13492-26-7 - Effect of potassium phosphite on the blight of Pinus tabulaeformis
from VIP
Author:
Liu Manguang , Lu Wenya , Li Guosong
Abstract:
The Inhibition effects of potassium phosphite on the mycelial growth and spore germination of Pinus tabulaeformis blight pathogen sphaerosis sapinea were determined by mycelial growth rate method and concave glass method, control effect of potassium phosphite compound on Pinus tabulaeformis and its physiological effect on Pinus tabulaeformis tree. The results showed that the inhibitory effect of potassium phosphite on the hyphal growth and spore germination of Pinus tabulaeformis increased with the increase of the concentration, and the inhibitory concentration (EC50) on the hyphal growth at 3 days was 7.360,24 h on the spore germination of EC50 was 19.058; Control of Chinese pine blight after injection of potassium phosphite compound agent, the experimental group trunk unit capacitance is higher than the control group, and potassium (K), phosphorus (P) the activity of superoxide dismutase (SOD) and polyphenol oxidase (PPO) were higher than those in the control group.

13492-26-7 - Introduction
potassium phosphite is an environmentally friendly, reusable and drug-resistant new multi-purpose special phosphorus and potassium fertilizer. Potassium phosphite is not only a phosphorus and potassium fertilizer of trivalent phosphorus, but also a systemic fungicide, and repeated use will not produce resistance. It is both a fungicide and a high potassium foliar fertilizer.
Disease prevention and bacteriostasis: rich in biological stimulator phosphite (containing trivalent phosphite phosphorus) can stimulate crops to produce polyphenols and reactive oxygen species (ROS), stimulate the activity of the defense enzyme system, and treat common diseases Fungal and viral diseases such as downy mildew, root rot, late blight, etc. have good preventive and therapeutic effects. Frequent use, crop disease resistance and stress resistance are greatly improved. Safe and efficient: It can be transported in two directions through xylem and phloem, with improved nutrient absorption rate, high efficiency utilization rate, pure nutrients, no hormones, no impurities, no blockage of nozzles and drip irrigation capillaries, and safer for roots, leaves, flowers and fruits. Loosen the soil, increase permeability, improve the rhizosphere environment, which is conducive to the health and strong growth of crops; promote the root and strong plants to promote the growth of flowers and fruits: the use of this product can promote the robustness of the plant, effectively control the top advantage, and avoid the vegetative growth of the plant. The crop flower buds are full, the flowers are strong, and the fruit setting rate and quality are significantly improved to increase production and income. It can be widely used in economic crops and field crops such as fruit trees, vegetables, melons and fruits, Chinese medicinal materials, seedlings and flowers in the north and south.
most of the time, it actually acts as a biological stimulant. it may not directly act on germs, but it can stimulate crops to form their own defense system, which is equivalent to animal vaccines. Moreover, potassium phosphite has the effect of internal absorption and up-and-down conduction. It can be transported in both directions in the xylem and phloem of the plant. The absorption speed is faster than that of phosphate phosphorus, which activates crops to produce polyphenols and active oxygen molecules, and stimulates defense The enzyme activity has the effect of eradicating, treating and preventing diseases in the crop. Regular use can greatly improve the resistance and disease resistance of the crop, improve, it has good effects on promoting roots, flowers and fruits.
