Abstract

In the prodn. of taxicless agricultural chemical mixture we use urea, synthesized washing powder or ammonium bicarbonate additive, potassium dihydrogen phosphate and thiourea etc. as main raw materialls. It features quick-acting, toxicless, no-residue, capable of absorbing by the plant leaves to serve as fertilizer and preventing multi-kinds of plant diseases and insect pests. The killing rate is 98.7% for cotton aphid and 92.6% for wheat midge. The rate for wheat prodn. increase is 5-17%.

Description

The compound method of urea and detergent compound mixture and production

Water invention belongs to a kind of compound method of efficient, nontoxic, the agricultural pact of noresidue.More particularly relating to a kind of is primary raw material with chemical fertilizer, not only can make fertilizer but also can make the compound method of the quick-acting non-poisonous pesticides of insecticide.

As everyone knows, past, China's agricultural chemicals commonly used has " 1605 ", " 1059 ", " 3911 ", " chlorophos ", " Rogor " or the like, though these agricultural chemicals have played positive effect to the control of the damage by disease and insect of China's agricultural in history, but they belong to highly toxic pesticide, and people and animals are had great toxic action, and the residual rate height executes that for a long time insect is developed immunity to drugs.So these agricultural chemicals not only use all very dangerously from producing to, and all exist the serious environmental pollution problem from producing to use.

At present, China's pesticide producing also just develops towards the direction of hypotoxicity, low-residual.As dimehypo, galecron, decis, dichlorvos, dicofol, enemy worm chrysanthemum fat, Belmark etc., all be good insecticide, for the agricultural foison of China is made very great contribution.But the production technology of these agricultural chemicals is more complicated also, and cost is higher, increased agriculture input, and, though these agricultural chemicals are not hypertoxic types, but also have very big toxicity to some extent, can cause grain and environmental pollution equally, also require further improvement.

Consider from the viewpoint of the ecological agriculture, develop the effect of a kind of existing high effect nontoxic disease-prevention and insecticide, but the agricultural chemicals of double as fertilizer again is for modern agriculture, imperative.

The object of the present invention is to provide a kind of compound method of agricultural chemicals urea and detergent compound mixture and production of efficient, nontoxic, noresidue, this kind urea and detergent compound mixture and production is used to kill cotton aphid, cotton bollworm, two spotted spider mite, acarid, and wheat midge, mythimna separata, wheat head aphid etc. have very high efficient; Head blight, hoja blanca for the control crops have good effect; Also be a kind of efficient mosquitocide simultaneously.The best proportioning of this kind urea and detergent compound mixture and production reaches 98.7% to the killing rate of cotton aphid; Killing rate to wheat midge reaches 92.6%; The time of tagging to mosquito is 3～5 seconds.Can make wheat (area, the Huaibei) volume increase 5～17%.This kind urea and detergent compound mixture and production raw material is easy to get, and cheap, preparing process is simple, does not need any plant equipment or reaction vessel.

The objective of the invention is to be achieved through the following technical solutions.

A kind of urea and detergent compound mixture and production is with urea, synthetic detergent powder or ammonium bicarbonate additive, potassium dihydrogen phosphate, thiocarbamide is the raw material preparation, and its weight proportion is: urea: synthetic detergent powder or ammonium bicarbonate additive: potassium dihydrogen phosphate: thiocarbamide=4: 1: 0.5: 0.01.By urea, synthetic detergent powder or ammonium bicarbonate additive, potassium dihydrogen phosphate, thiocarbamide is this kind urea and detergent compound mixture and production of raw material preparation, can make pulvis or solution (emulsion).

The present invention has following characteristics.

1, efficient, nontoxic, noresidue to the person poultry harmless, can not cause environmental pollution;

2, can kill various pests such as cotton aphid, wheat midge;

3, head blight, the hoja blanca to crops has better action;

4, be applicable to cotton, wheat, melon and fruit, vegetables etc.;

5, fine for indoor effect exterminating mosquito, effect rapidly;

6, production technology is simple, and cost is low, and is safe and convenient to use, has great social benefit;

7, the production-increasing function that has double as fertilizer.

Technical characterictic of the present invention is:

1, the K in this prescription ⁺Na ⁺Ion plays the K in the regulated value thing metabolic process ⁺-Na ⁺Balance, the ability of enhancing crop disease-resistant insect pest;

2, urea, potassium dihydrogen phosphate have the Foliage Absorption effect as foliage fertilization, promote plant growth;

3, surfactant has the dissolving of the insect of making cortex, the effect of body swelling fracture;

4, eliminate the pesticide resistance of insect to medicine.

By the spray solution that embodiment prepared of the compound method of a kind of urea and detergent compound mixture and production provided by the present invention, general crops spray by every mu of 75～100kg dosage.

By the following examples the present invention is further described.

Embodiment 1 (powder-type)

The compound method that a kind of urea and detergent compound closes is to be raw material with urea, synthetic detergent powder or ammonium bicarbonate additive, potassium dihydrogen phosphate, thiocarbamide, and its weight ratio is pressed urea: synthetic detergent powder: biphosphate: thiocarbamide=4: 1: 0.5: 0.01, make pulvis.When crops are sprayed, add water by water with weight ratio: urea: synthetic detergent powder: wink acid dihydride potassium: thiocarbamide=400～600: 4: 1: 0.5: 0.01, medicine powder: water=5.51: 400～600, that is the concentration of spraying after the dilution is 0.92～1.38%, generally sprays by 1%.

Embodiment 2 (emulsion-type)

A kind of compound method of urea and detergent compound mixture and production is made pulvis by embodiment 1.Then by weight, become medicine powder: water=make emulsion at 5.51: 4.49 during use, becomes 2% medicine liquid spray with the emulsion thin up.In this example, synthetic detergent powder replaces best with ammonium bicarbonate additive.

Claims

1, a kind of compound method of urea and detergent compound mixture and production is characterized in that this method comprises the steps:

A, should fill a prescription in urea, synthetic detergent powder, potassium dihydrogen phosphate, thiocarbamide by weight with 4: 1: 0.5: 0.01 mixes, and makes pulvis;

B, with the mix preparation of step a and water by weight making aqua with 5.51: 4.49 ratio;

C, pulvis that step a is made or the aqua thin up that step b is made become 1% solution to use.
