Description

Chlopyrifos and phoxim compound granular insecticide

Technical field

The present invention relates to a kind of efficient pesticides that is used to prevent and treat soil insect, a kind of compound insecticidal granule that contains chlopyrifos and phoxim of more specifically saying so.

Background technology

Sugarcane moth borer, sugarcane tortoise are the main soil insect in the sugarcane production, deal with improperly and will cause sugarcane to drop in production over a large area and the quality reduction.Sugarcane is the primary raw material source that China produces sucrose, and its industry size is big, and the pesticide dosage that is used for the sugarcane controlling underground pest has considerable scale.In recent years, because the using repeatedly in a large number of some high-toxic pesticides, unitary agent, cause the part insect to produce resistance or resistance strengthens, some conventional pesticide preventive effects constantly descend, and must increase dosage and frequency of utilization improves preventive effect, the production cost increasing; Simultaneously, directly have influence on the foreign exchange earning of people's consumption health and even China's sugar industry because the use of a large amount of high-toxic pesticides will cause exceeding standard of persticide residue in the sugarcane.On the other hand; because the China environmental protection dynamics is strengthened day by day; restriction, the use of forbidding high-toxic pesticide have become inevitable, and this also will cause, and the control of insect preparation variety reduces in the sugarcane field, develop for this reason new efficient, low-residual sugarcane controlling underground pest preparation is very necessary and urgent.

Though China's sugarcane controlling underground pest preparation has kind more than ten at present, but many weak points have been remained, the for example use of some high poison, persistent pesticide nuvacron, carbofuran, thimet and complex preparation thereof etc. is because of it progressively is limited person poultry toxicity's height, residual quantity senior general or bans use of; Insecticide remains shortcomings such as having immediate effect property is poor, insecticide efficiency is low under a lot of sugarcane fields that use at present: some conventional agricultural chemicals list agent will cause the sugarcane insect to produce resistance because of its prolonged and repeated use or resistance strengthens; Some missible oil class pesticidal preparations because of its production will consume a large amount of organic solvents, cause its cost to raise, and unfavorable transportation, in use will cause bigger environmental pollution again, need careful for using.

Summary of the invention

The objective of the invention is to by science, advanced compounded preparation of pesticide technology, for the control of sugarcane soil insect provide a kind of efficient, quick-acting, low-residual, formulation advanced person, safe in utilization, what be difficult for producing resistance is that Main Ingredients and Appearance is by the composite granular insecticide that forms of certain technology path by chlopyrifos and phoxim.

The invention provides a kind of is the granule complex preparation that mainly contains effective constituent by chlopyrifos and phoxim, and its each component proportioning (percentage by weight) is as follows:

Chlopyrifos 1～20%

Phoxim 1～20%

Adsorbent 1～13%

Binding agent 0.5～11%

Stabilizing agent 0.2～15%

Synergist 0.1～8%

Colouring agent 0.2～1.5%

Carrier 96～40%

In the above-mentioned prescription, described chlopyrifos can be selected the former medicine of chlopyrifos or female powder for use, and phoxim is selected crude oil for use; Described adsorbent can be selected polo-neck soil, bentonite, diatomite, attapulgite, white carbon, potter's clay, atlapulgite, talcum powder, fine particle calcium carbonate for use; Described binding agent is selected a kind of or several mixing in polyvinyl alcohol, polyvinyl acetate, dextrin, starch, the gum Arabic for use; Described stabilizing agent is selected phosphorous acid or triphenyl phosphate for use; Described synergist is Butacide, synergy phosphorus, azone; Described colouring agent selects that brilliant violet, crystalviolet, product purple, the red B of polarity, phthalein green grass or young crops are red for use, the blue or green orchid of phthalein, phthalein viridescent.

Described carrier is selected river sand, ore, gangue for use.

A kind of method for preparing hot (chlopyrifos+phoxim) compound insecticidal granule of poison, carry out as follows:

1. the former medicine of effective ingredient chlopyrifos or female powder, phoxim crude and adsorbent are mixed, make little wet female powder;

2. get 25～70 order particles with sieving after the carrier drying;

3. the carrier that 2. female powder that 1. step is made and step make is put into to rotate in the dressing machine and is mixed, and adds auxiliary agents such as binding agent, stabilizing agent, synergist, colouring agent more respectively, and fully stirs, and makes female powder be coated on the carrier equably;

4. after the granule drying machine drying that will make, sieve and get the qualified products packing.

Good effect of the present invention is:

1. use chlopyrifos and phoxim binary built, contained two kinds of different insecticidal spectrums, thereby can play the effect that enlarges insecticidal spectrum, improves drug effect, reduces production costs.This complex preparation death by poisoning tick is strong to the insect toxic action, toxicity is medium, act on crop root and have certain conduction, when effectively killing soil insect, can take into account the control of insect on the ground in sugarcane seedling stage: phoxim has to insect that stronger speed is killed effect and toxicity is low toxicity in the preparation; Above-mentioned two kinds of insecticides are mixed by a certain percentage and can play obvious synergistic effect, show in Guangzhou Inst of Cane Sugar plant protection research promotion center " Toxicity Determination report "; Chlopyrifos and phoxim co-toxicity coefficient by 1: 2 and 2: 3 proportionings the time reaches 187.1 and 185.8, and synergistic effect is (co-toxicity coefficient CTC: less than 70, be antagonism very significantly; 70～150, be summation action; Greater than 150, be synergistic effect; Be extremely significantly synergistic effect greater than 200).Thereby determine insecticide of the present invention that the sugarcane soil insect is had the better prevention effect.

2. the present invention is granule on preparation, and adopts international advanced pesticide slow-release technology, and therefore can guarantee: this product lasting period is longer; Product is easy to transportation; Use safer, convenient; Because of its not with an organic solvent, so environmentally friendly.

3. product toxicity of the present invention is lower, and it is fast to degrade in soil and sugarcane, and persticide residue is low, to the person poultry safety.

Below in conjunction with embodiment the present invention is described in further detail.
