Abstract
The invention relates to a nematode killing agent, whose characteristic components are as follows: 2-5 g of potassium chloride, 4-10 g of urea, 2-5 g of potassium dihydrogen phosphate, 8-20 g of starch, 2-10 ml of nemamort, 10-20 g of metham, 1000 ml of water and a little amount of ethanol. The invention is a nematode killing agent, which has the advantages of low residual quantity, low toxicity to mammal, security for non-target organisms in environment. The product not only can effectively control nematode, but also can improve stress resistance for plant, and provide nutrients for crops.
Description
Technical field
The present invention relates to a kind of agricultural chemicals, specifically a kind of nematicide agricultural chemicals.
Background technology
Plant nematode is one of plant infectious cause of disease, and they extensively colonize in root, stem, leaf, flower, bud and the kind reality of each kind of plant, make plant that various oxyuriasis occur.The current nematode harmful to plant, the kind more than 40 that has in China's discovery, mainly contain rhabditis axei, root knot nematode, cyst roundworm, pratylenchus etc., wherein crop is endangered to root knot nematode and cyst roundworm most serious of all, the crop mainly being endangered has cucumber, peanut, soybean, paddy rice, wheat, potato, straw etc.The general generation of nematode just can make this class crop failure 10%-40%, energy underproduction 70%-80% when serious, and even total crop failure, its hazard rating has some idea of.
Nematode is a kind of lower animal, individual tiny, but nematode polypide inside has flourishing Digestive tract and reproductive system, in plant materials, draw its needed nutrition, neural system, other animals of Excretory system geometric ratio want simple many, generally will under powerful microscope, just can see these internal structures clearly.Plant nematode has very large hazardness, except drawing host's nutrition and plant tissue being caused physical abuse, the esophageal gland of Plant nematode also can be secreted toxic substance, these materials contain multiple digestive ferment, bring out host tissue various pathological changes occur, Ke Shi plant tissue cell hypergenesis, form megabacterium, or making cellular layer dissolving cause that cell decomposes, cell walls is destroyed, causes root and top layer to form cavity and necrocytosis.
Summary of the invention
The object of this invention is to provide a kind of residual quantity low, to Mammals low toxicity, nematocides to the non-target organism safety in environment.
Nematocides of the present invention, is characterized in that composition is: Repone K 2～5g, urea 4～10g, potassium primary phosphate 2～5g, starch 8～20g, dichloroisopropyl ether 2～10ml, metamsodium 10～20g, and water 1000ml, ethanol is a small amount of.
Nematocides of the present invention, its preparation method is:
(1) first dichloroisopropyl ether, metamsodium are first dissolved in a small amount of ethanol;
(2) take respectively Repone K, urea, potassium primary phosphate, starch, soluble in water;
(3) (1), (2) are mixed, be surely dissolved in the graduated cylinder of 1000ml, bottling.
Nematocides of the present invention, dilutes 200～400 times by stoste during use.
Nematocides of the present invention can not only effectively be prevented and treated nematode, and can improve the resistance of plant, supplies with the required nutrient of crop, uses safety.
Embodiment
Embodiment
Nematocides of the present invention, its preparation method is:
(1) first by dichloroisopropyl ether 3ml, metamsodium 10g, be first dissolved in a small amount of ethanol;
(2) take respectively Repone K 2g, urea 50g, potassium primary phosphate 3g, starch 10g, soluble in water;
(3) (1), (2) are mixed, be surely dissolved in the graduated cylinder of 1000ml and bottle.
The present invention obtained above is carried out to 200 times of dilutions, with clear water, process in contrast.Each processing arranges 3 repetitions, respectively by 7 days, 14 days and 28 days inoculation nematodes, observes 24 hours survival nematode numbers.Result demonstration, is used prevention effect of the present invention good, and mortality ratio is high.
