenchus destructors harming various crops and is a low-toxicity, environment-friendly and green plant pesticide, the crop quality can be also improved, and crop yield can be improved. The medical fertilizer is a novel multifunctional ecological environment-friendly pesticide and has the active pushing effect on effective reduction of high-toxic pesticide application.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to medicinal fertilizers and application methods for preventing and treating plant pathogenic nematodes. Background technique [0002] D. destructor is a serious hazard at home and abroad, and it is one of the important diseases in sweet potato production areas. There are many kinds of hazards and serious economic losses. At present, chemical pesticides are mainly used to control D. destructor with exogenous substances. In China, phoxim, dicarbicarb, carbofuran, thiazophos and other organophosphorus pesticides are mainly used for root irrigation or poisonous soil spraying to prevent nematodes. Most of the pesticides are highly toxic, the dosage is large, and the control is difficult. The long-term application of chemical pesticides is not conducive to the sustainable development of agricultural safety, environmental protection, and has become an urgent problem in agricultural ...
