Seed-soaking spraying agent and seed-soaking spraying method for controlling rot of peanut

Abstract

The invention belongs to the technical field of crop disease control, and relates to a seed-soaking spraying agent and a seed-soaking spraying method for controlling rot of peanut by using organic rare earth. The seed-soaking spraying agent comprises: in parts by weight, 20-40 parts of organic rare earth, 3-5 parts of EDTA, 1-3 parts of ammonium molybdate, and 0.5-1.5 parts of manganese sulfate. The method comprises: using a seed-soaking spraying agent diluent to soak seeds successively for three times, and spraying the finally-used diluent on the seeds for two stages. The method not only helps to retain yield-increasing effect of the rare earth microelement fertilizer, but also helps to develop antimycotic invasion antibacterial function of rare earth stayed in roots, and helps to prevent peanut from subjecting to harm of rot diseases (black shell, empty shell); and the diluents spraying plays a role of foliar topdressing, and helps to improve fruiting rate, increase chlorophyll content better and guarantee yield increase. Also, the seed-soaking spraying agent belongs to microelement fertilizers, and has the advantages of being free in pesticide, toxicity, odor, ''three wastes (waste gas, waste water and industrial residue)'' and pollution, and is a real green environment-friendly product.

Description

technical field [0001] The invention relates to a seed soaking and spraying agent and a seed soaking and spraying method for preventing and controlling peanut rot with organic rare earth. Background technique [0002] There are as many as seven kinds of diseases that cause peanut black shells and empty shells (that is, rotten fruit), involving 10 kinds of fungi, and it is difficult for a single pesticide to have broad-spectrum resistance to 10 kinds of fungi. The patent certificate of "Rare Earth Anti-Panut Black Shell Disease and Empty Shell Disease Seed Dressing Agent" was authorized and announced on March 13, 2013, with the patent number ZL201010172117·X. Mixed rare earth nitrate contains 16 kinds of rare earth elements such as lanthanum, cerium, praseodymium and neodymium, each of which has its own antibacterial spectrum. The combination of 16 kinds of rare earth elements naturally has a wider antibacterial spectrum, and the rare earth has a characteristic: 97% of the r...

Problems solved by technology

[0006] 3. Rare earth nitrate is acidic. In order to maintain acidity when diluted with water, organic acid and chelating agent should be added according to the difference in water quality during preparation. Therefore, the seed dressing agent is relatively acidic, and the dosage is limited. Too much is not good. emergence

[0007] This limitation affects the realization of the desired effect

[0008] 4. Rare earth nitric acid is easy to deliquesce. Facts have proved that a little water can also enter a layer of plastic bag and deliquesce. If the packaging is not strict, the bag stored in summer will absorb water and become porridge, which will affect the weighing accuracy.
